HEVC playback Issue on OG Chromecast

[alanpaone]

Describe the bug

one of my users has an OG chromecast (the 1080p key-shaped one, its otherwise surprisingly fine), and can't play HEVC movies. I found the workaround to turn off tonemapping (would be interested to learn why that works, also), which allows us to sort of play these files, but playback buffers a lot. These files used to not play, and this is somehow more frustrating. Looking at the FFMPG logs, the resolution is weird, I'm seeing "Height":1606,"Width":3840", the chromecast tops out at 1080p, and is plugged into a 1080p TV. The FPS is probably because I'm using the quicksync on a celeron, and is survivable, but the resolution.....doesn't seem right.

To Reproduce -Press the Cast Button within Android App -select OG chromecast -attempt to watch an HEVC/H265 movie -Errors and Buffering

Expected behavior This show plays well on my Chromecast Ultra, which supports HEVC.

Logs Here's the logs from 3 of our attempts to stream the show. There's nothing in the Jellyfin logs around this time, so I didn't both attaching them.
