+ │ RELEASE NOTES for FFmpeg 2.6 "Grothendieck" │
+ The FFmpeg Project proudly presents FFmpeg 2.6 "Grothendieck".
+ 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
+ the 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.
+ 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 now let's follow-up on one big cleanup
+ achievement: 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
+ Concerning API changes, not much things to mention. Thought, the
+ introduction of devices inputs and outputs listing is a notable addition
+ (try ffmpeg -sources or ffmpeg -sinks for an example of usage). See
+ doc/APIchanges for more information.
+ Now let's talk about optimizations. Ronald S. Bultje made the VP9 codec
+ usable on x86 32-bit systems and pre-ssse3 CPUs like Phenom (even dual core
+ Athlons can run 1080p 30fps VP9 content now), so we now secretely hope for
+ Google and Mozilla to use ffvp9 instead of libvpx.
+ But VP9 is not the center of attention anymore, and HEVC is also getting
+ many improvements, which includes optimizations, both in C and x86 ASM,
+ mainly from James Almer and Christophe Gisquet.
+ And finally, our Supreme Leader 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
+ A more complete Changelog is available at the root of the project, and the
+ complete Git history on http://source.ffmpeg.org.
+ As usual, if you have any question on this release 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.
