OK, I know that pd/pidip is cool for linux 2-D stuff. What about winXP? I was trying to map video onto cubes in gem, but I could not avoid the frame refresh popping.
You mean tearing - like no vbl sync? VBL sync is a feature missing from the Win32 and Linux versions of GEM, but present (and the default setting) in the OSX version (it's literally one line of code in OSX). I think it could be added to both platforms, although I don't personally know how to do it.
a 720x480 avi is no texture I think, even with my 512MB ATI 9800 and AMD 2600 w/ 1GB ram.
You have a 512MB 9800!?! I didn't even know those existed - I'm envious. Anyway, that setup should do at least one stream of 720x480 no problem. Have you tried setting the 'frame' message to the refresh rate of your montior and then using a counter object to drive pix_film playback (in other words don't use 'auto').
The GL methods for texturing in Windows and Linux aren't quite as optimized as OSX primarily because Apple had to implement them to add the hardware acceleration to the Quartz GUI. A necessity for Apple became a boon for video and 3D apps on the platform.
Whats the tool for windows? (as my linux laptop is pokey with its usb-audio card that doesnt really work well... >100ms latency)
Well, consider replacing that laptop with a Mac laptop if you are desirous of doing real-time video. All of the current models will do at least one DV size stream even the iBooks. The Powerbooks will do two or more depending on the hard disk used. Both Jamie and I develop GEM on Tibooks, so the code is well tested on them.
