整理一下 编码、解码库
VP9 is an open and royalty free[3] video coding format developed by Google. VP9 had earlier development names of Next Gen Open Video (NGOV) and VP-Next. VP9 is a successor to VP8. Its own successor, VP10, is currently under development. Chromium, Chrome, Firefox, and Opera support playing VP9 video format in the HTML5 video tag.
vp10还是草案

Software using libde265
http://www.libde265.org
Libde265 has been integrated into these applications:
-
gstreamer plugin, source, binary packages.
-
VLC plugin source, binary packages.
-
Windows DirectShow filters, https://github.com/strukturag/LAVFilters/releases
-
ffmpeg fork, https://github.com/farindk/ffmpeg
-
ffmpeg decoder source
用libde265解码的CPU使用率,有点高, 如果 ARMv7 (没有SSE 指令集) 能降低到 30fps 5~10% 就好了。(这方面的话,因为分块也更细了,所以可能不是那么容易办到)
Resolution avg. fps CPU usage
720p 284 fps 39%
1080p 150 fps 45%
4K 36 fps 56%
Environment:
- Intel(R) Core(TM) i7-2700K CPU @ 3.50GHz (4 physical CPU cores)
- Ubuntu 12.04, 64bit
- GStreamer 0.10.36

Video/Audio
ffmpeg
http://ffmpeg.org/
mp4v2
https://code.google.com/p/mp4v2/
## audio
faad http://www.audiocoding.com/
SimplE Lossless Audio https://github.com/sahaRatul/sela
都支持unix like + windows
ffmpeg里面的doc弄的比较好,将来听说vp9的速度比google的还快,期待中,以后没有新的视频压缩格式出现,vp9肯定在4K称霸。(强烈推荐)
mp4v2 linux编译全都OK,windows 居然缺头文件。。。好吧,只能从SVN 中下。文档也有点少,感觉用着很蛋疼,无从下手。。(关于mp4操作都宁愿用ffmpeg)
faad 可以解码aac音频格式,
其他的还有g711,g72X
还有adpcm
