AVI file size limitation and unintended video segmentation

[dongyunwang]

When using the software, I've encountered an issue where AVI files have a maximum size limit of 100,000 units (exact measurement unclear). Even when explicitly setting the limit to 100,0000,

the software fails to save long continuous recordings properly. Instead, videos get split into small segments of several dozen KB each, despite my DV device recording continuously.

by the way Thank you so much for maintaining this project. Your work is truly appreciated! If I ever get the chance, I'd love to buy you a coffee - your program has been incredibly helpful and has made my work much easier.

This is likely the result of the following line of code:

// CaptureCfg.cpp:45
DDV_MinMaxUInt(pDX, m_maxAVIFrames, 10, 1000000);

I don't know enough about the AVI file format to know if this is a limitation of the file format or is simply an arbitrary value chosen by the author, but it's a start.

Edit: It seems like the frame count in an AVI file is an unsigned 32-bit integer, so it may be possible to raise the limit from 1000000 to 4294967295 (a bit more than a 4000x increase).
