Hi everyone

I'm working on a remote controled robot which have four cams & one sound recorder.

the robot encode the data send it to a computer,
an Application decode data and view 4 cams & play sound.

Here are my questions
1. Must I write a new codec(encoder/decoder) to view live cams & play sound because it's live & not playing from a file?
2. If I must write a codec then how can I show data? Is there some functions that can help?
3. Else what?

I need your help,
tnx so much
