I tried to export a movie from its original container (Quicktime) to Matroska, but mmg gives me these errors:
Warning: Quicktime/MP4 reader: Unknown/unsupported FourCC 'XVID' for track 1.
Warning: Quicktime/MP4 reader: Unknown/unsupported FourCC 'OggV' for track 2.
Warning: 'Test-1.mov': No tracks will be copied from this file. This usually indicates a mistake in the command line.
What should I do to be able to store an XVID video track and an a Vorbis audio track inside a Matroska container ?
