I'm looking for a way to embed markers into a WAV, AVI, or MPG file.  On
playback, I want to generate an event each time a marker is accessed in the
data stream.  Basically, this will replace timing functions that use either
frame or time offset information to generate synchronized events.  It seems
to me that to avoid errors, this will require pre-parsing of the data file
stream to remove the markers before they get to the audio/video driver.  

Does anybody know of such a parser, or can you point me in a direction to
create one?

Thanks in advance.
