Even though I have marked this as a Bug, I'm not sure if there is much I can do because of the SurfaceView and TextureView surface functionality and how the ExoPlayer (and other VideoPlayers) interact with them. I'll see if there are any optimizations I can do to minimize the duration of the blank screen (this should just be the color of the activity or other views behind the EMVideoView bleeding through)

Perhaps this is of interest google/ExoPlayer#852

Hmm, interesting... For reference, the link ojw28 points to is now invalid (because of repo changes); the full versioned link is https://github.com/google/ExoPlayer/blob/6a5cd6889258df6b9a08b770e2bf351a5bb30e18/demo/src/main/java/com/google/android/exoplayer/demo/PlayerActivity.java#L193

I'm having a difficult time reproducing the issue in the current master branch on KitKat through Nougat. Are there other devices that you have noticed this with?

[rohan31710]

I got the same issue. But why my last rendered frame is not visible after resuming the activity. You can observe this issue in all devices above 4.3. Even with demo app you will see the same issue.

Nope, I have 8 different devices I have tried this with that don't have the issue as I mentioned above. What I do see is the TextureView or SurfaceView being blank for a moment however no audio is played until I see video frames. If you can reproduce it I would appreciate if you would look in to the issue and find the culprit

If you are wondering why the last frame isn't still visible it is because of how the SurfaceView and TextureView handle data.
