I'm trying to split a 1920x1080 video into 4 separate 960x540 streams for processing and then re-assemble back into a 1920x1080 stream.

Hello,
Can someone can help me?

I've attached a basic example.
Thank You!

Hello Marker, I would like to keep things in Open GL only as in example patch.

To do the job, i usually use "@rect" attribute from "jit.gl.pix" ...

Hey Matmat, Thank you very much for the reply, I appreciate it, but I'm trying to keep the crop dimensions to 1/4 of the input resolution. So a 1920x1080 input with 4 crops @ 960x540. This would allows further processing of each cropped signal at the reduced dimensions therefore lees strain in the GPU. My example and your example still process each crop at input resolution.

But you could setup the "jit.gl.pix" with the good resolution ?

Hey MATMAT, that did the trick.
muchos gracias!
