[streaming] Re: About streaming and transcoding

[Jose Luis Garduno]

Hi,
I have the same question here, i am trying to make some kind of rate
adaptation.
The idea is to set up a VOD and to read statistics from rtcp and then
to trigger this output-changing-thing, so far im still figuring out
how to do it... if someone could enlighten us :)
