[Q] Directly generating RAW movies


Hello :

I have a simple problem with my Video Rate Microscopy Software. I stream live video to disk at 30 frames per second in a "very raw" format: 500 x 500 pixels of RGBA values, straight from the acquisition board. Because of other constraints (I analyze the data in real-time), I really need this streaming to be fast (well, who doesn't?). The problem is that I need an extra step after the acquisition to convert my Raw format to the Quicktime movie format. I know the difference between my file format and the real Quicktime RAW format is very small (as I have hexdump'ed , my RAW and the Quicktime RAW conversion and compared them). Ideally, I would write the Quicktime header myself when I create the stream file and add any other little atom that is needed to save *directly* to Quicktime RAW that can be edited and incorporated in any document easily without the extremely annoying extra step of having to go through my little conversion app that makes the raw file into an actual Quicktime movie. That would save me the trouble of making a simplistic "Video Converter" that I really don't care about. Is this something possible or am I just looking for trouble? I have found the quicktime API daunting.


Daniel
