One of my users showed me that their PS5 Plex app skips ahead a few seconds randomly during playback of an x265 movie. Played file locally at the exact timestamp where it happens to them - fine. Played file on remote PlexWeb as well - fine. Confirmed with them that their PS5 app is the latest version available from the Playstation store. There are multiple posts on this problem, and they’re all closed so I can’t add on / reply to them. Some are from over a year ago. And no helpful replies from Plex staff on any of them.

Has the Plex team acknoweldged this issue and is there a timeline for a fix?

Same here.
Really annoying issue.
Any update of the PS5 app incoming ?

Please fix this. It’s happening to me too on my ps5

It’s because PS5 doesn’t support x265. In the app go to settings>video and untick ‘direct stream’ - it’ll play transcoded but keep the quality and it doesn’t skip

I’ve managed to narrow this issue down to having SRT subtitles (not burned-in) enabled. I’ve played multiple 4K HDR HEVC files and don’t experience skipping issues unless I enable subtitles (not burned-in).

Other than this issue, the PS5 Plex app is fairly solid.

The PS5 does support HEVC or else it wouldn’t play in the first place.

It does reduce quality, especially if you’re not using the experimental HEVC encoder with appropriate hardware.

Googling PS5 x265 the first page of results all say it’s not supported without conversion. there is some contention on the top result reddit post.

I have seen a couple reddit pages saying it can direct play 265 but none of my 265 mkv’s can. they do direct stream to the PS5 app but 4K ones skip, as per the OP. Tautulli says it’s converting the container from mkv to mp4. Are your 4Ks mkv or mp4?

I have a gigabit cabled connection PS5 end and the Plex front end which is an M1 Mac mini so it’s not a bandwidth issue.

Unticking direct stream fixes it and the transcode quality is just as good for me, maybe you need to tweak your transcoder quality. The M1 doesn’t support hardware transcoding so that experimental encoder is set to never.

After some more experimenting, the skipping issue is completely gone for me if I disable the subtitle option “Auto sync subtitles”.

I take that back - not the case. Only turning off subtitles completely solves this issue reliably.
