Program advice

[Razorblade2000]

I want to create myself a shell scrip that is capable of:
Ripping (vobcopy till now)
Encoding the vib files to MPEG 4 (mencoder)
Encoding 2 audio streams to MP3 (2*mencoder -> avidemux2)
Ripping the subtitles (nothing yet)
Multiplex 1 avi and 2 mp3 --> 1 final avi (avidemux2)

Now my questions:
1.Is there a quicker/more direct way than "2 times Mencoder to avi -> extract 2 MP3s via avidemux2 -> mux 2 mp3s and 1 video.avi to a final avi"?
2.Can mencoder handle 2 audio streams directly?
3.Any application that can do vob->srt?
4.Any application that can split avis via commandline?
5.Is there a better substitute for vobcopy that will support splitting vob files? (I still work on fat32...)
6.Is there an app that can mux an avi file with 2 audio streams via commandline?
thx in advance :D

edit:
just found out about the "dumpstream" param of mplayer... seems as if this could solve my problems 1 and 5... Now I only have to do some research on how to use this param

Actually the MPlayer devs advise against concatonating vobs through a pipe into mencoder.

These are the two advised methods to endode from a dvd on the hard drive.

either rip the whole dvd with dvdbackup and use mencoder like this:

mencoder -dvd-device /path/to/ripped/dvd dvd://1

or rip the dvd w mplayer to one big vob.

mplayer -dumpstream dvd://1

and

mencoder stream.dump

thx...
I guess I'll kick windows and use reiserfs (so I can get >4gb files to work :D)

for multiple audio tracks in a matroska container you could do something like this.

mplayer -aid 128 --ao pcm -aofile english.wav -vo null -vc dummy stream.dump

mplayer -aid 129 --ao pcm -aofile french.wav -vo null -vc dummy stream.dump

oggenc -q3 -o english.ogg english.wav
oggenc -q3 -o french.ogg french.wav

Use these file sizes to determine your video bitrate and encode with the -aoc copy option. (you'll drop this audio in the muxing process.)

now mux your video.

mkvmerge -A movie.avi --language en english.ogg --language fr french.ogg

btw: Matroska also supports muxing of vobsubs directly

The man page for mkvmerge goes into how to produce srt subs on the command line using subtitle2pgm

I'll have to stick with avi, as my standalone doesn't support matroska (yet :D)
