HEVC video Stutter

[Jacob2me]

Server Version#:1.18.9.2578-513b381af
Player Version#:6.10

When playing certain HEVC streams with AAC 5.1, the video is very stuttery and jerky. If I enable experimental player, this does not happen. Also, if I transcode to x264, it also works fine. What could be the issue? I have tried playing the video on VLC, and it works without issue. Also, according to playback info, the video is playing at twice the bit rate it actually is, and therefore it appears the player is double playing every frame?

Issue essentially fixed on newest version of plex that enables enhanced video player for all users.

Stutter still happend on iPad and AppleTv4k with Plexplayer. iOS player works fine. The files are encoded with Nvidia hardware nvencc64, quality VBR. Infuse works fine. Please fix.

Hint: I enable under Help „show information“ and there I can see that dropped frames is increasing (5-10 pictures every second)

The files you’re dealing with are - BROKEN.

If waiting for Plex to maybe come up with a solution isn’t something you want to do - you can fix them:

Example of stuttering HEVC playback on Apple TV 4K

I think I might have found the source of the issue with these files. I noticed when RARBG first started releasing these files, MKVToolNix (v44) would produce a messed up file after re-muxing, and as mentioned in this thread, version 45 no longer causes an issue, and in fact resolves it for many players. So I reviewed what they changed in MKVToolNix v45, and saw two noteworthy entries: mkvmerge: H.265/HEVC packetizer: fixed changing the NALU size length, it was using the wrong offset into the…

The bad news:
They require fixing at this time.

That doesn’t look like one of the files I’m talking about, but…
If you run those ‘original troublemakers described in that thread’ through V45 of MKVToolNix - it fixes 'em.

Looks like the issue you have isn’t with the file.

I’ve got 477 to go…
