Video player has been interrupted

[Abhishek-doceree]

My Flutter TV app downloaded multiple videos from server to Samsung Tizen TV and try to play sequentially. Videos get freeze and app got crashed with following error:
Video player has been interrupted

[E] external_texture_surface_egl.cc: PopulateTexture(126) > eglCreateImageKHR failed with an error 12291 for texture ID: 13
[E] [ERROR:flutter/shell/platform/embedder/embedder_external_texture_gl.cc(122)] Could not create external texture->

@Abhishek-doceree Could you please share your sample code? we will try to reproduce this issue.

 }

On Samsung Tizen TV calling VideoController method like dispose(), seekTo(), pause() or even checking status like controller.value.position, controller.value.isCompleted, controller.value.isPlaying throw error.

[+14786 ms] [I] Dart async error: PlatformException(player_get_play_position failed, Function not implemented, null, null)

PlatformException(player_pause failed, Invalid state, null, null)
PlatformException(Player error, Error: File format not supported, null, null)
PlatformException(player_set_play_position failed, Seek operation failure, null, null)
external_texture_surface_egl.cc: PopulateTexture(126) > eglCreateImageKHR failed with an error 12291 for texture ID: 3

Got above exceptions.

After calling await vc.dispose(); app get crashed.

@Abhishek-doceree We recommend using the avpay plugin on TV device, as it offers better performance.

It is important to note that when creating a new player, the previous player must be released.
