Is there a way to batch demux/convert audio to 48 kHz?

[kylen]

I have a bunch of (S)VCDs I want to put onto DVD-Rs using the DVD-Patcher/no reencode method.

I was wondering if anyone knows of a way to use a command-line tool to list a bunch of MPEG files and have it go through and demux them and up-convert the audio to 48kHz.

Thanks!

I haven't done this specific task, but I do some similar batch-processing - I extract the audio from every MPEG2 in a directory to a WAV file. I use a .bat script to automate running bbdemux (part of bbtools) and besweet. In theory besweet should be able to take the audio directly out of the MPEG, but it didn't work when I tried it (I might have just done it wrong).

For my own convenience, I have one .bat file that just processes a single MPEG passed on the command line, and another .bat to run that in a loop over all .mpg files in the current directory.

demux.bat FILE.mpg

@echo off
bbdmux.exe %1 0xc0 %1.mp2
besweet.exe -core( -input %1.mp2 -output %1.wav -2ch )
del %1.mp2

demuxall.bat

@echo off
for %%f in (*.mpg) do demux.bat %%f

You'll want to either give the full path to the exe/bat files or make sure they're in your path. For converting to to 48kHz you'd use the ssrc plugin to besweet, by adding "-ssrc( --rate 48000 )" (I think, check the documentation) to the besweet command line.

TMPEG has a batch feature that works well!

Thanks sterno--that should give me a good start--I will just need to look up the command line args for besweet to convert to 48kHz.

coda304--The problem with TMPEG is that you need to use the GUI--I am looking for a command-line option.

Thanks,

Where can I find bbtools?
The site is now down and I cannot seem to find a mirror download.

svcd2dvdmpg free version will do just that for you.
