pthread_frame: make accesses to debug field be protected by owner lock.

The av_log() is done outside the lock, but this way the accesses to the
field (reads and writes) are always protected by a mutex. The av_log()
is not run inside the lock context because it may involve user callbacks
and doing that in performance-sensitive code is probably not a good idea.

This should fix occasional tsan warnings when running fate-h264, like:

- - It is recommended to build FFmpeg twice, first with minimal external dependencies so

-   can then be built. And last build FFmpeg with full dependancies (which may in turn depend on

-// 181230: comments on avs_load_library (helper for loading API entries dynamically into a struct using AVSC_NO_DECLSPEC define)
-// 181230: define alias AVS_FRAME_ALIGN as FRAME_ALIGN
-// 181230: remove unused form of avs_get_rowsize and avs_get_height (kept earlier for reference)
-// 190104: avs_load_library: smart fallback mechanism for Avisynth+ specific functions:
-//         if they are not loadable, they will work in a classic Avisynth compatible mode
-//         Example#1: e.g. avs_is_444 will call the existing avs_is_yv24 instead
-//         Example#2: avs_bits_per_component will return 8 for all colorspaces (Classic Avisynth supports only 8 bits/pixel)

-@item g keyint_min
-Set key frame placement.  The GOP size sets the maximum distance between
-key frames; if zero the output stream will be intra-only.  The minimum
-distance is ignored unless it is the same as the GOP size, in which case
-key frames will always appear at a fixed interval.  Not set by default,

-@section How do I run ffmpeg as a background task?
-
-ffmpeg normally checks the console input, for entries like "q" to stop
-and "?" to give help, while performing operations. ffmpeg does not have a way of
-detecting when it is running as a background task.
-When it checks the console input, that can cause the process running ffmpeg
-in the background to suspend.
-
-To prevent those input checks, allowing ffmpeg to run as a background task,
-use the @url{ffmpeg.html#stdin-option, @code{-nostdin} option}
-in the ffmpeg invocation. This is effective whether you run ffmpeg in a shell
-or invoke ffmpeg in its own process via an operating system API.
-
-As an alternative, when you are running ffmpeg in a shell, you can redirect
-standard input to @code{/dev/null} (on Linux and macOS)
-or @code{NUL} (on Windows). You can do this redirect either
-on the ffmpeg invocation, or from a shell script which calls ffmpeg.
-
-For example:
-
-@example
-ffmpeg -nostdin -i INPUT OUTPUT
-@end example
-
-or (on Linux, macOS, and other UNIX-like shells):
-
-@example
-ffmpeg -i INPUT OUTPUT </dev/null
-@end example
-
-or (on Windows):
-
-@example
-ffmpeg -i INPUT OUTPUT <NUL
-@end example
-
-@section How do I prevent ffmpeg from suspending with a message like @emph{suspended (tty output)}?
-
-If you run ffmpeg in the background, you may find that its process suspends.
-There may be a message like @emph{suspended (tty output)}. The question is how
-to prevent the process from being suspended.
-
-For example:
-
-@example
-% ffmpeg -i INPUT OUTPUT &> ~/tmp/log.txt &
-[1] 93352
-%
-[1]  + suspended (tty output)  ffmpeg -i INPUT OUTPUT &>
-@end example
-
-The message "tty output" notwithstanding, the problem here is that
-ffmpeg normally checks the console input when it runs. The operating system
-detects this, and suspends the process until you can bring it to the
-foreground and attend to it.
-
-The solution is to use the right techniques to tell ffmpeg not to consult
-console input. You can use the
-@url{ffmpeg.html#stdin-option, @code{-nostdin} option},
-or redirect standard input with @code{< /dev/null}.
-See FAQ
-@ref{background task, @emph{How do I run ffmpeg as a background task?}}

 @chapter Stream selection
 @c man begin STREAM SELECTION
 
-@command{ffmpeg} provides the @code{-map} option for manual control of stream selection in each
-output file. Users can skip @code{-map} and let ffmpeg perform automatic stream selection as
-described below. The @code{-vn / -an / -sn / -dn} options can be used to skip inclusion of
-video, audio, subtitle and data streams respectively, whether manually mapped or automatically
-selected, except for those streams which are outputs of complex filtergraphs.
+By default, @command{ffmpeg} includes only one stream of each type (video, audio, subtitle)
+present in the input files and adds them to each output file.  It picks the
+"best" of each based upon the following criteria: for video, it is the stream
+with the highest resolution, for audio, it is the stream with the most channels, for
+subtitles, it is the first subtitle stream. In the case where several streams of
+the same type rate equally, the stream with the lowest index is chosen.
 
