Plex Windows App Stuttering on playing some mkv video

I’ll ‘de-transcode’ my S3, and test.
On my desktop (5820K/16Gb) there wasn’t ever an issue that I noticed…

Was having this same issue as recently as last night on dedicated laptop running Windows 10 Pro/ 2.5 GHz Core i5/ 8 GB RAM / 64-bit.

Still stuttering for me on the Surface Book (i5 6300u), over a fast 5GHz WiFi connection, and a fast Braswell-based 3.4 GHz CPU on the server.

Version 2.1.3.1 is making its way to the store. I’d appreciate feedback regarding whether the workaround helped at all. From what I’ve seen, I was able to get perfect playback on a powerful desktop machine, but no change on a slowed Surface Pro 3. Looking forward to hear about your experience.

I have 2.1.4.5 installed on my Surface Pro 3 running Win 10 b14316, and stuttering is very bad. If I play the very same MKV file using the Movies & TV app, no stuttering what-so-ever. If I change the playback from Original to say 1080p 8Mbps or 720p 3Mbps, stuttering goes away but then the content is being transposed on my server. Also, I just tried, successfully without any stutter, with the Web UI in Microsoft Edge on the same system.

If it matters, I have 0.9.16.4 Server installed on a Windows Server 2012 (which happens to be an HP Microserver).

@ChrisLynch06 what happens if you disable Direct Play in settings and leave Direct Stream turned on? This should cause the video and audio streams to be remuxed (but not transcoded).

I noticed this as well. I just abandoned using the plex app(s) all together and watch full screen in Chrome.
Although there are certain TV’s I have no choice but to you the smart-TV app, which has the same stuttering issue.

Did not fix anything. Still stutters. If I play the very same video on my Xbox One, it plays perfectly fine.

@ChrisLynch06 are you able to provide me a sample file I can use to test?

Any chance they release the fix before next non insider build (redstone) ?
I am using a lot plex sync on my laptop to have some movies for kids on the go and currently it is not usable because of this stuttering… Is syncing with encoding in 720p prevent the problem ?

It doesn’t seem the fix will be backported to TH2, so redstone will be the first version to contain the bug fix.

So wait and see…

I confirm that I have still the stuttering problem with 1080p videos. Using latest Plex app on a laptop (core 2 duo / 4go ram / GeForce 8600M GT / Windows 10 v1511 x64). Let’s hope the fix in redstone release will work…

@o_spring do you have any Virtual Machine you could use with Windows 10 build 14328? I believe it should be fixed in that build.

I still have app issues on windows 10. Chrome browser is the way I watch now. Only problem is the app on the smart tv doesn’t work either. same issue, buffering.

I have a machine running the latest insider preview build. I should be able to test it this weekend. Fingers crossed.

Awesome, fingers crossed here as well!

Late with my reply but didn’t get a chance until last night to test. i don’t see the stuttering that i was getting. However, i am still getting the same old message about having trouble keeping up. This is on both the local machine running server and on a remote machine that is gig-Ethernet connected. Both machines are modern powerful machines. The strange thing is that I don’t see cpu or memory peg when this happens. Once i start trans-coding, I see the frequency reduce until I get to 720P 4Meg and the problem goes away.

The logic behind that warning is roughly that if we accumulate more than 2 seconds in the Buffering state, we pop up that message once. Aren’t you seeing any buffering?

Oh it’s buffering. But i don’t know why. i7 Broadwell with 24 gig of ram is running both Plex server and the Plex app. Windows 10, Plex server, and Plex app are all running off of the same m.2 pcie ssd. Same issue with i3 Hazwell with 8 gig connected over gigabit Ethernet to the server (previously mentioned i7/24 gig). On both machines, I have to go to 720P 4M to guarantee that all media will play without buffering

One would think that the transcoding would eat up more resources than direct play. This is not an issue running Plex Media Player or Plex Home Theater. it is as if the Plex app itself is resource restricted. Maybe sandboxed with limited RAM?

@Just Mark: Can you try playing the same file with the Movies & TV app and see how it behaves there (it’s a valuable comparison since we rely on the same OS player component)?

i need help please
i have a media server i5 cpu 8GB ram running windows ,i only play locally through my Samsung smart tv that is connected via Ethernet cable .All works fine playing 1080p movies but some movies doesn’t want to play it only buffers ?Very strange considering half work and half doesn’t!Some advise or help will be great full!!
