I'm digging a bit the codes involved with the camera module. I'd like to get a monochrome video stream and made some trial by modifying raspivid. It is possible to get the raw YUV, even RGB. But for optimization, I wondering if it is possible get directly only one byte per pixel with camera parameters such as :
Is some one knows which 'fourCC' codes are actually supported ?
I have some difficulties as well to find where are implemented the "effects" on the videos, such as 'oilpaint' 'negative' or 'gpen', is it accessible ?
Thanks a lot !