-@section Description
-The sub-sections that follow describe the various rules that are involved in stream selection.
-The examples that follow next show how these rules are applied in practice.
-
-While every effort is made to accurately reflect the behavior of the program, FFmpeg is under
-continuous development and the code may have changed since the time of this writing.
-
-@subsection Automatic stream selection
-
-In the absence of any map options for a particular output file, ffmpeg inspects the output
-format to check which type of streams can be included in it, viz. video, audio and/or
-subtitles. For each acceptable stream type, ffmpeg will pick one stream, when available,
-from among all the inputs.
-
-It will select that stream based upon the following criteria:
-@itemize
-@item
-for video, it is the stream with the highest resolution,
-@item
-for audio, it is the stream with the most channels,
-@item
-for subtitles, it is the first subtitle stream found but there's a caveat.
-The output format's default subtitle encoder can be either text-based or image-based,
-and only a subtitle stream of the same type will be chosen.
-@end itemize
-
-In the case where several streams of the same type rate equally, the stream with the lowest
-index is chosen.
-
-Data or attachment streams are not automatically selected and can only be included
-using @code{-map}.
-@subsection Manual stream selection
-
-When @code{-map} is used, only user-mapped streams are included in that output file,
-with one possible exception for filtergraph outputs described below.
-
-@subsection Complex filtergraphs
-
-If there are any complex filtergraph output streams with unlabeled pads, they will be added
-to the first output file. This will lead to a fatal error if the stream type is not supported
-by the output format. In the absence of the map option, the inclusion of these streams leads
-to the automatic stream selection of their types being skipped. If map options are present,
-these filtergraph streams are included in addition to the mapped streams.
-
-Complex filtergraph output streams with labeled pads must be mapped once and exactly once.
-
-@subsection Stream handling
-
-Stream handling is independent of stream selection, with an exception for subtitles described
-below. Stream handling is set via the @code{-codec} option addressed to streams within a
-specific @emph{output} file. In particular, codec options are applied by ffmpeg after the
-stream selection process and thus do not influence the latter. If no @code{-codec} option is
-specified for a stream type, ffmpeg will select the default encoder registered by the output
-file muxer.
-
-An exception exists for subtitles. If a subtitle encoder is specified for an output file, the
-first subtitle stream found of any type, text or image, will be included. ffmpeg does not validate
-if the specified encoder can convert the selected stream or if the converted stream is acceptable
-within the output format. This applies generally as well: when the user sets an encoder manually,
-the stream selection process cannot check if the encoded stream can be muxed into the output file.
-If it cannot, ffmpeg will abort and @emph{all} output files will fail to be processed.
-
-@section Examples
-
-The following examples illustrate the behavior, quirks and limitations of ffmpeg's stream
-selection methods.
-
-They assume the following three input files.
-
-@verbatim
-
-input file 'A.avi'
-      stream 0: video 640x360
-      stream 1: audio 2 channels
-
-input file 'B.mp4'
-      stream 0: video 1920x1080
-      stream 1: audio 2 channels
-      stream 2: subtitles (text)
-      stream 3: audio 5.1 channels
-      stream 4: subtitles (text)
-
-input file 'C.mkv'
-      stream 0: video 1280x720
-      stream 1: audio 2 channels
-      stream 2: subtitles (image)
-@end verbatim
-
-@subsubheading Example: automatic stream selection
-@example
-ffmpeg -i A.avi -i B.mp4 out1.mkv out2.wav -map 1:a -c:a copy out3.mov
-@end example
-There are three output files specified, and for the first two, no @code{-map} options
-are set, so ffmpeg will select streams for these two files automatically.
-
-@file{out1.mkv} is a Matroska container file and accepts video, audio and subtitle streams,
-so ffmpeg will try to select one of each type.@*
-For video, it will select @code{stream 0} from @file{B.mp4}, which has the highest
-resolution among all the input video streams.@*
-For audio, it will select @code{stream 3} from @file{B.mp4}, since it has the greatest
-number of channels.@*
-For subtitles, it will select @code{stream 2} from @file{B.mp4}, which is the first subtitle
-stream from among @file{A.avi} and @file{B.mp4}.
-
-@file{out2.wav} accepts only audio streams, so only @code{stream 3} from @file{B.mp4} is
-selected.
-
