It sounds like mpeg4videoparse, then - better to use a well tested
existing plugin than a custom one.
However, that won't cause a crash by itself.

None of this is the cause of your crash. Your crash is simply a bug in
your plugin - and without the source to your plugin, or even any
details about where it's crashing, there's no possible way we can help
you any more than that. Good luck with your debugging!
