Describe the issue you are experiencing

Hello, I started using ADB integration with my Android TVs and I'm having an issue. The object entity_picture is empty - a black image is displayed as the background of the media player, although all other functionality is working properly. Two MI TVs.

Describe the behavior you expected

The TV screenshot was expected to be displayed, but this problem persists for any application enabled.

Steps to reproduce the issue

Reboot everything, rechange everything, change TV

If you just try to navigate to that URL, does it show an image?

E.g. for other entities with entity_picture, if I just append that path in my web browser, it shows the image.

So if that was my install, I would test the url:

http://homeassistant.local:8123/api/media_player_proxy/media_player.mini_tarata_adb?token=24bd076c1e1dfce4a4f036006eaf02ff15814dcef84e06d892aebe0e577c027f&cache=3c952aee3d482675

If you can't pull up the image just with your normal web browser, than I will say this is not a frontend issue, but something in the integration is not correctly hosting the image, in which case you would need to file a core bug.

Empty file... So, this is a bug? Does this function work for others?

[karwosts]

I would add this information to a core issue for the adb integration. I don't think there's anything further that can be done here in frontend.

[ar30v8]

I'm new, how to do this?
