Identifying Blank Frames / scene change in a video clip
Can anyone help me how write c++ code to identify a blank frame or scene change in a video clip. Am totally new to this issue, if my query is inappropriate please suggest me where can i put-up my post. Please suggest websites or links where I can find c++ code samples related to video processing & handling.

Do you have any code already that loads and/or plays the videoclip ?

blank frames can be identified because each pixel in the image will be identical (within a certain threshold).
scene changes are harder to solve. if you mean hard cutouts (screen fades to black within a few frames) that's fairly easy to detect.
An actual camera change is hard to detect, it could be a change, it could be a fast flow of imagery causing rapid change in the image (fast camera movement, explosions, ...)

scene change detection gives a lot of hits in google...
