@ojw28 @andrewlewis We have faced the same issue. We have a player application which needs to loop a slideshow of videos. The views are dynamically constructed based on the dimension config and then attached. The first video may need to play in a full screen and the second one might play in 500 * 500 square.
For every file playback, a new SimpleExoPlayerView and new Player instances are created. The previous player instance is stopped and released.

The last frame of the first video appears as a static image in the second player view and the second video continues playing only the audio.

Everything absolutely works using android videoview and media player. We are planning to migrate to ExoPlayer and stuck with this issue. Can you please help us out?

Issue description

While playing multiple videos in SimpleExoplayerView using different dimension configs, the last frame of the first video is overlapping on the second video, But Still, we are able to hear the audio of the second video.

Reproduction steps

1.Play a video in SimpleExoplayerView [Width: 100% and Height: 100 %] and after the video is completed release the player and change the visibility view to GONE.

2.play another video in a new SimpleExolayerView with different dimensions may be [Width: 50% and Height: 100%] then you will see the last frame of the first video being overlapped on the second video
But still, you can able to hear the audio of the second video

My Demo Application source code is available in this link https://github.com/vishnuganta22/exoPlayerDemo

If you try installing my demo application on your device then you need to place any two videos named 1.mp4 and 2.mp4 in Downloads Folder. I have also screen recorded my device. You can watch this video for a better understanding of the behavior https://vimeo.com/229082192

@ojw28 Can you please reopen the issue?

[andrewlewis]

The description is quite hard to follow and we don't really have time to debug your application's code for managing views/players. It sounds like something is getting reused in the second playback (a view or player).

Please could you provide a minimal patch to the ExoPlayer demo app that reproduces the issue?

[vishnuganta22]

@andrewlewis Thanks for reopening the issue. I will try to send a patch on your demo app

Here is the clear problem description,

The application needs to play a slideshow of items. The item types are video and a custom designed view template which can have a slideshow within.
This is how it's implemented -
The layout has a dedicated main SimpleExoPlayerView which can play videos.
The template is constructed dynamically(new relative layout with a SimpleExoPlayer and some other views) and attached to the main layout on demand.

The visibility of the main SimpleExoPlayerView is reset as below before attaching the template view.

public static void resetSimpleExoPlayerView(@NonNull SimpleExoPlayerView videoView) { ExoPlayer player = videoView.getPlayer(); if (player != null) { player.stop(); player.release(); videoView.setPlayer(null); } videoView.setBackground(null); videoView.setVisibility(View.GONE); }

Whenever the template view is active (attached and visible) the new exoplayer view instead of playing the respective slideshow video, it just shows up the previos main video last frame and only play the audio.

Please watch this recorded video https://vimeo.com/229082192

@andrewlewis @vishnuganta22 Adding this line to resetSimplExoPlayerView() method have solved the issue.

videoView.getVideoSurfaceView().setVisibility(GONE)

But at the start of playback the video region flickers in black colour on every transition which is a little noise for the user.

[andrewlewis]

Are you saying that simpleExoPlayerView.setVisibility(View.GONE); doesn't hide the first player, but simpleExoPlayerView.getVideoSurfaceView().setVisibility(View.GONE) does hide it?

For the flickering issue, I wonder whether this is due to the shutter background color (see #3172).

[vishnuganta22]

@andrewlewis setting simpleExoPlayerView.getVideoSurfaceView().setVisibility(View.GONE) fixed our issue

[rohit5ram]

@andrewlewis may be setVisibility() of SimpleExoPlayerView should be overridden such that simpleExoPlayerView.setVisibility(View.GONE); will setVisibility to the whole viewgroup

[andrewlewis]

simpleExoPlayerView is a parent of the SurfaceView, so the SurfaceView should be hidden when you hide its parent player view (hiding a view group hides its children). This is the behavior I see in the demo app if I hide the player view, but it's not consistent with the behavior you've described.

If you snapshot the view hierarchy after hiding the player view do you see its child SurfaceView still set to be visible?
