This document is a list of errors that can be returned by media drivers,
with a focus on what those errors mean in the media context.  What is
the point of stuffing it full of error numbers that media drivers will
never return, along with generic, one-line descriptions?  I'll defer to
the media folks on this, but I don't think this helps their users.

Thanks,
