Emby choppy playback on Apple TV - started only recently

[invader 17]

I’ve been watching movies and a TV show with the same format for a while. It’s recently started playing choppy. Looks like it’s playing with frames skipping.

I saw in the Wiki (https://emby.media/support/articles/Apple-TV.html) it says:
“If using h.265 make sure your videos are tagged as hcv1 and not as hev1.”

I did this and it does fix it. I’m just wondering if there’s anything that can be done to not have to do this to all my files, they were working before.

Also, if I change from MPV to NATIVE player, that also fixes the issue. There are other issues with the native player that make me want to use MPV if possible.

 

Apple TV settings:

Format: 4K SDR

HDMI Output: YCbCr

Chroma: 4:4:4

Match Content: Range & Frame Rate

 

Emby App settings:

Preferred Video Player: Auto

Apple TV app Version: 2.0.1 (7)

Emby server version: 4.9.1.80

 

Happy to provide serverlog, sample file and video recording of what the choppiness looks like if that’s helpful.

Thanks in advance.

Correction: tagging as hcv1 didn't fix it. What fixed it was turning off subtitles. They are the same text based .srt subtitles that used to work OK.

Thanks Luke. I just messaged you the log and examples.

Hi there. I just tried again and it seems to be with subtitles off too. Is there anything else I can provide to help?

 

Thanks.
