vobstripper is a program that copies a .VOB file from stdin to stdout, discarding subtitles and all but one AC3 audio channel.
This program does not adjust pointers and other information in the .VOB file to cleanly delete the discarded streams. However, the resulting .VOB files are acceptable for input to a program such as dvdauthor that expects to be responsible for filling in the VOBs.
Since vobstripper invalidates the pointers in the .VOB file, a .VOB file that is to be processed by both vobstripper and vobwalker must be processed by vobwalker first.
vobstripper is in the public domain (GPL license).
What's New in This Release:
· Multiple private stream 1 subchannels can be specified as keepers on the command line.
· Discards MPEG program stream end codes. I've seen several files on which tools like mpeg2dec and bbdmux silently stop before processing the entire file because of a rogue MPEG program stream end code embedded in the middle of the file.
· Slightly more sophisticated Makfile contributed by a user.
