Proposed solution

Adding SRT support and low latency presentation mode (#1179) would make ExoPlayer suitable for near-realtime video streaming.

Alternatives considered

https://github.com/ThibaultBee/SrtPlayer is an implementation that reads data via SRT and presents it to ExoPlayer, but it's not production ready.
