Streaming problems. In each set, the top pic is from my program's "viewer", which is directly from the camera, uncompressed. The lower pic is from the QTPlayer window.

This is all being done on MacOSX 10.4 "Tiger". 1.5 GB RAM Dual G5 1.8Ghz, etc. etc.

When the numbers are red - I'm also recording to disk. That makes my framerate go down as QT sucks the bandwidth. Even though I apparently get each frame as they're recorded properly - and this streaming stuff occurs after I modify the frame with the readout.

==================================================================================
This picture shows what the initial image looks like. Only the very top draws itself.

==================================================================================
I can "clear the screen" by waving my hand around to get as many changes as possible. This seems to work mostly as expected:

Picture 1
==================================================================================
Now we have a relatively decent stream....

Picture 2
==================================================================================

But as time goes on, the image starts to weird out, and do the Salvadore Dali melting watch thing: Ignore the readout in this case, this starts happening with a second or two (taking screen shot caused my program to crash)


Picture 4
==================================================================================
And more....


Picture 5
==================================================================================
And more....


Picture 6
==================================================================================
Until it's just a purple amorphous blob....

Picture 7
==================================================================================


If I create movement, the blob will move around - in correct time - but it's still a blob. It tracks my beard quite well - but leaves it totally wacked. If I create a great deal of movement, I get the whole frame correctly again.

==================================================================================

This is presented in the hopes that somebody out there more knowledgeable about this will say something like, "Obviously, as any moron can see, you forgot to do 'x' " -- or whatever.

Thanks!
