Player crashes with InvalidResponseCodeException sometimes

[PiN73]

I tried to play example video. It works well, but about in 5% cases it prints the following exception

E/ExoPlayerImplInternal(25866): Source error.
E/ExoPlayerImplInternal(25866): com.google.android.exoplayer2.upstream.HttpDataSource$InvalidResponseCodeException: Response code: 403

and the video is loading infinitely showing on-screen error

Full output when video is crashed

Output when video works

Tried on different networks, different emulators and physical devices, debug and release versions.

Just made number of tests (launch app, press play, wait until playing started or error occurred, close app, repeat). Used the following parameters

FluTube(
  'https://www.youtube.com/watch?v=nPt8bK2gbaU',
  aspectRatio: 16 / 9,
  autoInitialize: true,
)

the result is ++++++++-+-++---++-++++++-++++-+ (+ means worked, - means error)

I'm aware of this. But unfortunately i think there is not too much i can do since this error occurs in the video_player plugin :( I hope they will fix it one day... I know it is not a flutube error because i did some debug and all URLs are loading well before creating the player, but it sometimes just crashes because, i believe, there is a race condition somewhere in the video_player plugin code. Sorry not to be more helpful. If you know what the error is and where it happens, you could open an issue in the video_player plugin repo.

So it is not related to copyrighted videos and encryption? From readme:

PLEASE NOTE: Embedding copyrighted videos is actually not possible.

[ja2375]

Nope. This error happens with all videos. If you try to embed a copyrighted video, it won't play at anytime. No matter if you retry.

OK, thank you for explanation

You are welcome :)
