CSI

On rock pro/lite, there is CSI camera interfaces, the rock pro/lite default kernel supports OV5640 and OV2659 sensors. Most sensors of this two model on the market are compatible with rock pro/lite on hardware. Note, the kernel should be newer than July, 25th. Check this commit.

Kernel driver supports resolution 800*600, NV16, YUV422P and YUYV formats.

Read image with ffmpeg from command line .

 ffmpeg -f video4linux2 -s 800*600 -r 20 -i /dev/video0 test.mp4


Program with V4L2 library examples.
