Exoplayer and Rtp Multicast support #4294

Hi,
I'm trying to integrate Rtp support from this pullrequest(#3244) into newest ExoPlayer version. I created necessary files and copy paste code in existing ones.
Everytihing seems to work good, project compile without any errors but when I'm trying to play video nothing happen.

Debug log code:
I/ExoPlayerImpl: Init 8e1481f [ExoPlayerLib/2.8.1] [p212, MAG410, Amlogic, 23]
D/EventLogger: state [0.03, 0.00, window=0, true, BUFFERING]
I/Choreographer: Skipped 42 frames! The application may be doing too much work on its main thread.

D/EventLogger: loading [0.21, 0.00, window=0, period=0, true]

I'm testing this on ExoPlayer demo app.
Could you please give me any advice on what I'm doing wrong? Thanks.
