Hello All,
I have a doubt about H263
How can I find out the macroblock boundaries with in a GoB of H263
bitstream??
Does a Block / Block data with in a macroblock have a fixed size??
So that I can calculate size of the first macro block and advance to the
next one and so on..
could any one help me on this....
Thank you in advance

Lau,
You cannot jump to the beginning of the next MB
without parsing the current MB data.
GOB markers if present are the only points that you
can sync to.
