Split AVI

[niol1000]

Hi All,

I'm doing some research into writing an application to split (and maybe join) AVI files using c++. I'm a newbie when it comes to media programming but I have done some initial research into the AVI format. As I understand I need to rewrite the header and index in the first part of the file and i the following I need to insert a new header and index.

I can "steal" a lot of the information from the original AVI header a and use it when rewriting, but I have a few questions:

I need a way to recognize frames as I need to count them, how can I recognize a individual frame?

Also when it come's to creating the index I'm a bit lost, can someone explain for me how it works and how I can create the index?

All comments and help are welcome!

PS Of course I will release the code as open source so all can benefit from it.

Usually all frames start with track# concat with wb, dc, db, dd which are for audio, video, protected audio/video, etc