-For @file{out3.mov}, since a @code{-map} option is set, no automatic stream selection will
-occur. The @code{-map 1:a} option will select all audio streams from the second input
-@file{B.mp4}. No other streams will be included in this output file.
-
-For the first two outputs, all included streams will be transcoded. The encoders chosen will
-be the default ones registered by each output format, which may not match the codec of the
-selected input streams.
-
-For the third output, codec option for audio streams has been set
-to @code{copy}, so no decoding-filtering-encoding operations will occur, or @emph{can} occur.
-Packets of selected streams shall be conveyed from the input file and muxed within the output
-file.
-
-@subsubheading Example: automatic subtitles selection
-@example
-ffmpeg -i C.mkv out1.mkv -c:s dvdsub -an out2.mkv
-@end example
-Although @file{out1.mkv} is a Matroska container file which accepts subtitle streams, only a
-video and audio stream shall be selected. The subtitle stream of @file{C.mkv} is image-based
-and the default subtitle encoder of the Matroska muxer is text-based, so a transcode operation
-for the subtitles is expected to fail and hence the stream isn't selected. However, in
-@file{out2.mkv}, a subtitle encoder is specified in the command and so, the subtitle stream is
-selected, in addition to the video stream. The presence of @code{-an} disables audio stream
-selection for @file{out2.mkv}.
-
-@subsubheading Example: unlabeled filtergraph outputs
-@example
-ffmpeg -i A.avi -i C.mkv -i B.mp4 -filter_complex "overlay" out1.mp4 out2.srt
-@end example
-A filtergraph is setup here using the @code{-filter_complex} option and consists of a single
-video filter. The @code{overlay} filter requires exactly two video inputs, but none are
-specified, so the first two available video streams are used, those of @file{A.avi} and
-@file{C.mkv}. The output pad of the filter has no label and so is sent to the first output file
-@file{out1.mp4}. Due to this, automatic selection of the video stream is skipped, which would
-have selected the stream in @file{B.mp4}. The audio stream with most channels viz. @code{stream 3}
-in @file{B.mp4}, is chosen automatically. No subtitle stream is chosen however, since the MP4
-format has no default subtitle encoder registered, and the user hasn't specified a subtitle encoder.
-
-The 2nd output file, @file{out2.srt}, only accepts text-based subtitle streams. So, even though
-the first subtitle stream available belongs to @file{C.mkv}, it is image-based and hence skipped.
-The selected stream, @code{stream 2} in @file{B.mp4}, is the first text-based subtitle stream.
-
-@subsubheading Example: labeled filtergraph outputs
-@example
-ffmpeg -i A.avi -i B.mp4 -i C.mkv -filter_complex "[1:v]hue=s=0[outv];overlay;aresample" \
-       -map '[outv]' -an        out1.mp4 \
-                                out2.mkv \
-       -map '[outv]' -map 1:a:0 out3.mkv
-@end example
-
-The above command will fail, as the output pad labelled @code{[outv]} has been mapped twice.
-None of the output files shall be processed.
-
-@example
-ffmpeg -i A.avi -i B.mp4 -i C.mkv -filter_complex "[1:v]hue=s=0[outv];overlay;aresample" \
-       -an        out1.mp4 \
-                  out2.mkv \
-       -map 1:a:0 out3.mkv
-@end example
-
-This command above will also fail as the hue filter output has a label, @code{[outv]},
-and hasn't been mapped anywhere.
-
-The command should be modified as follows,
-@example
-ffmpeg -i A.avi -i B.mp4 -i C.mkv -filter_complex "[1:v]hue=s=0,split=2[outv1][outv2];overlay;aresample" \
-        -map '[outv1]' -an        out1.mp4 \
-                                  out2.mkv \
-        -map '[outv2]' -map 1:a:0 out3.mkv
-@end example
-The video stream from @file{B.mp4} is sent to the hue filter, whose output is cloned once using
-the split filter, and both outputs labelled. Then a copy each is mapped to the first and third
-output files.
-
-The overlay filter, requiring two video inputs, uses the first two unused video streams. Those
-are the streams from @file{A.avi} and @file{C.mkv}. The overlay output isn't labelled, so it is
-sent to the first output file @file{out1.mp4}, regardless of the presence of the @code{-map} option.
-
-The aresample filter is sent the first unused audio stream, that of @file{A.avi}. Since this filter
-output is also unlabelled, it too is mapped to the first output file. The presence of @code{-an}
-only suppresses automatic or manual stream selection of audio streams, not outputs sent from
-filtergraphs. Both these mapped streams shall be ordered before the mapped stream in @file{out1.mp4}.
-
-The video, audio and subtitle streams mapped to @code{out2.mkv} are entirely determined by
-automatic stream selection.
-
-@file{out3.mkv} consists of the cloned video output from the hue filter and the first audio
-stream from @file{B.mp4}.

