0887f1835d libopenjpegenc: fix out-of-bounds reads when filling the edges
The calculation of width/height should round up, not round down to
prevent setting width or height to 0.

Also image->comps[compno].w is unsigned (at least in openjpeg2), so the
calculation could silently wrap around without the explicit cast to int.

ada229e66f configure: fix detection of libopenjpeg
Use check_lib2 to test the header together with the function. This is
necessary, because '-DOPJ_STATIC' changes what the included header does.

Also add '-DOPJ_STATIC' to CPPFLAGS, so that it isn't necessary to
hardcode this in libavcodec/libopenjpeg{dec,enc}.c.

Finally, check for non-static openjpeg 2.1, too.

f3c1a76ffd avformat/allformats: Making av_register_all() thread-safe.
When multiple threads tries to call av_register_all(), the first thread sets
initialized to 1 and do the register process. At the same time, other thread might
also call av_register_all(), which returns immediately because initialized is set to 1
(even when it has not completed registering codecs). We can avoid this problem
if we set initialised to 1 while exiting from function.

This reverts commit cb8646af24.

This change has brough more issues than benefits, between compilation
time failures depending on flags used and code miscompilation causing
runtime crashes.

See the "[PATCH 2/2] configure: Enable GCC vectorization on ≥4.9"
thread in the ffmpeg-devel mailing list for the relevant discussion.

069eea16d9 libavformat/oggdec: Free stream private when header parsing fails.
Leaking this private structure opens up the possibility that it may
be re-used when parsing later packets in the stream. This is
problematic if the later packets are not the same codec type (e.g.
private allocated during Vorbis parsing, but later packets are Opus
and the private is assumed to be the oggopus_private type in
opus_header()).

to be able to build it, and for that we need to make sure we don't use
incompatible assembler code which makes the build fail. Ifdefing the
offending code is sufficient to fix the problem.

666754c665 pgssubdec: fix subpicture output colorspace and range
Functionality used before didn't widen the values from limited to
full range. Additionally, now the decoder uses BT.709 where it
should be used according to the video resolution.

Default for not yet set colorimetry is BT.709 due to most observed
HDMV content being HD.

BT.709 coefficients were gathered from the first two parts of BT.709
to BT.2020 conversion guide in ARIB STD-B62 (Pt. 1, Chapter 6.2.2).
They were additionally confirmed by manually calculating values.

Fixes #4637

76573c5239 avcodec/h264: Fix for H.264 configuration parsing
Sometimes video fails to decode if H.264 configuration changes mid stream.
The reason is that configuration parser assumes that nal_ref_idc is equal to 11b
while actually some codecs but 01b there. The H.264 spec is somewhat
vague about this but it looks like it allows any non-zero nal_ref_idc for sps/pps.

47f0d80ee0 avfilter/src_movie: fix how we check for overflows with seek_point
Currently, if the movie source filter is used and a seek_point is
specified on a file that has a negative start time, ffmpeg will fail.

An easy way to reproduce this is as follows:
$ ffmpeg -vsync passthrough -filter_complex 'color=d=10,setpts=PTS-1/TB' test.mp4
$ ffmpeg -filter_complex 'movie=filename=test.mp4:seek_point=2' -f null -

The problem is caused by checking for int64_t overflow the wrong way.
In general, to check whether a + b overflows, it is not enough to do:
    a > INT64_MAX - b
because b might be negative; the correct way is:
    b > 0 && > a > INT64_MAX - b

f281cb4ea9 lavc/aacenc_utils: replace powf(x,y) by expf(logf(x), y)
This is ~2x faster for y not an integer on Haswell+GCC, and should
generally be faster due to the fact that anyway powf essentially does
this under the hood. Made an inline function in lavu/internal.h for this
purpose.

Note that there are some accuracy differences, that should generally be
negligible. In particular, FATE still passes on this platform.

