[Live-devel] again need help of special video and audio data

[maherry]

Hi,again.
In the early letters we wrote like following:

I think out a method to solve the problem,but I don't know whether it is right.So ask you some advice.
In the FAQ I see the typical control flow is 
'source1' -> 'source2' (a filter) -> 'source3' (a filter) -> 'sink'
so if I can program a filter to abstract the standard video data and standard audio data than the server receive the standard data from the filer. Will this be OK? Thank you very much!
If it will works, could you please give some example of the filer?
