Casting to chromecast (gen3) not working

Whenever i try to cast a show to my tv with my chromecast gen3 it just skips through all the episodes and wont play

Some shows work and some don’t

What is the client app, please tag this topic correctly with it.

I discovered the same issue on a 3rd gen Chromecast and Chromecast Ultra 4k.

My TV does not support Dolby Vision HDR HEVC content, and this turned out to be the issue. Then Plex Server doesn’t have a license to decode Dolby Vision content, so it can’t transcode.

Each episode tries to play, silently fails (I don’t know how to get long messages from a Chromecast) and tries to play the next episode and fails sequentially until it reaches the end of the season).

So it’s usually some format incompatibility.

In this thread where it mentions the same issue. It seems that there are logs that you can get from the app in About.
