I've got a pretty big problem with streaming QT movies off Darwin - every
single movie I have tried streams at a much higher bit rate than specified
for it during encoding. For example, files encoded to play at 37kbit rarely
get below 70kbit when observing the bit rate in the QT player, and files
encoded at about 768kbit stream at a whopping 1.3Mbit on average.
What gives? is the QT player simply not reporting accurate numbers (the
same problem occurs when streaming the same movies off a real server).
Do I need to "choke" the movie bit rate by using ref movie or is the QT
player simply wrong when it reports these massive data rates?
Also - why do the streamed movies look noticeably worse than the same file
played off your local hard drive, while consuming more bandwidth than
specified at the same time?
Most of the movies are Sorensen3 2-pass encided with Purevoice audio -
could this be a matter of codec choice?
Thanks for any pointers or explanations for what may be going on here.