Results in ~ 7% speedup in aac encoding with -march=native, Haswell+GCC.
before:
ffmpeg -i sin.flac -acodec aac -y sin_new.aac  6.05s user 0.06s system 104% cpu 5.821 total

after:
ffmpeg -i sin.flac -acodec aac -y sin_new.aac  5.67s user 0.03s system 105% cpu 5.416 total

This is also faster than an alternative approach that pulls in powf, gets rid of
the crufty NaN checks and other special cases, exploits knowledge about the intervals, etc.
This of course does not exclude smarter approaches; just suggests that
there would need to be significant work on this front of lower utility than
searches for hotspots elsewhere.

and more importantly a non-negligible speedup (~ 8%) to overall AAC encoding:

new:

This also improves accuracy of the expression by ~ 2 ulp in some cases.

daa6dc0a3b avformat/rtpdec_jpeg: fix low contrast image on low quality setting
Original mail and my own followup on ffmpeg-user earlier today:

I have a device sending out a MJPEG/RTP stream on a low quality setting.
Decoding and displaying the video with libavformat results in a washed
out, low contrast, greyish image. Playing the same stream with VLC results
in proper color representation.

Screenshots for comparison:

  http://zevv.nl/div/libav/shot-ffplay.jpg
  http://zevv.nl/div/libav/shot-vlc.jpg

A pcap capture of a few seconds of video and SDP file for playing the
stream are available at

  http://zevv.nl/div/libav/mjpeg.pcap
  http://zevv.nl/div/libav/mjpeg.sdp

I believe the problem might be in the calculation of the quantization
tables in the function create_default_qtables(), the attached patch
solves the issue for me.

The problem is that the argument 'q' is of the type uint8_t. According to the
JPEG standard, if 1 <= q <= 50, the scale factor 'S' should be 5000 / Q.
Because the create_default_qtables() reuses the variable 'q' to store the
result of this calculation, for small values of q < 19, q wil subsequently
overflow and give wrong results in the calculated quantization tables. The
patch below uses a new variable 'S' (same name as in RFC2435) with the proper
range to store the result of the division.

56c4dca5ae avformat/rtpenc: Fix integer overflow in NTP_TO_RTP_FORMAT
RTCP synchronization packet was broken since commit in ffmpeg version > 2.8.3
(commit: e04b039b15) Since this commit (2e814d0329)
"rtpenc: Simplify code by introducing a macro for rescaling NTP timestamps", NTP_TO_RTP_FORMAT
uses av_rescale_rnd() function to add the data to the packet.

This causes an overflow in the av_rescale_rnd() function and it will return INT64_MIN.
Causing the NTP stamp in the RTCP packet to have an invalid value.

Github: Closes #182

Reverting commit '2e814d0329aded98c811d0502839618f08642685' solves the problem.

b80083a5c1 ffserver&ffm: Fixed issues preventing ffserver write_index and files_size from being set correctly which was breaking ffserver streaming.
I discovered that ffserver streaming was broken (it seems like it has been since 20th November) and I opened a ticket for this (https://trac.ffmpeg.org/ticket/5250 <https://trac.ffmpeg.org/ticket/5250>).

I spent yesterday learning git bisect (with the kind help of cehoyos) to painstakingly track down the cause. This was made more difficult due to the presence of a segfault in ffserver during the period where the bug was introduced so I first had to identify when and how that was fixed and then retrospectively apply that fix again for each step of the second git bisect to find the actual bug.

Anyway, the fruits of my labour are the innocent looking patch below to correct a couple of typos and define a valid range for two variables.

### Incompatible libraries
incompatible libraries
----------------------
There are certain libraries you can combine with FFmpeg whose licenses are not
compatible with the GPL and/or the LGPL. If you wish to enable these
libraries, even in circumstances that their license may be incompatible, pass
`--enable-nonfree` to configure. But note that if you enable any of these
libraries the resulting binary will be under a complex license mix that is
more restrictive than the LGPL and that may result in additional obligations.
It is possible that these restrictions cause the resulting binary to be
unredistributable.
The Fraunhofer FDK AAC and OpenSSL libraries are under licenses which are
incompatible with the GPLv2 and v3. To the best of our knowledge, they are
compatible with the LGPL.
The NVENC library, while its header file is licensed under the compatible MIT
license, requires a proprietary binary blob at run time, and is deemed to be
incompatible with the GPL. We are not certain if it is compatible with the
LGPL, but we require `--enable-nonfree` even with LGPL configurations in case
it is not.
The Fraunhofer AAC library and FAAC are under licenses which
are incompatible with the GPLv2 and v3. We do not know for certain if their

