Hello plexers
I have a buffering bug that needs some attention. Present in the Xbox One Preview release but also in the regular release. I have a 1h 4K HDR 50mbps video file that buffers like crazy. Is unplayable unfortunately. Setup is Xbox One S connected via Ethernet (cat 6E all gigabit hardware) Plex server is Ryzen 7 64GB ram, 1080TI, powerful enough. Weird thing is I only have this issue with the Xbox, I tried setting the connection to force insecure but still get major buffering playing back large 4K files. I also have a roku tv connected via wireless AC wifi, strange thing is the same 4K file and all my other 4K content play flawlessly with the plex app on roku. So I’m not sure what’s going on here. My Xbox being a way more powerful machine and hardwired should be showing the roku who’s boss but the results are completely backwards.
On my plex dashboard when I’m streaming to my roku over wifi I’m maintaining a 50mbps, direct play. No transcoding and checking task manager shows little cpu usage and around 50mbps of network transfer as plex reports.
When streaming to the Xbox the plex dashboard reports 100mb, direct play stream and checking task manager shows again little cpu usage but does show between a steady 150mbps which is significantly higher then wifi yet the stream still buffers.
All that leads me to believe the issue is indeed the Xbox app, ether the buffering cache is way too low or the app is just straight up mis managing the stream entirely.
Ether way I would love a developer to look into this. I’m stoked the Xbox app is finally getting a much needed update but this bug has been present for a long time now. So long I actually felt the need to reach out and ask for a resolution. Anymore technical feedback you require please ask an I’ll report back. I’m pretty sure this should be easy enough for anyone to replicate.
Thanks plex team. Excited to hopefully see a resolution to this.
I had the same issue. This is a known bug I think has been addressed in the latest Early Access version as far as I can tell after some testing. However, it has other issues while it’s in this early access form like frame rate which make it VERY difficult to watch 4k content regardless of your hardware or speed etc. I tested this theory out by running it on a different device (Samsung TV) through the same variables and it works fine there. This is an Xbox problem.
