[REQUIRED] Use case description

In my app, when developing disconnected from the cameras vpn, I find it handy to steal some frames from public rtsp streams, and this one is my favourite one:

rtsp://31.0.225.93/cam/realmonitor?channel=3&subtype=00&authbasic=YWRtaW46MTIzOTg3

but EXOPlayer doesn't show frames from this public camera because of the following error:

Server did not provide timing for track ...

Proposed solution

I understand that the protocol from that camera may be not fully compliant to rtsp standards, but I found that commenting lines 516-519 in RtspMediaPeriod.java make the camera perfectly visible.

Alternatives considered

Add an EXOPlayer settings option to make the control optional
