Apple TV Enhanced Video Player- still has slowdowns and stuttering

Server Version#:1.20.4.3517
Player Version#:7.9

I am still having trouble with stuttering video on Apple TV. Stutters on new Plex video player but not on old player. There have been countless threads here about this issue. Plex devs keep saying that its been fixed when it still has not for many people.

I am still having trouble with stuttering video on Apple TV. Stutters on new Plex video player but not on old player. It only really happens with HEVC content.

same here.

Plex devs refuse to even acknowledge this issue exists

Sometimes media, especially HEVC media, isn’t stored or muxed perfectly.

Try this on the ATV:
Turn off Direct Play
Turn off Auto Adjust Quality (if it exists)
Leave Direct Stream enabled (if that exists)

There’s very little harm in turning off Direct Play for most (non Dolby Vision) media. It allows the server to remux the file on-the-fly, which can make it more palatable to the player.

A similar test is to remux a problem file with MKVToolNix:

And one last is to remux it into an MP4 - it’s easy with ffmpeg, but there are other tools depending on your OS:

ffmpeg -i inputFile.mkv -c:v copy -c:a copy -movflags faststart outputFile.mp4

None of those will change the quality or recompress the video, but if the playback problem is related to muxing issues or timecode issues within the stream, it might help.

I don’t think this is a plex problem so much as an apple TV issue. I’ve had the apple TV stuttering even with Netflix and Prime. Anything above 576p on my UnRaid server was unwatchable. Switching to a plex app installed on a new LG TV and bypassing the appleTV has completely solved the issue. Netflix and prime play perfectly. I can now play up to 4K files off my server with ease, and no more stuttering. My AppleTV is frankly junk now…

I’ve never had issues with anything but Plex

I’ve turned off everything but still get the stuttering. But it appears that with subtitles off it doesn’t sitter anymore.

Edit: nope. Still there. This is ridiculous.

I have been having similar issues but only with some video files. I noticed that the files that have issues will also take a long time for the stream to start as well. All of my files have been encoded with web optimization but now looking at the file info I see that my older encoded files show that they are not web optimized (curious as I went back years ago made sure all my files were encoded this way) while my recently (last few years) encoded files show that they are web optimized. All of my files are in m4v (Apple) format.
Doing some play back trials I noticed that the files that are not web optimized per Plex start playback almost instantly while the newer files that show as web optimized take a while to start and then stutter during playback.
Turning off direct play back or the enhanced player and using the native player resolves the issues. Unfortunately I cannot use the live tv feature then because my server chokes on the OTA format transcode.
All of these files playback fine on two Roku sticks that I have.

This (turning off Direct Play and Auto Adjust Quality) resolved my stuttering / delay issues with TV episodes recorded by PLEX DVR. Thanks for the suggestion.

I’ve turned off both of these and neither affect my playback issue
