Extracting audio segment from VOB

[asarian]

I'm trying to cut a video clip out of an old VOB. For the video itself, it was easy:

Trim(110773, 117522)

How do I get avisynth to extract that same segment from the audio track, though? (so I can mux the two later on) It's an ac3 track. The video output is going to x264, but how do I save the audio to file?

Thanks.

Use old good DGIndex.
yup.

Ah yes, forgot about that one. :) Thanks.

I got it to work using a makeshift solution with Adobe Premiere 5, creating a subclip (I used Adobe Premiere to determine the frame boundaries for Trim to begin with); then I was able to have Adobe Premiere export the audio of the subclip to Adobe Soundbooth, in which I could save it as a file.

You might find my MpegAutoIndexSource() function handy:

It automates the indexing and sourcing via DGIndex handles dubbing of the AC3 nicely (with options for downmixing to stereo, etc.)

Example:
MpegAutoIndexSource("foo.VOB", Downmix=true)
Trim(110773, 117522)
