Batch multiplexing/ demultiplexing?

[festi]

Does anyone know of a program that does this that isn't a professional and crazy expensive tool? I've been searching around for a batch multiplexer because my video project has multiple mpeg-2 files that need to be de-multiplexed, have the volume normalized, and then be multiplexed with the normalized audio. I use a batch converter for the .mp2 audio normalization, but using tmpgenc mpeg tools to (de)multiplex each file is time consuming and repetitive. Any suggestions would be appreciated.

I know of a great demuxing program that unfortunately isn't a batch, but it is much faster than the one in TMPGENC, and its free. Its on Ted Rossin's site here:

You could also pm Trossin and ask him if he could write a batch version for you. The program is called demux. Its command line but easy to use, just copy demux.exe to the folder with your mpeg files. Then start a command prompt by going to start, run, and then typing either command or cmd depending on your version of windows. In the prompt, type: cd C:\documents and settings\ <-- your directory of the folder and then hit enter. This should change the directory to that folder. then type: demux.exe and hit enter. This will bring up some instructions for demux. Then type: demux.exe yourmpegfilename.mpg outputfilename and hit enter. It will then demux your file. I hope this works for you!

If you have a command line tool, just write a batch file and create it in the same directory as demux.exe.

All you need is demux.exe yourmpegfilename.mpg outputfilename on each line. Then double-click the batch file.

Yes, i was going to suggest this tool too, in combination with a .bat script. An alternative is mpgtx that has a host of other features.
To mux, there's mplex from mjpeg tools (see DVDAuthorGUI for Windows cygwin builds) that similarly can be called from a batch file.

demux is a faster version of bbdmux, part of bbtools. You can just do a google search for bbtools.

Thanks for your replies. I'll write a bat file for the command line program, because this seems like the best option. Thanks again everyone-- this will save me a lot of time doing repetitive demuxing.
