Create a batch file to demux all these mpeg-2s at once

[Garibaldi]

I would like to use Demux (demux.exe) to demultiplex many mpg2s that I have here. I've tried projectx but unfortunately it results in jumpy video and audio for whatever reason. Is there a way I could create a batch file (.bat) for demux, so I can run all my files at one time? Also is there a way to run files with a space in the filename?

Thanks

i don't see why you shouldn't be able to make a .bat file. Are you familiar with how to do this? if you are then skip the next section:

1) you might want to copy the mpeg files you are wanting to demux to the same folder as demux just to make things easier..if not we'll handle that as well.
2) Open notepad and just start typing dos commands. You'll want to do something like:

cd\
c:
cd movies
demux (source file) (destination file)
demux (new source file) (new destination file)
...and so on and so forth.
once you have the commands in a text file then go to file/save as, give it a name with a .bat extension and save the file type as all files. you now have a .bat file. to edit just right click on it and go to edit

if you know how to make .bat files and just are curious about the spaces, all you have to do is put quotes around what has the spaces in it. for instance, lets say you want to copy something to c:\my files\todays files
you would have to do:

copy (something) "c:\my files\todays files\"

hope this helps.

you might take a look at batchdemux, which can be found on the download page on the link below. It creates a bat file, using demux or mpegtx, depending on the users selections.

That helps a lot!!! Thanks for the quick reply!!! I wasn't sure if there was any syntax formatting to dos files. In this case I should be able to do all of them relatively easily. Thanks!

Also I just tried demuxing one of the mpg2s as a test with demux and the outputted .m2v sits at the first frame of the video - it just freezes there for the entire duration of the video. Any ideas on why this is happening and how to fix it?

im not really sure. you might try playing it in dgindex, or vlc to make sure its not just your mpeg decoder. You might also try using mpgtx to see if it yields better results.

I tried mpgtx - same result. Its just the same frame throughout, but the mpg itself plays fine so I don't know what's going on. When I use projectx the demuxed version plays fine but it jitters - skips.
