Fast Video for OPENGL HD 1920x1080 (Read 712 times)

ascorbin Junior Member Offline Posts: 63	Fast Video for OPENGL HD 1920x1080 Jan 11^th, 2008, 12:06am Well, actually I'm working on a project which should play HD Video 1920x1080 px in the background and a OPENGL 3D UI above. I was trying the faster movie class, in P2D its ok, but in OPENGL its very slow. Has anyone a clue? greetings ascorbin

If you must be in OpenGL but your video is faster in P2D can you try to:

1. createGraphics to make a new buffer in P2D (not sure if it's supported.. what about P3D?)
2. create the rest of your app with opengl
3. use image() to draw the buffer in your opengl app.

I'd be interested in your results. Never had to do HD 1080p in Processing before... D:

Something like a System.arraycopy() or just arraycopy() You should implement a framerate counter of some sort and do some testing to figure out where your bottleneck is.
