what is the format of AVI programs?

[Brit]

I am working on a program to organize my collection, and am trying to write a program that will pull out vital details from each media type I am cataloging.

I found a library for pulling mp3 tags, and am currently working on AVIs. I found some infomation, and can pull out the screen size, frames per second, and legth of the avi, but I am having difficulty getting the kbps (actual or average when using variable rates).

I can calculate a rough kbps for both audio and video by dividing the size of the file by the time, bu tI am hoping for something better.

Once I get the AVIs working, then I plan on tackling VOBs, MPGs and RMs.

thanks

Gspot has a command line option /x . This writes a small TXT file containing info on most mutimedia formats. here's an example:

AVI File Details
========================================
Name.........: movie.avi
Filesize.....: 351 MB (or 359,860 KB or 368,496,640 bytes)
Runtime......: 00:41:41 (59,966 fr)
Video Codec..: XviD
Video Bitrate: 1049 kb/s
Audio Codec..: 0x0055(MP3) ID'd as MPEG-1 Layer 3
Audio Bitrate: 121 kb/s (60/ch, stereo) VBR LAME3.90.°
Frame Size...: 640x352 (1.82:1) [=20:11]

It shouldn't be too difficult for a program to parse the info...
