[FFmpeg-devel] ffmpeg latest git, extracting data streams seem broken

[David Favor]

I just trying to extract a data stream for later use.

Seems like this use to work.

My question, is this a bug or have I just screwed up
the data stream extract syntax.

I've asked about this on the user list. No clear answer.

Thanks.

I'm trying to extract stream #0:0 into a file for later use.

The command which I seem to remember using was something like this,
which now produces an error, which seems to be trying a conversion
of the data stream to a DTS audio stream...

ffmpeg -y -i VTS_01_0.VOB -map 0:0 -c:d copy -f data foo.data
