video bitstream

How can i read an mpeg file from my code for further processing? Actually i need mpeg bitstream in binary format.

...mpeg file
elementary/multiplexed/MPEG 1 or 2/with audio?
...from my code
Which language?
...for further processing
What kind of 'processing'? Change resolution/color correction/reencoding?
...mpeg bitstream in binary format
every mpeg bitstream is a 'binary' format!?

Actually i want to divide mpeg bit stream into 48 bytes packets each and assign priorities for transmission. programming language is java. can work in C too if any library available.

This sounds like sort of 'file transmission'... But you can do this with any kind of file, even without knowledge about the 'content'. I can't see your point...
Th usual 'transmission' format for mpeg bit streams is the transport stream format. But this uses 188 byte 'packages'.

Can u specify more clearly what exactly i need to do. I want small packets of mpeg stream and assign priorities to them.. am a beginer and don't have much knowledge of mpeg and all..

Actually I don't understand what you really WANT to do...

ok..In ATM networks there is a threshold limit of buffer size which contains the arriving cells. that
threshhold specifies how many more low and high priority packets can be accommodated in buffer. currently this threshold is fixed. our guide has designed a variable threshold protocol. for its testing some sort of data packets(53 bytes for ATM 48 + 5 header) with random high-low priority is required. therefore we have decided to use video data to test it. and since its my major project i wanted to divide mpeg into packets myself and assign priority level . i hope it is clear now. please do tell feasible solutions.
