+              │ RELEASE NOTES for FFmpeg 2.6 "Grothendieck" │
+              └─────────────────────────────────────────────┘
+
+   The FFmpeg Project proudly presents FFmpeg 2.6 "Grothendieck", about 3
+   months after the release of FFmpeg 2.5.
+
+   A lot of important work got in this time, so let's start talking about what
+   we like to brag the most about: features.
+
+   A lot of people will probably be happy to hear that we now have support for
+   NVENC — the Nvidia Video Encoder interface for H.264 encoding — thanks to
+   Timo Rothenpieler, with some little help from NVIDIA and Philip Langdale.
+
+   People in the broadcasting industry might also be interested in the first
+   steps of closed captions support with the introduction of a decoder by
+   Anshul Maheswhwari.
+
+   Regarding filters love, we improved and added many. We could talk about the
+   10-bit support in spp, but maybe it's more important to mention the addition
+   of colorlevels (yet another color handling filter), tblend (allowing you
+   to for example run a diff between successive frames of a video stream), or
+   eventually the dcshift audio filter.
+
+   There is also two other important filters landing in libavfilter: palettegen
+   and paletteuse, submitted by the Stupeflix company. These filters will be
+   very useful in case you are looking for creating high quality GIF, a format
+   that still bravely fights annihilation in 2015.
+
+   There are many other features, but let's follow-up on one big cleanup
+   achievement: the libmpcodecs (MPlayer filters) wrapper is finally dead. The
+   last remaining filters (softpulldown/repeatfields, eq*, and various
+   postprocessing filters) were ported by Arwa Arif (OPW student) and Paul B
+   Mahol.
+
+   Concerning API changes, not much things to mention. Though, the introduction
+   of devices inputs and outputs listing by Lukasz Marek is a notable addition
+   (try ffmpeg -sources or ffmpeg -sinks for an example of the usage). As
+   usual, see doc/APIchanges for more information.
+
+   Now let's talk about optimizations. Ronald S. Bultje made the VP9 decoder
+   usable on x86 32-bit systems and pre-ssse3 CPUs like Phenom (even dual core
+   Athlons can play 1080p 30fps VP9 content now), so we now secretly hope for
+   Google and Mozilla to use ffvp9 instead of libvpx.
+
+   But VP9 is not the center of attention anymore, and HEVC/H.265 is also
+   getting many improvements, which includes optimizations, both in C and x86
+   ASM, mainly from James Almer, Christophe Gisquet and Pierre-Edouard Lepere.
+
+   Even though we had many x86 contributions, it is not the only architecture
+   getting some love, with Seppo Tomperi adding ARM NEON optimizations to the
+   HEVC stack, and James Cowgill adding MIPS64 assembly for all kind of audio
+   processing code in libavcodec.
+
+   And finally, Michael Niedermayer is still fixing many bugs, dealing with
+   most of the boring work such as making releases, applying tons of
+   contributors patches, and daily merging the changes from the Libav project.
+
+   A more complete Changelog is available at the root of the project, and the
+   complete Git history on http://source.ffmpeg.org.
+
+   We hope you will like this release as much as we enjoyed working on it, and
+   as usual, if you have any question about it, or any FFmpeg related topic,
+   feel free to join us on the #ffmpeg IRC channel (on irc.freenode.net) or ask
+   on the mailing-lists.

-  "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.

+@item faac
+FAAC-inspired method.
+
+This method is a simplified reimplementation of the method used in FAAC, which
+sets thresholds proportional to the band energies, and then decreases all the
+thresholds with quantizer steps to find the appropriate quantization with
+distortion below threshold band by band.
+
+The quality of this method is comparable to the two loop searching method
+described below, but somewhat a little better and slower.
+
+@item anmr
+Average noise to mask ratio (ANMR) trellis-based solution.
+
+This has a theoretic best quality out of all the coding methods, but at the
+cost of the slowest speed.
+
 @item twoloop
 Two loop searching (TLS) method.
 
 This method first sets quantizers depending on band thresholds and then tries
 to find an optimal combination by adding or subtracting a specific value from
 all quantizers and adjusting some individual quantizer a little.
-Will tune itself based on whether aac_is/aac_ms/aac_pns are enabled.
-This is the default choice for a coder.
 
