Full HD video processing possible?

in Integration and Hardware • 10 months ago

Hi, for a new project I need to process a Full HD video signal coming from a webcam and output it to a Full HD beamer ... now I have doubts about the performance ... basically I need to put different filters on the image, one will be a pixelating filter and another a monochrome filter. Is this possible with processing / is there enough performance with a mac mini 2.6Ghz i7, 4GB RAM?

Thanks for any help!!

Full HD output is most likely not a problem. The filters you describe can be done with one or more GLSL shaders to get a good performance. The only problem may be the full HD input. You'd have to test if this works for example with Processing 1.5.1 and GSVideo. All in all this seems pretty feasable, but I don't know the mac mini specifically.

Hi thanks for your answer. Why to test with Processing 1.5.1 when there's already version 2? Can't I use GSVideo with version 2?

Processing 2.0 is currently still in beta. So you have indeed two options:

Use Processing 1.5.1 (the current stable build) with GLGraphics and GSVideo
Use Processing 2.0 (the latest beta)

Andres Colubri who wrote the GLGraphics and GSVideo libraries has been working on Processing to include their capabilities to Processing 2.0. So importing those libraries isn't needed (or possible) anymore. The argument for option one would be stability, available documentation and forum resources on these versions. The argument for option two would be all-in-one solution and future-proof for upcoming (?) final release of Processing 2.0. The arguments against option two would be currently still perhaps unstable beta, recent api changes and at the moment still lack of documentation.
