Hi Everyone,
Thanks for your replies! I now have a first-pass solution working. Basically I iterate over the entire file, and count the number of times I get STATE_PICTURE from the mpeg2_parse function. This works, but it's horribly slow. A 24 minute clip (400 MB on disk) takes over a minute to parse (84 seconds). However, I notice that when I open the file in a media player (VLC for example), it displays the duration instantly. I was hoping someone here would know a few tricks to speed up this performance. One thing I have thought of is increasing the size of my memory buffer from 4KB to some larger value, but it doesn't seem to help that much (using 8KB reduces the time from 84 to 81 seconds). Is there something I'm missing? I can't help but feel that my algorithm is horribly naïve - there must be a better way to do this. Is this the best performance I can reasonably expect?
