Comment (by petere):
When ffmpeg encodes a single large vob file it is fine but if I take
VTS_01_1.vob and combine it with VTS_01_2.vob, VTS_01_3.vob, VTS_01_4.vob
and VTS_01_5.vob using a file concatenation outside of ffmpeg then use
ffmpeg to try to read the duration it is wrong. If I call ffmpeg -i on
any of the vobs separately the duration and bitrate is correct. It seems
to only be an issue when using several vobs combined together.
