Video plays in browser but not on TV

[rumbles]

Hi all.

I have a video that plays fine in browser but only plays for 5 seconds before crashing on TV. I'm not sure what's wrong and would appreciate someone with more knowledge giving me a hand please.

Jellyfin is in a docker container and the TV points at the server ip and the exposed port. Other videos run fine on both browser and TV.

The TV log is here: https://pastebin.com/JzYDUZL0

And the browser log is here: https://pastebin.com/MMy6Z2SS

Any help or pointers much appreciated

Because it is Dolby Vision 7.6 video. I'm ASSUMING the browser is falling back to DV 8 or HDR10. But I question whether that is the correct log for the browser playback. I am not aware of browsers supporting fallback.

You didn't mention what KIND of TV OS, but I'm going to assume Android TV. If so, it is a known issue that exoplayer, the playback engine built into Android, does not properly fall back to HDR10.
