Public bug reported:
Ubuntu Intrepid, updated to 2008-02-03
ffmpeg no longer supports AMR NB or WB. Under Hardy, it used to. The
codec seems to be disabled.
$ ffmpeg -i MVI_0002.3GP -ar 44100 MVI_0002.mp4

I have installed
* ffmpeg 3:0.svn20080206-12ubuntu3 from main
* libavcodec-unstripped-51 3:0.svn20080206-12ubuntu3+unstripped5 from
multiverse.
I do not have a copy of the result under Hardy. I can upload an example
video if necessary, but it probably just needs to be enabled in the
build.
It would be wonderful to get AMR_NB decode back again so that I can
transcode videos from my phone...
