[FFmpeg-user] ffmpeg-2.1.1 latest - raw data decode/encode appears broken

[David Favor]

Maybe I completely misunderstand how to extract + inject data
streams into .VOB containers... Here's what I'm trying to do...

I have a .VOB file generated by the now dead Apple iDVD project.

This .VOB file contains three streams - simple audio + simple video...

And a dvd_nav_packet stream which is a complex, template based,
menu system to navigate to different points in the other .VOB files

I'd like to break apart this .VOB file into audio + video + data files.
Then edit the audio + video + reassemble the .VOB file with these three
files. Seems very simple.

My ffmpeg shows support for encode/decode of .data extensions... which
I take to mean, just extract + add some data, with no processing...
Maybe I'm wrong about this.

If I understand the ffmpeg stream mapping docs, the following syntax should strip
the first occurrence of audio + video + data streams into separate files...

This command works as expected - producing a .wav file + .vob file.

     ffmpeg -y -i VTS_01_0.VOB -c:a pcm_s16le -ar 44100 -ac 2 foo.wav -map 0:1 -c:v copy foo.vob

This command fails, which adds the data extract by adding -map 0:1 -c:d copy foo.data

     ffmpeg -y -i VTS_01_0.VOB -c:a pcm_s16le -ar 44100 -ac 2 foo.wav -map 0:1 -c:v copy foo.vob -map 0:1 -c:d copy foo.data
