[MPlayer-users] Filtering audio with -dumpstream?

[matthew.garman at gmail.com]

As discussed recently on this list, if I do this:

    mplayer dvd://1 -dumpstream -dumpfile dump.vob

I get all of title 1 minus the IFO.

Is is possible to filter what actually gets dumped?  E.g., say I
only want the English audio track:

    mplayer dvd://1 -alang en -dumpstream -dumpfile dump.vob

or even

    mplayer dvd://1 -aid 128 -dumpstream -dumpfile dump.vob

(where 128=english audio)

The above commands still result in a VOB file that has *all* audio
tracks.

Thanks,
Matt
