From: rgb123 on 22 May 2010 10:14 Hi Could anyone please guide me as how to find the RGB values of a video(.avi) file. I am a starter and I would like to know some basics to start with. Thanks

Thanks You are more likely to get a useful answer in a video-related forum.

Thanks Likely, nowhere. It depends on the codecs, but I believe most codecs will tend to use YUV-ish color models instead of RGB. RGB is also a bit of misnomer, since it's not "a" color model, but a set of them (sRGB versus Adobe RGB, e.g.). Googling online, it seems that the DivX codec for AVI uses YUV. -- Beware of bugs in the above code; I have only proved it correct, not tried it. -- Donald E. Knuth

AVI files are containers which can hold any of at least dozens of different encodings of data in practice. So the first thing you would need to do is determine which encodings are being used, and then read up on those. Though in practice there is open-source code already available to do such conversions for you, such as ffmpeg. - Tim |