+ffserver [@var{options}]
+
+@chapter Description
+@c man begin DESCRIPTION
+
+@command{ffserver} is a streaming server for both audio and video.
+It supports several live feeds, streaming from files and time shifting
+on live feeds. You can seek to positions in the past on each live
+feed, provided you specify a big enough feed storage.
+
+@command{ffserver} is configured through a configuration file, which
+is read at startup. If not explicitly specified, it will read from
+@file{/etc/ffserver.conf}.
+
+@command{ffserver} receives prerecorded files or FFM streams from some
+@command{ffmpeg} instance as input, then streams them over
+RTP/RTSP/HTTP.
+
+An @command{ffserver} instance will listen on some port as specified
+in the configuration file. You can launch one or more instances of
+@command{ffmpeg} and send one or more FFM streams to the port where
+ffserver is expecting to receive them. Alternately, you can make
+@command{ffserver} launch such @command{ffmpeg} instances at startup.
+
+Input streams are called feeds, and each one is specified by a
+@code{<Feed>} section in the configuration file.
+
+For each feed you can have different output streams in various
+formats, each one specified by a @code{<Stream>} section in the
+configuration file.
+
+@chapter Detailed description
+
+@command{ffserver} works by forwarding streams encoded by
+@command{ffmpeg}, or pre-recorded streams which are read from disk.
+
+Precisely, @command{ffserver} acts as an HTTP server, accepting POST
+requests from @command{ffmpeg} to acquire the stream to publish, and
+serving RTSP clients or HTTP clients GET requests with the stream
+media content.
+
+A feed is an @ref{FFM} stream created by @command{ffmpeg}, and sent to
+a port where @command{ffserver} is listening.
+
+Each feed is identified by a unique name, corresponding to the name
+of the resource published on @command{ffserver}, and is configured by
+a dedicated @code{Feed} section in the configuration file.
+
+The feed publish URL is given by:
+@example
+http://@var{ffserver_ip_address}:@var{http_port}/@var{feed_name}
+@end example
+
+where @var{ffserver_ip_address} is the IP address of the machine where
+@command{ffserver} is installed, @var{http_port} is the port number of
+the HTTP server (configured through the @option{HTTPPort} option), and
+@var{feed_name} is the name of the corresponding feed defined in the
+configuration file.
+
+Each feed is associated to a file which is stored on disk. This stored
+file is used to send pre-recorded data to a player as fast as
+possible when new content is added in real-time to the stream.
+
+A "live-stream" or "stream" is a resource published by
+@command{ffserver}, and made accessible through the HTTP protocol to
+clients.
+
+A stream can be connected to a feed, or to a file. In the first case,
+the published stream is forwarded from the corresponding feed
+generated by a running instance of @command{ffmpeg}, in the second
+case the stream is read from a pre-recorded file.
+
+Each stream is identified by a unique name, corresponding to the name
+of the resource served by @command{ffserver}, and is configured by
+a dedicated @code{Stream} section in the configuration file.
+
+The stream access HTTP URL is given by:
+@example
+http://@var{ffserver_ip_address}:@var{http_port}/@var{stream_name}[@var{options}]
+@end example
+
+The stream access RTSP URL is given by:
+@example
+http://@var{ffserver_ip_address}:@var{rtsp_port}/@var{stream_name}[@var{options}]
+@end example
+
+@var{stream_name} is the name of the corresponding stream defined in
+the configuration file. @var{options} is a list of options specified
+after the URL which affects how the stream is served by
+@command{ffserver}. @var{http_port} and @var{rtsp_port} are the HTTP
+and RTSP ports configured with the options @var{HTTPPort} and
+@var{RTSPPort} respectively.
+
+In case the stream is associated to a feed, the encoding parameters
+must be configured in the stream configuration. They are sent to
+@command{ffmpeg} when setting up the encoding. This allows
+@command{ffserver} to define the encoding parameters used by
+the @command{ffmpeg} encoders.
+
+The @command{ffmpeg} @option{override_ffserver} commandline option
+allows one to override the encoding parameters set by the server.
+
+Multiple streams can be connected to the same feed.
+
+For example, you can have a situation described by the following
+graph:
+
+@verbatim
+               _________       __________
+              |         |     |          |

