Merging Video or Audio mpeg streams via DOS copy command?

[Airr]

I've successfully de-muxed two vcd mpg files from a two-cd-movie set into their respective video and audio streams.

I'd like to combine them using a command-line, so that i can script the process.

Would using the DOS copy command in binary mode (copy /b) allow me to successfully (meaning without issues like sync probs) merge the seperate audio/video streams?

I have played with this, and re-muxed the merged streams into a single huge mpg file; it played normally in media player and PowerDVD.

Just wondering if there are any inherent issues with doing it this way?

Thx!

Your method will cause constant hard disk seeking during playback, and also won't work if you want to use the video for any sort of CD or DVD based playing, since those normally can't be seeked fast enough, plus I'm pretty certain that the specs require an interleaved stream for standard DVDs. They certainly do for VCDs and SVCDs.

Rats.

It worked, up to a point. The combined video file only showed the length of the first file (49min vs 151min for the total length) and would only play up to that point.

Do you know of any utils that would rescan the file and re-write the headers?

Still, a usefull attempt! At least I can script the joining and transcoding of the audio.... And the extraction of the video streams from the bin/cue files.

I'll just join the vid streams in maestro....like I should have done from the begining!!!

Thanks for your reply, Tearex!
