[FFmpeg-user] "ERROR: libx264 not found" Ubuntu 11.10

You can get sure if ffmpeg has been built with libx264 by this command :

ffmpeg -codecs | grep libx264

if the result wouldn't include something like this :

EV    libx264         libx264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10

it means your ffmpeg installation doesn't have x264 codecs.

I'm also new to this mailing list, may it's better to open a new
thread, however "unknown encoder: 'libx264" seems you haven't
installed ffmpeg with x264.