API changes, most recent first:
2017-03-31 - 9033e8723c - lavu 55.57.100 - spherical.h
Add av_spherical_projection_name().
Add av_spherical_from_name().
2017-03-30 - 4cda23f1f1 - lavu 55.53.100 / 55.27.0 - hwcontext.h
Add av_hwframe_map() and associated AV_HWFRAME_MAP_* flags.
Add av_hwframe_ctx_create_derived().
2017-03-29 - bfdcdd6d82 - lavu 55.52.100 - avutil.h
add av_fourcc_make_string() function and av_fourcc2str() macro to replace
av_get_codec_tag_string() from lavc.
2017-03-27 - ddef3d902f - lavf 57.68.100 - avformat.h
Deprecate that demuxers export the stream rotation angle in AVStream.metadata
(via an entry named "rotate"). Use av_stream_get_side_data() with
AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
av_display_rotation_get(). The same is done for muxing. Instead of adding a
"rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
to be added to the AVStream.
2017-03-23 - 7e4ba776a2 - lavc 57.85.101 - avcodec.h
vdpau hardware accelerated decoding now supports the new hwaccel API, which
can create the decoder context and allocate hardware frame automatically.
See AVCodecContext.hw_device_ctx and AVCodecContext.hw_frames_ctx.
2017-03-23 - 156bd8278f - lavc 57.85.100 - avcodec.h
Add AVCodecContext.hwaccel_flags field. This will control some hwaccels at
a later point.

Add AVIO_SEEKABLE_TIME flag.
2017-03-21 - d682ae70b4 - lavf 57.66.105, lavc 57.83.101 - avformat.h, avcodec.h
Deprecate AVFMT_FLAG_KEEP_SIDE_DATA. It will be ignored after the next major
bump, and libavformat will behave as if it were always set.
Deprecate av_packet_merge_side_data() and av_packet_split_side_data().
2016-03-20 - 8200b16a9c - lavu 55.50.100 / 55.21.0 - imgutils.h
Add av_image_copy_uc_from(), a version of av_image_copy() for copying

Add AV_PIX_FMT_FLAG_BAYER pixel format flag.
2017-03-18 - 3796fb2692 - lavfi 6.77.100 - avfilter.h
Deprecate AVFilterGraph.resample_lavr_opts
It's never been used by avfilter nor passed to anything.
2017-02-10 - 1b7ffddb3a - lavu 55.48.100 / 55.33.0 - spherical.h
Add AV_SPHERICAL_EQUIRECTANGULAR_TILE, av_spherical_tile_bounds(),
and projection-specific properties (bound_left, bound_top, bound_right,
bound_bottom, padding) to AVSphericalMapping.
2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
native decoder format. (The default value is not changed.)
2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
Remove requirement to use AVOption or accessors to access certain fields
in AVFrame, AVCodecContext, and AVFormatContext that were previously
documented as "no direct access" allowed.
2017-02-13 - c1a5fca06f - lavc 57.80.100 - avcodec.h
Add AVCodecContext.hw_device_ctx.
2017-02-11 - e3af49b14b - lavu 55.47.100 - frame.h

Deprecate struct vaapi_context and the vaapi.h installed header.
Callers should set AVCodecContext.hw_frames_ctx instead.
2017-01-12 - dbe9dbed31 - lavfi 6.69.100 - buffersink.h
Add av_buffersink_get_*() functions.
2017-01-06 - 9488032e10 - lavf 57.62.100 - avio.h

2016-10-07 - 3f9137c / 32c8359 - lavc 57.61.100 / 57.24.0 - avcodec.h
Decoders now export the frame timestamp as AVFrame.pts. It was
previously exported as AVFrame.pkt_pts, which is now deprecated.
Note: When decoding, AVFrame.pts uses the stream/packet timebase,
and not the codec timebase.
2016-09-28 - eba0414 - lavu 55.32.100 / 55.16.0 - hwcontext.h hwcontext_qsv.h
Add AV_HWDEVICE_TYPE_QSV and a new installed header with QSV-specific

