4K HDR playback issues on Chromecast for Google TV

Something strange is happening on my new chromecast/server and I’m not sure what.

Last week my housemate bought one of the new chromecasts and installed Plex, I asked him to try the Mulan I’d recently downloaded in 4K HDR and it direct played locally perfectly.

I have since bought a chromecast for google tv and tried playing Mulan on mine but it doesn’t work, I have the loading circle as though it is constantly trying to buffer, it also never shows up in my now playing on my dashboard. I thought maybe there is an issue with the server so I go ask him again and it works fine for him.

It also works on a LG 4K HDR TV played remotely but failed on another TV with Chromecast for Google TV remotely.

These are identical chromecast for for google tv, connected over the same wifi network to the same server yet one will work and the other will not. I have no idea what is going on here.

PMS is on latest update and as far as I can tell the chromecasts are running the same builds.

The only thing I can think of is that my TV is not HDR while his is, would this throw a spanner in the works regarding this? If so can some settings be altered to alleviate this or is it a case of you can’t watch any HDR on a non HDR TV?

The logs for yesterday (19/10/2020) should show an attempt at playing it remotely in the afternoon, followed by several attempts at local play in the evening. There is a resume play and a play from beginning on the device it worked on, the rest of the attempts locally are failed plays by myself.

Many thanks, for your assistance.

Did you figure out what the problem was? I’m having the same issues.

Unfortunately not, I’ve chalked it up to my 4K TV not being HDR but I don’t know for sure.

It might be your google TV display settings. I found mine default to 1080p which made plex try and transcode. Setting to 4k it does direct play instead.
It should be noted that even with direct play I’m having a some buffering issues. At this point I’m thinking its compatibility of the file with Google Tv’s Plex. I had more luck with the chromecast ultra so I might try casting to it instead see if that gets a better result.

In your case it sounds like the file compatibility isn’t an issue so hopefully the display settign does the trick for you.

Did you find the problem

Almost same issue. Have an HDR TV. I can cast to the new chromecast from ios app and it plays fine. But playing through the plex app on android tv stutters. It also gives the video needs to be converted due to HDR message when playing starts.

Seems like a restart sorted it. I can now play 4k HVEC 10bit HDR with EAC3 through the google tv app without issues.

I’m having the exact same issues. Pinning it on the theory that HDR content doesn’t work well on Chromecast with google tv, because it works just fine on my Apple TV 4K. Can someone confirm?
