Tuxedo,

Glad you like the program.
I'd also like it to support more formats but unfortunatly it's built
upon SDL and the SMPEG library which only supports mpeg-1.  I looked
at the avcodec.library but I can't find any good documentation for
it and it would require me to start from scratch.

REALLY nice prog!
Just an idea...
I wasnt possible to use it with avcodec.library to support more file types?

Version 1.1 fixes the speed problem mentioned below. It's now slightly faster
than the original dumpmpeg program.

Oh ya, I just remembered I compiled the code with the gdb debugger options and
no optimization. I'll have a go at a re-compile and it should help the speed
issue.

Mpegit is slower than DumpMPEG due at least partially to the fact that you can
now specify a stop frame and I made the choice to make sure the stop frame gets
dumped. You probably are noticing most of the slow down on the last frame
captured. This is becuase it's not possible to step backwards through the mpg
file using the SMPEG library I think what it is having to do is rewind and
search for the last frame. If the stop frame is an even multiple of the skip
frame then you shouldn't see the big slowdown.  I'll take a look at the
algorithm when I get a chance and see if I can speed this up.

Thanks for the input.