Add AV_CODEC_CAP_AVOID_PROBING codec capability flag.
2016-09-14 - ae1dd0c - lavf 57.49.100 - avformat.h
Add avformat_transfer_internal_stream_timing_info helper to help with stream
copy.
2016-08-29 - 4493390 - lavfi 6.58.100 - avfilter.h
Add AVFilterContext.nb_threads.
2016-08-15 - c3c4c72 - lavc 57.53.100 - avcodec.h

field in AVCodecParameters.
2016-08-15 - b746ed7 - lavc 57.52.100 - avcodec.h
Add a new API for chained BSF filters and passthrough (null) BSF --
av_bsf_list_alloc(), av_bsf_list_free(), av_bsf_list_append(),
av_bsf_list_append2(), av_bsf_list_finalize(), av_bsf_list_parse_str()
and av_bsf_get_null_filter().
2016-08-04 - 82a33c8 - lavf 57.46.100 - avformat.h
Add av_get_frame_filename2()
2016-07-09 - 775389f / 90f469a - lavc 57.50.100 / 57.20.0 - avcodec.h
Add FF_PROFILE_H264_MULTIVIEW_HIGH and FF_PROFILE_H264_STEREO_HIGH.
2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
Moved codecpar field from AVStream to the end of the struct, so that
the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h
Moved hw_frames_ctx field from AVFrame to the end of the struct, so that
the following private fields are in the same location as in FFmpeg 3.0 (lavu 55.17.103).
2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
Fix accidental ABI breakage in AVFilterContext.
ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
compatible with lavfi>=6.47.100. Potentially also affects other users of
libavfilter if they are using one of the affected fields.

"flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
the reset of the ASS ReadOrder field on flush. This affects the content of
AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
previous entry).
2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
Add a "sub_text_format" subtitles decoding option allowing the values "ass"
(recommended) and "ass_with_timings" (not recommended, deprecated, default).
The default value for this option will change to "ass" at the next major
libavcodec version bump.
The current default is "ass_with_timings" for compatibility. This means that
all subtitles text decoders currently still output ASS with timings printed
as strings in the AVSubtitles.rects[N]->ass fields.
Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
timing is limited to a 1/100 time base, so this is relevant for any subtitles
format needing a bigger one), ease timing adjustments, and prevents the need
of removing the timing from the decoded string yourself. This form is also
known as "the Matroska form". The timing information (start time, duration)
can be found in the AVSubtitles fields.

Opus encoder.
libfaac AAC (Advanced Audio Coding) encoder wrapper.
This is a native FFmpeg encoder for the Opus format. Currently its in development and
only implements the CELT part of the codec. Its quality is usually worse and at best
is equal to the libopus encoder.
This encoder is of much lower quality and is more unstable than any other AAC
encoders, so it's highly recommended to instead use other encoders, like
@ref{aacenc,,the native FFmpeg AAC encoder}.
This encoder also requires the presence of the libfaac headers and library
during configuration. You need to explicitly configure the build with
@code{--enable-libfaac --enable-nonfree}.
@subsection Options
@table @option
@item b
Set bit rate in bits/s. If unspecified it uses the number of channels and the layout
to make a good guess.
The following shared FFmpeg codec options are recognized.
@item opus_delay
Sets the maximum delay in milliseconds. Lower delays than 20ms will very quickly
decrease quality.
The following options are supported by the libfaac wrapper. The
@command{faac}-equivalent of the options are listed in parentheses.
@table @option
@item b (@emph{-b})
Set bit rate in bits/s for ABR (Average Bit Rate) mode. If the bit rate
is not explicitly specified, it is automatically set to a suitable
value depending on the selected profile. @command{faac} bitrate is
expressed in kilobits/s.
Note that libfaac does not support CBR (Constant Bit Rate) but only
ABR (Average Bit Rate).
If VBR mode is enabled this option is ignored.
@item ar (@emph{-R})
Set audio sampling rate (in Hz).
@item ac (@emph{-c})
Set the number of audio channels.
@item cutoff (@emph{-C})
Set cutoff frequency. If not specified (or explicitly set to 0) it
will use a value automatically computed by the library. Default value
is 0.
@item profile
Set audio profile.

