V4L on OMAP3

Could you please tell me what exactly you are trying to do?

I am able to open the device /dev/video0 here at my end. Please verify your configuration file for all the required options. Here are my /dev/video nodes on my system -

[root@OMAP3EVM /]# ls -l /dev/video*

crw-rw----    1 root     root      81,   0 Jan  1 00:00 /dev/video0
crw-rw----    1 root     root      81,   1 Jan  1 00:00 /dev/video1
crw-rw----    1 root     root      81,   2 Jan  1 00:00 /dev/video2

Hi,

I am not able to open device node, fd_v4l = open(v4l_device, O_RDWR)
returns -1. 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.
