video processing in C++ / C

[PESITdude]

hi,

I basically wanted to know how to write codecs in C/C++ for the .mp4 format. Is it even possible...? Also where can i find what's there in the mp4 file. I mean i need the data-structure of the .mp4 file. (Similar to the C structures of .BMP file format - http://www.fortunecity.com/skyscraper/windows/364/bmpffrmt.html).

Is it possible to write a .mp4 file reader in C/C++. I mean it should read some basic info like the bit-rate, dimensions of video, the compression used, fps etc...

thanks in advance.

Of course it is possible, but keep in mind that mp4 is MUCH more complicated than BMP. You have been warned.
