This weekend I experimented a little with re-encoding video as H.265/HEVC, now that the codec has good support on both hardware and in Mac OS/iOS. sudo apt-get install mercurial cmake cmake-curses-gui build-essential disable-cli -disable-ffms -disable-gpac -disable-lavf configure -enable-static -disable-opencl -disable-avs x265 is under the GNU Public License Version 2 or later (see for details), you must upgrade FFmpeg’s license to GPL in order to use it. Then pass –enable-libx265 to configure to enable it. ![]() There is currently no native decoder, so libcodec2 must be used for decoding. Go to and follow the instructions for installing the library. FFmpeg can make use of the codec2 library for codec2 decoding and encoding. 官方说明Įxternal libraries x265 FFmpeg can make use of the x265 library for HEVC encoding. Update: FFmpeg has HEVC encoding support using MulticoreWare libx265 now. When you configure your FFmpeg build, all the supported native. Using patched FFmpeg with Chinese x265 support. Decoders are configured elements in FFmpeg which allow the decoding of multimedia streams. Using standalone Chinese x265 then mux the resulting file with FFmpeg. ![]() This means with the latest Zeranoe build you can now do this: ffmpeg -i INPUT -x265-params crf=25 OUT.mov Using standalone MulticoreWare x265 and then mux the resulting file with FFmpeg. Anyways, these are a complete set of current possibilities of encoding HEVC in order of my recommendation: Directly using MulticoreWare libx265 with FFmpeg. Although the former started out first, it is practically dead now, and the latter is under active development and is supported by VideoLAN (the developer of x264). To make matters more confusing, there are two independent projects both named “x265”, one by a Chinese college student and is practically dead, and another by a commercial company called MulticoreWare. Of course you can still use some patched FFmpeg build, but it is not recommended. Now you can use ffmpeg directly to encode HEVC or use another encoder than manually mux that into. ![]()
