You need a compiler, make and git. Iirc, all three are installed if you type something like "gcc -v" on the command line (but I assume they are now installed by brew). $ git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg $ cd ffmpeg $ ./configure && make ffmpeg This could for example fail if you don't have a new enough yasm or nasm binary, in that case please try "./configure --disable-yasm", feel free to add "--enable-gpl". If you know hat your cpu has - for example - four cores, you can use "make -j4 ffmpeg" to speed up compilation. This creates a current ffmpeg binary, please test (from the build directory) if it allows to reproduce your issue. Then edit libavformat/movenc.h and run "make ffmpeg" again to get a binary that allows testing if you found the actual issue.