@item global_quality
Set quality in VBR mode as an integer number of lambda units.
Only relevant when VBR mode is enabled with @code{flags +qscale}. The
value is converted to QP units by dividing it by @code{FF_QP2LAMBDA},
and used to set the quality value used by libfaac. A reasonable range
for the option value in QP units is [10-500], the higher the value the
higher the quality.
@item q (@emph{-q})
Enable VBR mode when set to a non-negative value, and set constant
quality value as a double floating point value in QP units.
The value sets the quality value used by libfaac. A reasonable range
for the option value is [10-500], the higher the value the higher the
quality.
This option is valid only using the @command{ffmpeg} command-line
tool. For library interface users, use @option{global_quality}.

CONTEXT
=======
The FFmpeg project merges all the changes from the Libav project
(https://libav.org) since the origin of the fork (around 2011).
With the exceptions of some commits due to technical/political disagreements or
issues, the changes are merged on a more or less regular schedule (daily for
years thanks to Michael, but more sparse nowadays).
WHY
===
The majority of the active developers believe the project needs to keep this
policy for various reasons.
The most important one is that we don't want our users to have to choose
between two distributors of libraries of the exact same name in order to have a
different set of features and bugfixes. By taking the responsibility of
unifying the two codebases, we allow users to benefit from the changes from the
two teams.
Today, FFmpeg has a much larger user database (we are distributed by every
major distribution), so we consider this mission a priority.
A different approach to the merge could have been to pick the changes we are
interested in and drop most of the cosmetics and other less important changes.
Unfortunately, this makes the following picks much harder, especially since the
Libav project is involved in various deep API changes. As a result, we decide
to virtually take everything done there.
Any Libav developer is of course welcome anytime to contribute directly to the
FFmpeg tree. Of course, we fully understand and are forced to accept that very
few Libav developers are interested in doing so, but we still want to recognize
their work. This leads us to create merge commits for every single one from
Libav. The original commit appears totally unchanged with full authorship in
our history (and the conflict are solved in the merge one). That way, not a
single thing from Libav will be lost in the future in case some reunification
happens, or that project disappears one way or another.
DOWNSIDES
=========
Of course, there are many downsides to this approach.
- It causes a non negligible merge commits pollution. We make sure there are
not several level of merges entangled (we do a 1:1 merge/commit), but it's
still a non-linear history.
- Many duplicated work. For instance, we added libavresample in our tree to
keep compatibility with Libav when our libswresample was already covering the
exact same purpose. The same thing happened for various elements such as the
ProRes support (but differences in features, bugs, licenses, ...). There are
many work to do to unify them, and any help is very much welcome.
- So much manpower from both FFmpeg and Libav is lost because of this mess. We
know it, and we don't know how to fix it. It takes incredible time to do
these merges, so we have even less time to work on things we personally care
about. The bad vibes also do not help with keeping our developers motivated.
- There is a growing technical risk factor with the merges due to the codebase
differing more and more.
MERGE GUIDELINES
================
The following gives developer guidelines on how to proceed when merging Libav commits.
Before starting, you can reduce the risk of errors on merge conflicts by using
a different merge conflict style:
$ git config --global merge.conflictstyle diff3
tools/libav-merge-next-commit is a script to help merging the next commit in
the queue. It assumes a remote named libav. It has two modes: merge, and noop.
The noop mode creates a merge with no change to the HEAD. You can pass a hash
as extra argument to reference a justification (it is common that we already
have the change done in FFmpeg).
Also see tools/murge, you can copy and paste a 3 way conflict into its stdin
and it will display colored diffs. Any arguments to murge (like ones to suppress
whitespace differences) are passed into colordiff.
TODO/FIXME/UNMERGED
===================
Stuff that didn't reach the codebase:
-------------------------------------
- HEVC DSP and x86 MC SIMD improvements from Libav (see https://ffmpeg.org/pipermail/ffmpeg-devel/2015-December/184777.html)
- 1f821750f hevcdsp: split the qpel functions by width instead of by the subpixel fraction
- 818bfe7f0 hevcdsp: split the epel functions by width
- 688417399 hevcdsp: split the pred functions by width
- a853388d2 hevc: change the stride of the MC buffer to be in bytes instead of elements
- 0cef06df0 checkasm: add HEVC MC tests
- e7078e842 hevcdsp: add x86 SIMD for MC
- VAAPI VP8 decode hwaccel (currently under review: http://ffmpeg.org/pipermail/ffmpeg-devel/2017-February/thread.html#207348)
- Removal of the custom atomic API (5cc0057f49, see http://ffmpeg.org/pipermail/ffmpeg-devel/2017-March/209003.html)
- Use the new bitstream filter for extracting extradata (8e2ea69135 and 096a8effa3, see https://ffmpeg.org/pipermail/ffmpeg-devel/2017-March/209068.html)
- Read aac_adtstoasc extradata updates from packet side data on Matroska once mov and the bsf in question are fixed (See 13a211e632 and 5ef1959080)
Collateral damage that needs work locally:
------------------------------------------
- Merge proresdec2.c and proresdec_lgpl.c
- Merge proresenc_anatoliy.c and proresenc_kostya.c
- Remove ADVANCED_PARSER in libavcodec/hevc_parser.c
- Fix MIPS AC3 downmix
- hlsenc encryption support may need some adjustment (see edc43c571d)
Extra changes needed to be aligned with Libav:
----------------------------------------------
- Switching our examples to the new encode/decode API (see 67d28f4a0f)
- HEVC IDCT bit depth 12-bit support (Libav added 8 and 10 but doesn't have 12)

