A little batch NSV converter (to vcd)

[PavalloKazzo]

I wrote this script these days for help me converting a huge amount of nsv files.
Some limitations:
- It will process nsv files in subdir like dir/subdir/*.nsv (this is because the way streamripper save files);
- it also needs to have a workdir (that you will pass on script startup) so /workdir/dir1/anyname/*.nsv /workdir/dir2/anyname/*.nsv and it will produce /workdir/final_mpg_files/dir1.mpg /workdir/final_mpg_files/dir2.mpg
- It use mplayer, mpgtx (wine and faad for the "demuxer version") tools: need to be installed
- Don't place any other dir except the ones with nsv files cause they will be processed
- Absolutly don't call dir with numbers cause will loop mpgtx creating huge log files

I made two version: one simple (nsv--->mencoder-->mpgtx--->final_mpeg) and other a little ore complex (nsv-->NSVD.exe--->faad--->mencoder-->mpgtx--->final_mpeg) the "demuxer version"
This last because I couldn't get mplayer work with AAC on Debian (now I'm on Fedora 4 and seems ok) so Debian users could try that if their mplayer can't handle AAC

Some known bugs:
- If an nsv file got some corrupted frames this will cause an a/v desync plus the cut of a piece of the stream cause mplayer will do these:
Stream corrupted:
- - - - - - V4 V5 V6 V7 V8
A1A2A3 A4 A5 A6 A7 A8
Resultant mpg files:
V4 V5 V6 V7 V8
A1 A2 A3 A4 A5
if anyone knows how to resolve this is welcome
- Also if someone could please post a good tool to join two+ mpeg files cause mpgtx seems to cause problems (I heard about using I/O redirection aka cat aka <> but could you assure me it will work?); this could be a way to resolve any type of problems derived from bad nsv files, just run the split command to divide nsv files in 512kb or 1 mb chunk each!!!

By now I think it's all

P.S. rename the file from zip to gz
P.P.S Some Spam for google: nvs mplayer vcd svcd xvcd xsvcd dvd nsvd.exe linux

Ok I need some help with mencoder
Seems like it can't manage to make vcd compliant files...
Any help? What about dvds?
