I think I have done something, but I can't tell what exactly... Now, my Ubuntu doesn't want to decode MPEG-4 and H.264 video-files (files extensions
vlc still works (of course, it has built-in codecs) but
totem and the thumbnailer stopped working.
Here's what I did recently that might be related :
sudo apt-get install libvo-aacenc-dev libx264-dev libtheora-dev librtmp-dev libvorbis-dev libfdk-aac-dev libmp3lame-dev libfaac-dev libpulse-dev libxvidcore-dev
I used them to build
libav-toolsfrom GIT. Now
libavworks like a charm, and that makes me think that my
libx264 is fine (which is, I think, used to decode H.264 and MPEG-4).
I have this error message :
$ ▶ totem video.mp4 ** Message: Missing plugin: gstreamer|1.0|totem|H.264 decoder|decoder-video/x-h264, stream-format=(string)avc, alignment=(string)au, level=(string)3.2, profile=(string)main, parsed=(boolean)true (H.264 decoder)
Can you help me ?
