Bug Description

Binary package hint: ffmpeg2theora

When I converted a mp4 file made by Nokia N95 8GB (ISO Media, MPEG v4 system, version 2), the output file did not work with MPlayer, VLC or kaffeine. On mplayer, the video was played with 10x speed and it did not work at all with VLC or kaffeine.

I did not use any switches for ffmpeg2theora. Just a simple conversion.

The video clip is available at: http://antti.laiti.fi/galleria/albums/miro/a_1v/22092007.mp4

Your file uses the mp4a audio codec. mp4a can't be distributed for free in Ubuntu, see:
http://en.wikipedia.org/wiki/Mp4a#Licensing_and_patents

Please let the content provider know about this problem, and encourage them to encode in formats that don' t have such problems, or to provide Ogg Theora + Ogg Vorbis encoded content additional to their current content.

Okay, thanks for the comment!

I recall I have earlier been able to encode those videos but I must have had a non-free version of ffmpeg then.

Seems that this is working now with Ibex (0.21-0.1build1). Or could it be that I tested it now with 32-bit system? The original error was with x64_86,
