Question about Video Encoding
I'm not sure if this is too general a question to ask on this board, so please let me know if this is not appropriate.
I'm wondering if there are any sites online that will give me the detailed specification for the exact structure popular video formats (like mpeg, realplayer, wmv, etc), with information such as this, which is for bmp:
That is, which bits encode what, and what I need to know in order to decode frames of the video.
I'm thinking about writing a program that can convert some popular formats into "keyframe only" format, and I feel like if I can decode the meaning in the video files, I might have a chance at doing that.
