I read documents and suspected that its read only. I tried with that also it still does not work. (crwxrwxrwx 1 504 504 81, 0 Mar 12 2004 /dev/video0) is available in /dev. I have less experience with Linux but I have used color conversions using v4l in past. I was successful with framebuffer part. /dev/fb0 opens just ok and all ioctls are working fine for framebuffer on the same board.

This has linux from mistral on this. There is a node /dev/video0 on this but when I try to open this using O_RDONLY or O_RDWR option, this does not open device. Is V4L functionality missing in this case? >We are using Linux version 2.6.22.1.
