Raw video frame access in Linux

Hi everyone,

 

I want to know if from Linux we can have access to the raw video frame to do some calculation before in goes in the Encoder module.

Here's a short description of my system :

I have a camera(NTSC) connected to the video input of a DM365. I want to encode in MPEG2 the video feed and store it on a compact flash. Before the encoding of a frame, I want to be able to compute the sum of all pixel in the frame.

I want to know if from Linux I will have access to that information.

Thanks and regards,

Jerome Baron
