tvOS leaving app and reentering cause video to freeze. #23

Open zmartell opened 2 months ago

zmartell commented 2 months ago

Hi,

I noticed that in simulator its ok, but not on a real tvOS device, if you have a video playing, press "back" or "home" and then go back into the app, the video freezes but the audio continues.

It seems to break vulkan when its no longer focus. Is there a way to reinitialise?

You can test it out with demo.

  1. Play one of the sample videos
  2. press back/home.
  3. open app again
  4. see video frozen but audio continues.

Some logs I captured:

"press BACK/home".. and then...

This is a known issue and currently there is no good workaround.
