I have an analog camara(CVBS) connected to a video decoder, and its digital video output (ITU-R BT601) to the AVR32 ISI.
I have an user program reading frames from capture interface an writing them to framebuffer:
- read a frame (720*576, YUV packets)
- color conversion (YUV422 to RGB)
- writte frame to framebuffer (/dev/fb0)
Using this, I have 10 fps ... which is not enought form me :cry: .
I am thinking two posible solutions.
Sol 1: Use PICO (pipeline operations): I think the color conversion should be faster. Anybody know if any driver is already done for this? (Cause I don't want to reinvent the wheel)
Sol 2: Use /dev/video1 interface.
What do you think would be the better solution?
Thanks in advance,