Reserve the specified amount of bytes for the OpenDML master index of each
stream within the file header. By default additional master indexes are
embedded within the data packets if there is no space left in the first master
index and are linked together as a chain of indexes. This index structure can
cause problems for some use cases, e.g. third-party software strictly relying
on the OpenDML index specification or when file seeking is slow. Reserving
enough index space in the file header avoids these problems.
The required index space depends on the output file size and should be about 16
bytes per gigabyte. When this option is omitted or set to zero the necessary
index space is guessed.

@section fifo
The fifo pseudo-muxer allows the separation of encoding and muxing by using
first-in-first-out queue and running the actual muxer in a separate thread. This
is especially useful in combination with the @ref{tee} muxer and can be used to
send data to several destinations with different reliability/writing speed/latency.
API users should be aware that callback functions (interrupt_callback,
io_open and io_close) used within its AVFormatContext must be thread-safe.

as a list of @var{key}=@var{value} pairs separated by ':'.
@item drop_pkts_on_overflow @var{bool}
If set to 1 (true), in case the fifo queue fills up, packets will be dropped
rather than blocking the encoder. This makes it possible to continue streaming without
delaying the input, at the cost of omitting part of the stream. By default
this option is set to 0 (false), so in such cases the encoder will be blocked
until the muxer processes some of the packets and none of them is lost.
@item attempt_recovery @var{bool}
If failure occurs, attempt to recover the output. This is especially useful
when used with network output, since it makes it possible to restart streaming transparently.
By default this option is set to 0 (false).
@item max_recovery_attempts
Sets maximum number of successive unsuccessful recovery attempts after which
the output fails permanently. By default this option is set to 0 (unlimited).
@item recovery_wait_time @var{duration}
Waiting time before the next recovery attempt after previous unsuccessful
recovery attempt. Default value is 5 seconds.

If set to 0 (false), the real time is used when waiting for the recovery
attempt (i.e. the recovery will be attempted after at least
recovery_wait_time seconds).
If set to 1 (true), the time of the processed stream is taken into account
instead (i.e. the recovery will be attempted after at least @var{recovery_wait_time}
seconds of the stream is omitted).
By default, this option is set to 0 (false).
@item recover_any_error @var{bool}
If set to 1 (true), recovery will be attempted regardless of type of the error
causing the failure. By default this option is set to 0 (false) and in case of
