Hi! I want to convert 8 bit grayscale byte array image (1024x1280px) streaming at 200FPS in realtime. I've tried with python, but its too slow (19FPS) on CPU, and I am unable to make PIL work on GPU. Any ideas? I actually want to use OpenCV for this, as it would also help me perform other operations on the data simultaneously. But my real problem right now is to convert 1024x1280px raw image to jpeg at 200FPS in real time. Any help is appreciated.

Thanks in advance!

You can find info about GPU JPEG compression and decompression library for high speed cameras here: http://www.fastcompression.com/products/jpeg/cuda-jpeg-library.htm One can get throughput even more than 1000 fps at megapixel resolution for 8-bit raw images.
