Which part shall I modify if I want to display 2 stream simultaneously?

[MegaThomas]

I'm trying to play 2 streams side-by-side. I've tried to add more videoRenderer (like 2 videoRenderers, 1 audioRenderers & textRenderer) in the DemoPlayer, but I found ExoPlayerImpl has selectedTrackIndices which limit the number of active video tracks.

I suppose I can't use 2 players since I want to efficiently sync them. Which part of the video rendering pipeline should I change besides ExoPlayerImpl?

in release-v1,

player.setSelectedTrack(TYPE_VIDEO, 0);
player.setSelectedTrack(TYPE_VIDEO1, 1);

work?

For V2, this is answered in #2855.
