Direct Play jolting/stuttering

Plex Players Desktop Players

Server Version#: 1.14.1.5488-cc260c476
Player Version#: 2.26.0.947-1e21fa2b

When I play content to any of my compatible devices it Direct Plays however the video jolts/stutters so I thought it was because I didn’t have a Plex pass but that made no difference after purchasing.

  • Tried an ethernet cable connected to the router directly and the device, made no difference.
  • Tried Wi-Fi and it made no difference.
  • Thought it was my mechanical HDD so I moved everything over to an SSD, but it made no difference.
  • Thought it was my firewall is so I allowed the relevant ports, it made no difference.
  • Thought it was maybe because ports not forwarded so I forwarded the relevant ports, made no difference.
  • Thought it was because I encoded the videos to x265 so I encoded to x264 however it made no difference.
  • Disable Debug Level because I thought that might be causing issues, made no difference.
  • Changed video quality of Home Streaming to difference options and it made no difference.
  • Changed Scheduled Tasks to run at times no one will be using the server, but that made no difference.

Played the videos via VLC using Plex DLNA feature and no jolting/stuttering.
Played the videos in Emby over Direct Play and no jolting/stuttering.

I’m at a loss and have no idea what to try next any suggestions welcome.

I had almost similar issues. Running Win10. Tried almost every forum with no solution. They said it’s some recent Win 10 update which is the issue, I don’t know if its the case or not. I’ve given up trying to resolve it.

Here’s my thread of that issue

yeah not sure to be honest with it only being the media player might be the application itself.

hey just wanted you to know that I’ve resolved this issue finally via third party program, TCP Optimizer. I simply set my internet speed and then selected the ‘Optimal’ settings in the bottom. It changed the registry settings for those files (I’ll advise to make a backup through the ‘File’ menu).
Then reboot the system once and the Plex starting streaming without any buffering again.

Last windows update definitely messed up some of those registry settings which this tool apparently fixed.

In the past, it was exactly this tool which caused trouble with Plex, so I’m not sure what to make of this.

what was the solution in the past? has there been a solution?

anyone? note again only happens with the windows Plex Media Player doesn’t happen in the web browser when transcoding at maximum.

I can provide logs if someone is willing to help.

Have you tried the following:

Put PMP into its ‘TV mode’
click on the user avatar, then Settings - Main
Try toggling

  • Hardware decoding
  • OpenGL

You can later switch back to ‘Desktop mode’ if you prefer it.

Hi @OttoKerner thanks for passing by!

  • Just TV mode, stutters around every 30 seconds
  • TV mode and only Hardware decoding set, stutters around every 30 seconds
  • TV mode and only Native OpenGL set, no stuttering
  • TV mode with Hardware decoding and Native OpenGL set, no stuttering

I did change back to ‘Desktop mode’ and no issues… What does this mean?

@Rikuddo this might help you out as well?

It means that your graphics adapter is better compatible with PMP’s native OpenGL mode. Keep it activated, along with hardware decoding (to keep cpu load lower).
Some settings you make in TV mode are also effective in desktop mode.

Thanks for the response. Does having Hardware decoding set make the video have less quality?

So the TV Mode and settings I changed is for the laptop I’m streaming to. I thought Plex relied on the Plex Media Server (PC) having the good hardware or is it that both the server and media player require good hardware?

Not in this case.

These are different things. The server is using the hardware to transform the media format if necessary.

The player is using the hardware to decode and display the video.
