Agreed.

Alright.

In this case, the trak type is 'rtsp', so I guess we can check if it starts
with 'rtsp'

This is on a trak, so there is nothing restricting it on
appearing with other 'normal' traks, or having multiple
rtsp traks together. I guess we should have a different message
to signal this. Something like an 'external-location' or 'external-content'.

Already answered.

Don't know, it is all zeroes in this sample.


I had never seen files like this before, but quicktime plays it fine. (Well,
the rtsp seems to
be inaccessible/down right now, but it does a redirect).
