Linux RAW Video (YUV/RGB) Reading & Transformation

Hi,

Please Help !!

I am a very new person in the world of Audio & Video Enoding / Decoding.

The current assignment that I have been given is to develop an engine (in C) that would transform various RAW RGB & RAW YUV files from one form to other, i.e. RGB to YUV & vice-versa. ( RGB888 & below and YUV444 & below)

Being a very new professional in the field of Digital Media, I am really stuck up with certain documents that I managed from the net. I read information as to how to use mathematical formulas to transform these files.

The biggest problem Im facing right now is How to identify the format of these YUV & RGB files.What is the format of the Structure that defines these RGB/YUV Files.

I hope you would be kind enough to spare some of your time to help me start up with some proper solution to this problem right from the grass root level.

Just give me some idea about the Structure that I can use to Decode these files in my programs, coz once I know the Structure, its just the matter of Parsing which is a relatively very easy task.

It wold be great if you can show me a code segment ( preferably in "C" ) that reads & writes RGB & YUV files

Desperately looking forward to a quick reply from you....

Thanks & Regards

A Matiman

Here is a more precise information about the type of work I want to perform, Take the YUV/RGB file (no information of any sort available inside the file) input with the details mentioned seperately on the basis of the various options available and transform it into any of the desired YUV/RGB format with the maximum possible portability options as possible (444, 422, 421, 420, YUYV or YUY2, YUV12 ...)

This really isn't a Linux question. You want to go to some kind of site that defines specifications and standards like the IEEE web site.
