On my desktop Ubuntu 10.4 I use ffmpeg to convert videos to a format my dvd-player understands. On my laptop running 10.10 I can't get the same command to work, what package(s) are missing?

ffmpeg -i infile.flv \
-threads 2 -vcodec mpeg4 -vtag divx -acodec libmp3lame \

Unknown encoder 'libmp3lame'

Using apt-cache search libmp3lame I'm told there exist libmp3lame0 and libmp3lame-dev, both of which I've installed. Using acodec libmp3lame0 doesn't work either.

Why didn't you sudo apt-get install libmp3lame0 ? – Marco Ceppi Nov 17 '10 at 22:07
@marco I did: "...both of which I've installed". – matt wilkie Nov 18 '10 at 2:06

sudo apt-get install ffmpeg libavcodec-extra-52

If package not found try:

sudo apt-get install ffmpeg libavcodec-extra-53

you can also try to install the libmp3lame0 package:

sudo apt-get install libmp3lame0

Try this, Open Synaptic Package Manager and reinstall ffmpeg. Also try installing winff in Synaptic, this will give you a GUI for ffmpeg. Edit... See also about adding "libavcodec-extra-52, libavutil-extra-49 and libavformat-extra-52 from the multiverse repository"
