@WarpEnterprises:

Thank you for the new version!
I've been trying it out with some more uncompressed Quicktime files now and noticed a strange behaviour. It works rather well but I can only use files with 5093 frames (720x576) or less.

The index file from Yuvscan has these values:
frame 5068:4242944000
frame 5094:4264710144
frame 5120:4286476288

Using the "show" parameter the byte position for frame 5093 is 4 263 680 000 (image), and the byte position for frame 5094 is -30 257 152 (image).
There seems to be an integer overflow somewhere. Would you mind looking that up (Im too novice to find the error in the source)?
thank you!