+@section FFM, FFM2 formats
+
+FFM and FFM2 are formats used by ffserver. They allow storing a wide variety of
+video and audio streams and encoding options, and can store a moving time segment
+of an infinite movie or a whole movie.
+
+FFM is version specific, and there is limited compatibility of FFM files
+generated by one version of ffmpeg/ffserver and another version of
+ffmpeg/ffserver. It may work but it is not guaranteed to work.
+
+FFM2 is extensible while maintaining compatibility and should work between
+differing versions of tools. FFM2 is the default.
+
+@section Status stream
+
+@command{ffserver} supports an HTTP interface which exposes the
+current status of the server.
+
+Simply point your browser to the address of the special status stream
+specified in the configuration file.
+
+For example if you have:
+@example
+<Stream status.html>
+Format status
+
+# Only allow local people to get the status
+ACL allow localhost
+ACL allow 192.168.0.0 192.168.255.255
+</Stream>
+@end example
+
+then the server will post a page with the status information when
+the special stream @file{status.html} is requested.
+
+@section How do I make it work?
+
+As a simple test, just run the following two command lines where INPUTFILE
+is some file which you can decode with ffmpeg:
+
+@example
+ffserver -f doc/ffserver.conf &
+ffmpeg -i INPUTFILE http://localhost:8090/feed1.ffm
+@end example
+
+At this point you should be able to go to your Windows machine and fire up
+Windows Media Player (WMP). Go to Open URL and enter
+
+@example
+    http://<linuxbox>:8090/test.asf
+@end example
+
+You should (after a short delay) see video and hear audio.
+
+WARNING: trying to stream test1.mpg doesn't work with WMP as it tries to
+transfer the entire file before starting to play.
+The same is true of AVI files.
+
+You should edit the @file{ffserver.conf} file to suit your needs (in
+terms of frame rates etc). Then install @command{ffserver} and
+@command{ffmpeg}, write a script to start them up, and off you go.
+
+@section What else can it do?
+
+You can replay video from .ffm files that was recorded earlier.
+However, there are a number of caveats, including the fact that the
+ffserver parameters must match the original parameters used to record the
+file. If they do not, then ffserver deletes the file before recording into it.
+(Now that I write this, it seems broken).
+
+You can fiddle with many of the codec choices and encoding parameters, and
+there are a bunch more parameters that you cannot control. Post a message
+to the mailing list if there are some 'must have' parameters. Look in
+ffserver.conf for a list of the currently available controls.
+
+It will automatically generate the ASX or RAM files that are often used
+in browsers. These files are actually redirections to the underlying ASF
+or RM file. The reason for this is that the browser often fetches the
+entire file before starting up the external viewer. The redirection files
+are very small and can be transferred quickly. [The stream itself is
+often 'infinite' and thus the browser tries to download it and never
+finishes.]
+
+@section Tips
+
+* When you connect to a live stream, most players (WMP, RA, etc) want to
+buffer a certain number of seconds of material so that they can display the
+signal continuously. However, ffserver (by default) starts sending data
+in realtime. This means that there is a pause of a few seconds while the
+buffering is being done by the player. The good news is that this can be
+cured by adding a '?buffer=5' to the end of the URL. This means that the
+stream should start 5 seconds in the past -- and so the first 5 seconds
+of the stream are sent as fast as the network will allow. It will then
+slow down to real time. This noticeably improves the startup experience.
+
+You can also add a 'Preroll 15' statement into the ffserver.conf that will
+add the 15 second prebuffering on all requests that do not otherwise
+specify a time. In addition, ffserver will skip frames until a key_frame
+is found. This further reduces the startup delay by not transferring data
+that will be discarded.
+
+@section Why does the ?buffer / Preroll stop working after a time?
+
+It turns out that (on my machine at least) the number of frames successfully
+grabbed is marginally less than the number that ought to be grabbed. This
+means that the timestamp in the encoded data stream gets behind realtime.
+This means that if you say 'Preroll 10', then when the stream gets 10
+or more seconds behind, there is no Preroll left.
+
+Fixing this requires a change in the internals of how timestamps are
+handled.
+
+@section Does the @code{?date=} stuff work.
+
+Yes (subject to the limitation outlined above). Also note that whenever you
+start ffserver, it deletes the ffm file (if any parameters have changed),
+thus wiping out what you had recorded before.
+
+The format of the @code{?date=xxxxxx} is fairly flexible. You should use one
+of the following formats (the 'T' is literal):
+
+@example
+* YYYY-MM-DDTHH:MM:SS     (localtime)
+* YYYY-MM-DDTHH:MM:SSZ    (UTC)
+@end example
+
+You can omit the YYYY-MM-DD, and then it refers to the current day. However
+note that @samp{?date=16:00:00} refers to 16:00 on the current day -- this
+may be in the future and so is unlikely to be useful.
+
+You use this by adding the ?date= to the end of the URL for the stream.
+For example:   @samp{http://localhost:8080/test.asf?date=2002-07-26T23:05:00}.

