Hi.
I’m using Exoplayer in my streaming app for Android TV, I have Nvidia Shield Pro 2019 as testing device, Android TV v.9 installed.
After upgrading Exoplayer library to the latest version 2.13.0 I’ve noticed that HLS streams are not playing smoothly while same streams with same settings on the same device played smoothly with 2.12.3 and before.
I’ve tried different streams from different sources, they all behave in a similar way.
Try this stream for example - there is a marquee below, in 2.12.3 and before it was flawlessly smooth, in 2.13.0 it stutters every second or about that.
SurfaceView is used to show video, TV screen refresh is adjusted to video frame rate.
Studied Release Notes, documentation and sample app, cannot find what’s wrong, can you please help?
Player initialization code is below:
public static SimpleExoPlayer initPlayer(Context context, SimpleExoPlayer player, final String videoUrl,
View videoView, final Player.EventListener listener,
final boolean tunneled, final boolean silent, final boolean forceMaxBit) {
if (null != player) {
player.release();
