[Ffmpeg-devel] VOB input is producing major problems.

Hi,

I have a VOB file which is the beginning of a TitleSet from a commercial
DVD. It plays fine in Media Player Classic and WMP etc. It would seem that
the latest SVN revision (and many of the previous builds I have tried) has a
problem with it right from the initial probe.

I am actually trying to remux it so am trying:

ffmpeg -i VTS_04_1.VOB -target dvd -vcodec copy -acodec copy TEST.mpg

Which produces a completely garbled mpeg.

But also when trying a re-encode i get different errors/warning from ffmpeg
but the resultant mpeg is just the same mess.

The vob is on ftp://ftp.mplayerhq.hu/MPlayer/incoming/VOB_seems_damaged

Any ideas?

Thanks in advance,

Chris


Here are the outputs from the two runs:




ffmpeg -i VTS_04_1.VOB -target dvd -vcodec copy -acodec copy TEST.mpg