+@chapter Configuration file syntax
+
+@command{ffserver} reads a configuration file containing global
+options and settings for each stream and feed.
+
+The configuration file consists of global options and dedicated
+sections, which must be introduced by "<@var{SECTION_NAME}
+@var{ARGS}>" on a separate line and must be terminated by a line in
+the form "</@var{SECTION_NAME}>". @var{ARGS} is optional.
+
+Currently the following sections are recognized: @samp{Feed},
+@samp{Stream}, @samp{Redirect}.
+
+A line starting with @code{#} is ignored and treated as a comment.
+
+Name of options and sections are case-insensitive.

+@section ACL syntax
+An ACL (Access Control List) specifies the address which are allowed
+to access a given stream, or to write a given feed.
+
+It accepts the folling forms
+@itemize
+@item
+Allow/deny access to @var{address}.
+@example
+ACL ALLOW <address>
+ACL DENY <address>
+@end example
+
+@item
+Allow/deny access to ranges of addresses from @var{first_address} to
+@var{last_address}.
+@example
+ACL ALLOW <first_address> <last_address>
+ACL DENY <first_address> <last_address>
+@end example
+@end itemize
+
+You can repeat the ACL allow/deny as often as you like. It is on a per
+stream basis. The first match defines the action. If there are no matches,
+then the default is the inverse of the last ACL statement.
+
+Thus 'ACL allow localhost' only allows access from localhost.
+'ACL deny 1.0.0.0 1.255.255.255' would deny the whole of network 1 and
+allow everybody else.
+
+@section Global options
+@table @option
+@item HTTPPort @var{port_number}
+@item Port @var{port_number}
+@item RTSPPort @var{port_number}
+
+@var{HTTPPort} sets the HTTP server listening TCP port number,
+@var{RTSPPort} sets the RTSP server listening TCP port number.
+
+@var{Port} is the equivalent of @var{HTTPPort} and is deprecated.
+
+You must select a different port from your standard HTTP web server if
+it is running on the same computer.
+
+If not specified, no corresponding server will be created.
+
+@item HTTPBindAddress @var{ip_address}
+@item BindAddress @var{ip_address}
+@item RTSPBindAddress @var{ip_address}
+Set address on which the HTTP/RTSP server is bound. Only useful if you
+have several network interfaces.
+
+@var{BindAddress} is the equivalent of @var{HTTPBindAddress} and is
+deprecated.
+
+@item MaxHTTPConnections @var{n}
+Set number of simultaneous HTTP connections that can be handled. It
+has to be defined @emph{before} the @option{MaxClients} parameter,
+since it defines the @option{MaxClients} maximum limit.
+
+Default value is 2000.
+
+@item MaxClients @var{n}
+Set number of simultaneous requests that can be handled. Since
+@command{ffserver} is very fast, it is more likely that you will want
+to leave this high and use @option{MaxBandwidth}.
+
+Default value is 5.
+
+@item MaxBandwidth @var{kbps}
+Set the maximum amount of kbit/sec that you are prepared to consume
+when streaming to clients.
+
+Default value is 1000.
+
+@item CustomLog @var{filename}
+Set access log file (uses standard Apache log file format). '-' is the
+standard output.
+
+If not specified @command{ffserver} will produce no log.
+
+In case the commandline option @option{-d} is specified this option is
+ignored, and the log is written to standard output.
+
+@item NoDaemon
+Set no-daemon mode. This option is currently ignored since now
+@command{ffserver} will always work in no-daemon mode, and is
+deprecated.
+
+@item UseDefaults
+@item NoDefaults
+Control whether default codec options are used for the all streams or not.
+Each stream may overwrite this setting for its own. Default is @var{UseDefaults}.
+The lastest occurrence overrides previous if multiple definitions.
+@end table
+
+@section Feed section
+
+A Feed section defines a feed provided to @command{ffserver}.
+
+Each live feed contains one video and/or audio sequence coming from an
+@command{ffmpeg} encoder or another @command{ffserver}. This sequence
+may be encoded simultaneously with several codecs at several
+resolutions.
+
+A feed instance specification is introduced by a line in the form:
+@example
+<Feed FEED_FILENAME>
+@end example
+
+where @var{FEED_FILENAME} specifies the unique name of the FFM stream.
