See the FFmpeg Download page for links to builds for Linux, macOS, and Windows. However, this will have much less of an impact than choosing a faster preset for H.264 video encoding, and the audio quality will probably be reduced when compared to omitting -aac_coder fast. You can encode AAC audio faster using the -aac_coder fast option when using the native FFmpeg AAC encoder ( -c:a aac). If these configure options are used then encoding will be much slower. Related to the above suggestion, but make sure your ffmpeg was not configured with -disable-asm, -disable-inline-asm, and/or -disable-yasm.Īlso, make sure your x264 that is linked to ffmpeg is not compiled with -disable-asm. Your x264 is likely misconfigured and you'll need to get a new one or re-compile. If it shows none then encoding speed will suffer. When encoding via libx264 the console output should show something like: using cpu capabilities: MMX2 SSE2Fast SSSE3 SSE4.2 AVX You can easily switch between targets (examples) to build and execute. Now the project should be imported into CLion. Select the root CMakeLists.txt of this project. Example: ffmpeg -i input.wmv -preset fast output.mp4Ĭheck that the encoder is actually using the capabilities of your CPU. This is pretty simple: Make 'Open' or 'Open or Import' action. Current presets in descending order of speed are: ultrafast, superfast, veryfast, faster, fast, medium, slow, slower, veryslow, placebo.
A preset is a set of options that gives a speed vs compression efficiency tradeoff.
