最新版本号的ffmpeg 支持 libh265,可是还是0基础測试阶段
在linux 上安装ffmpeg 支持h265编码器依照下面步骤：
Anyhow here are the simple steps:
1. Make sure you have a current build of ffmpeg checked out of git along with any other libs you are using e.g. libx264
2. Download the libx265 repository and build as per the instructions here: https://bitbucket.org/multicoreware/x265/wiki/Home (note I assume no one still uses Windows for dev!)
hg clone https://bitbucket.org/multicoreware/x265 cd x265/build/linux ./make-Makefiles.bash make make install
3. On your ffmpeg configure it with –enable-libx265 (it is disabled by default). Sample from my configure below
./configure --prefix=/usr/local --enable-gpl --enable-nonfree --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxvid --enable-libvidstab --enable-libx265 make make install
我做測试的时候用的是windows系统，从官网下载最新版本号它就支持
ffmpeg -i d:\soft\720p.mp4 -c:v libx265 -b:v 2000k d:\soft\myvideo.mkv 測试视频 新警察故事2013 1280*720高清 540m(当中一部分)。转换后mkv文件 1280*720高清 313m

下一步考虑 h265 播放器。用rtmp 协议播放h265 视频，希望得到技术指导