+
+The following options are recognized within a Feed section.
+
+@table @option
+@item File @var{filename}
+@item ReadOnlyFile @var{filename}
+Set the path where the feed file is stored on disk.
+
+If not specified, the @file{/tmp/FEED.ffm} is assumed, where
+@var{FEED} is the feed name.
+
+If @option{ReadOnlyFile} is used the file is marked as read-only and
+it will not be deleted or updated.
+
+@item Truncate
+Truncate the feed file, rather than appending to it. By default
+@command{ffserver} will append data to the file, until the maximum
+file size value is reached (see @option{FileMaxSize} option).
+
+@item FileMaxSize @var{size}
+Set maximum size of the feed file in bytes. 0 means unlimited. The
+postfixes @code{K} (2^10), @code{M} (2^20), and @code{G} (2^30) are
+recognized.
+
+Default value is 5M.
+
+@item Launch @var{args}
+Launch an @command{ffmpeg} command when creating @command{ffserver}.
+
+@var{args} must be a sequence of arguments to be provided to an
+@command{ffmpeg} instance. The first provided argument is ignored, and
+it is replaced by a path with the same dirname of the @command{ffserver}
+instance, followed by the remaining argument and terminated with a
+path corresponding to the feed.
+
+When the launched process exits, @command{ffserver} will launch
+another program instance.
+
+In case you need a more complex @command{ffmpeg} configuration,
+e.g. if you need to generate multiple FFM feeds with a single
+@command{ffmpeg} instance, you should launch @command{ffmpeg} by hand.
+
+This option is ignored in case the commandline option @option{-n} is
+specified.
+
+@item ACL @var{spec}
+Specify the list of IP address which are allowed or denied to write
+the feed. Multiple ACL options can be specified.
+@end table
+
+@section Stream section
+
+A Stream section defines a stream provided by @command{ffserver}, and
+identified by a single name.
+
+The stream is sent when answering a request containing the stream
+name.
+
+A stream section must be introduced by the line:
+@example
+<Stream STREAM_NAME>
+@end example
+
+where @var{STREAM_NAME} specifies the unique name of the stream.
+
+The following options are recognized within a Stream section.
+
+Encoding options are marked with the @emph{encoding} tag, and they are
+used to set the encoding parameters, and are mapped to libavcodec
+encoding options. Not all encoding options are supported, in
+particular it is not possible to set encoder private options. In order
+to override the encoding options specified by @command{ffserver}, you
+can use the @command{ffmpeg} @option{override_ffserver} commandline
+option.
+
+Only one of the @option{Feed} and @option{File} options should be set.
+
+@table @option
+@item Feed @var{feed_name}
+Set the input feed. @var{feed_name} must correspond to an existing
+feed defined in a @code{Feed} section.
+
+When this option is set, encoding options are used to setup the
+encoding operated by the remote @command{ffmpeg} process.
+
+@item File @var{filename}
+Set the filename of the pre-recorded input file to stream.
+
+When this option is set, encoding options are ignored and the input
+file content is re-streamed as is.
+
+@item Format @var{format_name}
+Set the format of the output stream.
+
+Must be the name of a format recognized by FFmpeg. If set to
+@samp{status}, it is treated as a status stream.
+
+@item InputFormat @var{format_name}
+Set input format. If not specified, it is automatically guessed.
+
+@item Preroll @var{n}
+Set this to the number of seconds backwards in time to start. Note that
+most players will buffer 5-10 seconds of video, and also you need to allow
+for a keyframe to appear in the data stream.
+
+Default value is 0.
+
+@item StartSendOnKey
+Do not send stream until it gets the first key frame. By default
+@command{ffserver} will send data immediately.
+
+@item MaxTime @var{n}
+Set the number of seconds to run. This value set the maximum duration
+of the stream a client will be able to receive.
+
+A value of 0 means that no limit is set on the stream duration.
+
+@item ACL @var{spec}
+Set ACL for the stream.
+
+@item DynamicACL @var{spec}
+
+@item RTSPOption @var{option}
+
+@item MulticastAddress @var{address}
+

