I've got a bunch of .mpg files that I've ripped directly from DVD's. I'm planning on batch-converting them all to DivX.... but.... I want to normalize their audio first.
If I can't find some Windows-based batch solution, I'll have to write some shell script in Linux for it... but I need to know what tools would be best to:
- Demux the .mpg file to video and audio
- Normalize the audio stream (as it came out of the .mpg file, or will I need to transcode it to AIFF, WAV, MP3, etc?) and then output it into a format which won't freak out the DivX6 encoder (or cause audio-sync problems) when it sees it muxed with the video.
- Remux the audio and video together (making use of any audio/video offset info generated by the demuxer).

For a windows app you can use demux - it works quite well and is a commandline tool

I've never used it myself, so I would be curious to read how you succeed, if you decide to try it.
