Issue description

After upgrading from ExoPlayer 2.4.4 to 2.5.1 we are having an issue with Nexus 7 devices not switching properly from one SimpleExoPlayerView to another one. What we get is basically a gray screen with a couple old frames on top of the screen partly visible.

Reproduction steps

This behavior occurs if the user rotates the screen during the first few seconds from starting the playback during which the application recreates the player fragment that contains the SimpleExoPlayerView and sets the player for the new SimpleExoPlayerView instance.

This issue is 100% reproducible on our app after upgrading to version 2.5.1 of ExoPlayer and causes the playback to lock up and the artifacts from the video surface remain even in the device homescreen if the user is able to navigate away from the app when this happens.

Link to test content

Test content shouldn't matter but I can provide a link to one of our live HLS streams through email.

Version of ExoPlayer being used

2.5.0, 2.5.1, also tested using dev-v2 branch

Device(s) and version(s) of Android being used

Nexus 7 (2nd gen), Android 6.0.1

A full bug report captured from the device

Will include this in the email as well.

I doubt this worked particularly well prior to 2.5.1 either (there would have likely been a noticeable delay before video started again after the rotation)?

If at all possible, you'll likely find the experience is much better if you can handle the orientation change yourself and avoid recreating the activity. How feasible that is depends on how complex your UI is, and how much of it you need to swap out as a result of the orientation change.

The reason the behavior is different now is likely a result of DummySurface (actually intended to make this type of case more seamless, but apparently not working quite right on all devices). We'll try and reproduce, and revert back to the old behaviour just for this device if that's the best course of action.

Yeah it's true that on previous versions the change wasn't as seamless as it is in the newer versions and the user experience is much better on most devices that we have tested but unfortunately it seems to introduce a new issue at least on this device.

I think we should re-evaluate if we can have a common layout for landscape and portrait orientation in the future to make it more compatible with all devices but at the moment due to the app design the portrait and landscape layouts of the player activity differ quite a lot so it isn't really that simple to handle the change manually.

Reproduced. It's really quite bad :(. Will blacklist use of DummySurface for this device. Thanks for reporting!

It's actually not DummySurface causing the issue, since the same problem happens switching directly between two real Surface instances. We probably need to disable use of MediaCodec.setOutputSurface on this device.

Should be fixed in dev-v2. Please verify!

Works great in dev-v2 now. Thanks for the quick fix.

their SimpleExoPlayerView no longer works properly. There
are also valid use cases for having multiple metadata/text
outputs.

* Restore the interrupted flag after blocking operations

If the main thread was interrupted during
ExoPlayerImplInternal.blockingSendMessage/release, the interrupted flag was
immediately set but then wait() was called on the next iteration. wait() would
immediately throw InterruptedException, causing the main thread to spin until
the blocking operation completed.

Instead of resetting the flag immediately, reset it after the blocking
operation completes.

COLOR_FormatYUV420Flexible.

* Allow more aggressive switching for HLS with independent segments

We currently switch without downloading overlapping segments, but
we do not actually switch more aggressively. This change fixes
this. Note there's an implicit assumption made that if one media
playlist declares independent segments, the others will too. This
is almost certainly true in practice, and if it's not the penalty
isn't too bad (the player may try and switch to a higher quality
variant one segment's worth of buffer too soon).

* Fix attr inheritance in SimpleExoPlayerView

When creating PlaybackControlView inside SimpleExoPlayerView,
we want certain attributes to be passed through. This lets you
set control attributes on the SimpleExoPlayerView directly. We
don't want all attributes to be propagated though; only our own
custom ones.

Not sure if there's a cleaner way to do this. Pragmatically this
solution seems ... ok :)?
