Matlab code for MPEG/h.264 video encoding and decoding

Started by chaitanya June 28, 2007
I am in need of a MPEG/H.264 codec in matlab. I want to play with the
compressed bitstream i.e. headers , motion vectors ,VLCs etc.
I need to convert a video into mpeg bitstream .... and then put my
watermark in this compressed domain.
It would be great if anyone could provide a solution(preferably in
matlab) for the above ....
Thanks and regards
