Each section ("chunk"? FOURCC....? Been a while...) should have the
section length stored somewhere. Parsing an AVI is a bit more complex
than just jumping to a specific offset. Removing a section is also a
bit more complex than just cutting it out. All the offsets in the AVI
will likely need to be updated. The task is not as simple as it seems
despite AVI being one of the simplest and most widely documented video
container formats. I'm assuming, of course, you still want the AVI to
still function properly in a video player after you are done massacring it.