+Set favicon (favourite icon) for the server status page. It is ignored
+for regular streams.
+
+@item Author @var{value}
+@item Comment @var{value}
+@item Copyright @var{value}
+@item Title @var{value}
+Set metadata corresponding to the option. All these options are
+deprecated in favor of @option{Metadata}.
+
+@item Metadata @var{key} @var{value}
+Set metadata value on the output stream.
+
+@item UseDefaults

     The characteristics of the data (resolution, sample rate, etc.) are

     show different characteristics. In particular, a video reference can
     point to only a part of a video buffer.

+    The AVFilterBufferRef structure has a perms field that describes what

+    parts of the buffer that have already been covered by the draw_slice
+    method.
 
-    A filter can ensure that a frame is writable at some point of the code
-    by using the ff_inlink_make_frame_writable() function. It will duplicate
-    the frame if needed.
+    The value is a binary OR of the following constants:
 
-    A filter can ensure that the frame passed to the filter_frame() callback
-    is writable by setting the needs_writable flag on the corresponding

+      always true and is there for self-documentation.
+
+    * AV_PERM_WRITE: the owner can modify the buffer data.
+
+    * AV_PERM_PRESERVE: the owner can rely on the fact that the buffer data
+      will not be modified by previous filters.
+
+    * AV_PERM_REUSE: the owner can output the buffer several times, without
+      modifying the data in between.
+
+    * AV_PERM_REUSE2: the owner can output the buffer several times and
+      modify the data in between (useless without the WRITE permissions).
+
+    * AV_PERM_ALIGN: the owner can access the data using fast operations
+      that require data alignment.
+
+    The READ, WRITE and PRESERVE permissions are about sharing the same
+    buffer between several filters to avoid expensive copies without them
+    doing conflicting changes on the data.
+
+    The REUSE and REUSE2 permissions are about special memory for direct
+    rendering. For example a buffer directly allocated in video memory must
+    not modified once it is displayed on screen, or it will cause tearing;
+    it will therefore not have the REUSE2 permission.
+
+    The ALIGN permission is about extracting part of the buffer, for
+    copy-less padding or cropping for example.
+
+
+    References received on input pads are guaranteed to have all the
+    permissions stated in the min_perms field and none of the permissions
+    stated in the rej_perms.
+
+    References obtained by ff_get_video_buffer and ff_get_audio_buffer are
+    guaranteed to have at least all the permissions requested as argument.
+
+    References created by avfilter_ref_buffer have the same permissions as
+    the original reference minus the ones explicitly masked; the mask is
+    usually ~0 to keep the same permissions.
+
+    Filters should remove permissions on reference they give to output
+    whenever necessary. It can be automatically done by setting the
+    rej_perms field on the output pad.
+
+    Here are a few guidelines corresponding to common situations:
+
+    * Filters that modify and forward their frame (like drawtext) need the
+      WRITE permission.
+
+    * Filters that read their input to produce a new frame on output (like
+      scale) need the READ permission on input and must request a buffer
+      with the WRITE permission.
+
+    * Filters that intend to keep a reference after the filtering process
+      is finished (after filter_frame returns) must have the PRESERVE
+      permission on it and remove the WRITE permission if they create a new
+      reference to give it away.
+
+    * Filters that intend to modify a reference they have kept after the end
+      of the filtering process need the REUSE2 permission and must remove
+      the PRESERVE permission if they create a new reference to give it
+      away.
 
 
 Frame scheduling
@@ -127,100 +189,11 @@ Frame scheduling
   Simple filters that output one frame for each input frame should not have
   to worry about it.
 
-  There are two design for filters: one using the filter_frame() and
-  request_frame() callbacks and the other using the activate() callback.
-
-  The design using filter_frame() and request_frame() is legacy, but it is
-  suitable for filters that have a single input and process one frame at a
-  time. New filters with several inputs, that treat several frames at a time
-  or that require a special treatment at EOF should probably use the design
-  using activate().
-
-  activate
-  --------
-
-    This method is called when something must be done in a filter; the
-    definition of that "something" depends on the semantic of the filter.
-
-    The callback must examine the status of the filter's links and proceed
-    accordingly.
-
-    The status of output links is stored in the frame_wanted_out, status_in
-    and status_out fields and tested by the ff_outlink_frame_wanted()
-    function. If this function returns true, then the processing requires a
-    frame on this link and the filter is expected to make efforts in that
-    direction.
-
-    The status of input links is stored by the status_in, fifo and
-    status_out fields; they must not be accessed directly. The fifo field
-    contains the frames that are queued in the input for processing by the
-    filter. The status_in and status_out fields contains the queued status
-    (EOF or error) of the link; status_in is a status change that must be
-    taken into account after all frames in fifo have been processed;
-    status_out is the status that have been taken into account, it is final
-    when it is not 0.
-
-    The typical task of an activate callback is to first check the backward
-    status of output links, and if relevant forward it to the corresponding
-    input. Then, if relevant, for each input link: test the availability of
-    frames in fifo and process them;  if no frame is available, test and
-    acknowledge a change of status using ff_inlink_acknowledge_status(); and
-    forward the result (frame or status change) to the corresponding input.
-    If nothing is possible, test the status of outputs and forward it to the
-    corresponding input(s). If still not possible, return FFERROR_NOT_READY.
-
-    If the filters stores internally one or a few frame for some input, it
-    can consider them to be part of the FIFO and delay acknowledging a
-    status change accordingly.
-
-    Example code:
-
-    ret = ff_outlink_get_status(outlink);
-    if (ret) {
-        ff_inlink_set_status(inlink, ret);
-        return 0;
-    }
-    if (priv->next_frame) {
-        /* use it */
-        return 0;
-    }
-    ret = ff_inlink_consume_frame(inlink, &frame);
-    if (ret < 0)
-        return ret;
-    if (ret) {
-        /* use it */
-        return 0;
-    }
-    ret = ff_inlink_acknowledge_status(inlink, &status, &pts);
-    if (ret) {
-        /* flush */
-        ff_outlink_set_status(outlink, status, pts);
-        return 0;
-    }
-    if (ff_outlink_frame_wanted(outlink)) {
-        ff_inlink_request_frame(inlink);
-        return 0;
-    }
-    return FFERROR_NOT_READY;
-
-    The exact code depends on how similar the /* use it */ blocks are and
-    how related they are to the /* flush */ block, and needs to apply these
-    operations to the correct inlink or outlink if there are several.
-
-    Macros are available to factor that when no extra processing is needed:
-
-    FF_FILTER_FORWARD_STATUS_BACK(outlink, inlink);
-    FF_FILTER_FORWARD_STATUS_ALL(outlink, filter);
-    FF_FILTER_FORWARD_STATUS(inlink, outlink);
-    FF_FILTER_FORWARD_STATUS_ALL(inlink, filter);
-    FF_FILTER_FORWARD_WANTED(outlink, inlink);
-
