I am writing a Windows NT application using VC++ 6.0.
I am receiving digital video data in through a HOTLink interface card.
I am required to save this digital video frame information to file.( that's the easy part)
Later, I am required to display this video frame data. (frame by frame) or "real-time" from file.
I understand the digital video frame data format. And can extract window size, and each pixel word data.
It seems that this will be a cumbersome task to do display all this information back to the user frame by frame, painting pixel by pixel.
Not knowing to much about displaying video or video in general my questions are:
1) What is the file format of uncompressed video?
2) Is there a tool to display, what I am assuming is called uncompressed video?
3) Should I try to compress the video data?
4) Will compressing the video data change the file format to JPEC or MPEG or whatever it is that will make it easier to replay this digital video?
Thanks for any help you can give.
