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 + Mahol. + + 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 + project. + + 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. -- 2.3.1 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
