BUG REPORT - PMP Windows Jerky Playback

Plex Players Desktop Players
1

Plex Media Player for windows is still completely unusable for watching any videos, live tv or recorded TV.
Playback is extremely jerky and freezes every second for maybe 1/2 a second.
Every other media player (I have lots) on the same computer playing the same media plays it flawlessly so there is clearly no issue with the hardware or the media.

PMP for Android has no issues playing these media so its only a problem with the windows player.

please fix this

thanks,

  1. Try enabling ‘native open gl’ in settings
  2. Also might play with hardware decoding

Item 1 fixed my issues

I’m seeing the same thing, and noticed this in my logs:

Looks like it’s doing little skips ahead and back.

In the meantime, Plex is completely slamming the network, using a sustained 168Mbps to direct-play a 1.4Mbps file.

I’m wondering if you see the same excessive bandwidth and log messages?

I’m getting the same issue:

I didn’t check network usage at the time.

I checked the Use native opengl
Enablwd hardwarw decoding
Sync mode = audio

And that seemed to help