-@item anmr
+This method produces similar quality with the FAAC method and is the default.
-Average noise to mask ratio (ANMR) trellis-based solution.
-
-This is an experimental coder which currently produces a lower quality, is more
-unstable and is slower than the default twoloop coder but has potential.
-Currently has no support for the @option{aac_is} or @option{aac_pns} options.
-Not currently recommended.
 
 @item fast
 Constant quantizer method.
 
 This method sets a constant quantizer for all bands. This is the fastest of all
-the methods and has no rate control or support for @option{aac_is} or
+the methods, yet produces the worst quality.
-@option{aac_pns}.
-Not recommended.
 
 @end table
 
-@item aac_ms
-Sets mid/side coding mode. The default value of auto will automatically use
-M/S with bands which will benefit from such coding. Can be forced for all bands
-using the value "enable", which is mainly useful for debugging or disabled using
-"disable".
-
-@item aac_is
-Sets intensity stereo coding tool usage. By default, it's enabled and will
-automatically toggle IS for similar pairs of stereo bands if it's benefitial.
-Can be disabled for debugging by setting the value to "disable".
-
-@item aac_pns
-Uses perceptual noise substitution to replace low entropy high frequency bands
-with imperceivable white noise during the decoding process. By default, it's
-enabled, but can be disabled for debugging purposes by using "disable".
-
-@item aac_tns
-Enables the use of a multitap FIR filter which spans through the high frequency
-bands to hide quantization noise during the encoding process and is reverted
-by the decoder. As well as decreasing unpleasant artifacts in the high range
-this also reduces the entropy in the high bands and allows for more bits to
-be used by the mid-low bands. By default it's enabled but can be disabled for
-debugging by setting the option to "disable".
-
-@item aac_ltp
-Enables the use of the long term prediction extension which increases coding
-efficiency in very low bandwidth situations such as encoding of voice or
-solo piano music by extending constant harmonic peaks in bands throughout
-frames. This option is implied by profile:a aac_low and is incompatible with
-aac_pred. Use in conjunction with @option{-ar} to decrease the samplerate.
-
-@item aac_pred
-Enables the use of a more traditional style of prediction where the spectral
-coefficients transmitted are replaced by the difference of the current
-coefficients minus the previous "predicted" coefficients. In theory and sometimes
-in practice this can improve quality for low to mid bitrate audio.
-This option implies the aac_main profile and is incompatible with aac_ltp.
-
-@item profile
-Sets the encoding profile, possible values:
-
-@table @samp
-@item aac_low
-The default, AAC "Low-complexity" profile. Is the most compatible and produces
-decent quality.
-
-@item mpeg2_aac_low
-Equivalent to -profile:a aac_low -aac_pns 0. PNS was introduced with the MPEG4
-specifications.

-Long term prediction profile, is enabled by and will enable the aac_ltp option.
-Introduced in MPEG4.

-inputs. Should increase compression with interlaced content as it splits the
-fields and encodes each separately.
-
-@item wavelet_depth
-Sets the total amount of wavelet transforms to apply, between 1 and 5 (default).
-Lower values reduce compression and quality. Less capable decoders may not be
-able to handle values of @option{wavelet_depth} over 3.
-
-@item wavelet_type
-Sets the transform type. Currently only @var{5_3} (LeGall) and @var{9_7}
-(Deslauriers-Dubuc)
-are implemented, with 9_7 being the one with better compression and thus
-is the default.
-
-@item slice_width
-@item slice_height
-Sets the slice size for each slice. Larger values result in better compression.
-For compatibility with other more limited decoders use @option{slice_width} of
-32 and @option{slice_height} of 8.
-
-@item tolerance
-Sets the undershoot tolerance of the rate control system in percent. This is
-to prevent an expensive search from being run.
-
-@item qm
-Sets the quantization matrix preset to use by default or when @option{wavelet_depth}
-is set to 5
-@itemize @minus
-@item
-@var{default}
-Uses the default quantization matrix from the specifications, extended with
-values for the fifth level. This provides a good balance between keeping detail
-and omitting artifacts.
-
-@item
-@var{flat}
-Use a completely zeroed out quantization matrix. This increases PSNR but might
-reduce perception. Use in bogus benchmarks.
-
-@item
-@var{color}
-Reduces detail but attempts to preserve color at extremely low bitrates.
