An faster equivalent that does not involve git is: $ curl -O http://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2 $ tar xf ffmpeg-snapshot-git.tar.bz2 > $ 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. > > Carl Eugen _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
