FFMPEG and H264 encode mp4

Question

I tried to encode a video mov to mp4 width h264 codec but I get this error :

Unknown encoder 'libx264'

But when I check if h264 if supported by my config I saw it does :

DVD h264 H.264 / AVC / MPG-4 AVC/ MPEG-4 part 10

and my code :

FFMPEG -y -i video.mov -vcodec h264 video.mp4 ;

Can someone help me with this ? Thanks.

Run ffmpeg -codecs; it will list all the supported codecs, and make sure you have libx264 which is the name of the H.264 encoder. The decoder in ffmpeg is named h264.

If you are compiling ffmpeg you need to compile and install x264 and then compile ffmpeg using compile options --enable-gpl --enable-libx264. See Compile FFmpeg on Ubuntu Hardy Heron or How to quickly compile libx264. Alternatively, you can use an already compiled static build.
