What I'm trying to do - overall summary.
I'm trying to record tv shows using my computer, then extract the audio only and put it on my mp3 player.
I have an ATI-All in Wonder, a Windoze PC, and an archos jukebox.
What I know so far
I can set the AIW to record the show. I get many many choices for format.
I can make it an AVI, and tell it to use MPEG Layer III (not AAC).
I can make it an MPEG I or MPEG II and I assume it uses Mpeg I for audio, although I can't tell.
My Specific Question
What I need to know is if there is a command line tool to demux an AVI file when the audio encoded part of the file is already MP3? All I need is something to split it and then I'll be set. Of course, I'd like it to be command line so that I can script it and run it overnight.
Currently I'm doing this:
- record as what ATI calls mpeg 2.
- bbdmux nameoffile.mpg 0xc0 nameoffile.mp2
- lame nameoffile.mp2 nameoffile.mp3
- delete mpg, mp2, copy mp3 to device. etc...
What I'd like to do is take advantage of the fact that the ATI-AIW will record in mp3 and just do this"
- record as avi with mp3 encoded audio stream
- seperate the mp3
- delete, copy, etc...
Do any of you know if I can do this? I think ffmpeg might do it, but everything I've read seems to talk about converting from AAC to MP3. I'm already in MP3.
