Can you share a preroll video with me?
I don’t use any.
If I can replicate, I’ll gladly write it up

Don’t believe an actual content link is required here. Pair two video files of different encoding types and resolutions and I’ll be it goes boom.
All my files are huge. I don’t have small files … but OK… I’ll try it.
what does this mean?
Received.

I’m impatient 
Showed me the auto countdown – then
I can’t recreate with that simple a test.
Which toe do I need stand on again? 
I did mention two different encoding types being required. Try this with a x264 pre-roll and a x265 main video file.
That (admittedly extra) snipe at the end reflected the pain of getting multi-channel audio x265 videos to play at all after one update (not sure if that was Plex or Google though) until optical passthrough is enabled. When I got this new Chromecast back in Nov '20 Plex worked perfectly on this device. Have had to revert back to my Roku where I don’t want to sit through a reboot several times an evening.
Please help me out?
Make it simple for me?
How about a Step-by-Step ? (something even a support guy can follow? 
)
- Setup a Plex Pre-roll
- Play new X265 Encoded video with different resolution than pre-roll
- Pre-roll displays normally and the main video starts playing but zoomed into 1/4 of the video.
- Stop video
- Resume video
- Wait for reboot.
Using the pre-roll provided by @JuiceWSA ,
I tried this all kinds of different ways:
-
Start, pause, FF, play the last 15 seconds of preroll, transition itself into 4K. FF the 4K, stop the 4K. start the 4K. wait for boom… NADA!!!
-
Same as above except letting it all run itself through, then into the movie, back to the pre-roll, skip all around… NADA!
Just how easy is this supposed to be to recreate?
I can follow these steps and recreate the issue on two different chomecasts and many others are reporting this issue (look for all the reports of “zoom” issues and crashes as I’ve replied to several).
This also appears intermittently with x265 Series but usually only in the course of auto-advance. Maybe we’re all just making it up?
Ah,
New piece of info… the player.
What happens if you use Plex Web like I am?
Details , STEPS TO RECREATE, are important 
I’m not saying you’re imagining it. I’m trying to learn how to recreate it
Think I just lost track of which sub-thread I was in here as the topic is a client-centric one. This same content does play fine via casting via Plex Web. I moved away from this approach to the Roku “it actually has a remote control” model and was happy to move back to the Google TV experience of the new Chromecast.
I also can’t play HEVC files (takes forever to start and then starts buffering every few seconds). I guess the issue started today.
I’m using a Linux server (Plex Docker image).
Clients that work: Plex for Windows, Plex for Android TV.
Clients that don’t work; Plex webapp, Plex for WebOS.
Tried downgrading but that doesn’t seem to help.
I’m working over here at the moment, trying to focus in on the problem.
At present, I’m trying to decide if it’s “stuffed” , “STUFFED”, or “TOTALLY STUFFED”.

Hmm, do you perhaps have subtitles enabled for these HEVC files? What is PMS installed on (the server itself i.e. is it a Synology NAS, or is it Linux, or is it Windows, etc)?
I ask because I have a similar sounding issue with all versions of PMS. I think it’d help to find out if your issue was related to mine/MagaZine’s (linked by ChuckPa above). If it doesn’t appear to relate, I will back out. But getting more info can determine which direction to go in.
EDIT: Just noticed you SAID Linux. I guess my mind is scattered all over and I just lumped that into my own issue, since Synology DSM is a form of linux.
DSM is based on Debian Linux.
Synology has added their own GUI, tools, and some custom hardware to the motherboard.
We usually keep it in its own category along with the other NAS devices because:
- Headless
- Usually have a very underpowered CPU compared to a typical desktop/server class.
FOUND the sidecar (external) subtitles problem
Being fixed right now.
(this fixes the hard playback failures)

Update:
- What was found was a problem with the XML.
- That problem is minor by comparison.
My concern (the core issue here):
-
Attempting HEVC HDR tone mapping (which is enabled by default) on a machine which isn’t capable
-
Subtitle burning on top of that load.
I would like to be as definitive & exacting as I can so this can be identified

Here are the logs from the latest build of Plex (1.23.3.4707-ebb5fe9f3) on Linux Mint 20 (Ulyana) build.
As before, HVEC files are failing to play.
Plex build 1.22.3.4523-d0ce30438 is working fine and that is the last build where HVEC files did play.
- HEVC is working for everyone else. We’ll find out what’s not working for you.
- Please TURN OFF the VERBOSE logging. I cant see anything with all that noise. DEBUG only is the default.
- What is the Nvidia driver version? Drivers WERE updated.
