Hi, everybody.
I'm have to set up some sort of virtual (net) TV and I have an audio
problem.
When I create some live channels (RTMP streams) with Red5, after a while
the sound quality degrades considerably. Hissing and noise, and.. so on. It
may impove for while and degrade again later.
I'l paste bellow the code of a Red5 Application which shows what I'm doing.
