Server Version#: 1.19.5.3021 Player Version#: Plex Web 4.37.1 I recently acquired a Quadro P400 and turned on hardware transcoding with NVENC. This works, and playing HEVC files in Plex Web (Firefox or Chromium) sucessfully transcodes them to h264 using the GPU: https://fb.hash.works/ldQuTY/ Howe…

[image] hashworks: Also we have today’s 450.57 in the Arch staging repository, I’ll try it out later. Bug is gone with today’s linux 5.7.8 and 450.57 from the Arch testing repo, works just fine! I’ll mark this as a solution then. @ChuckPa can you add nvidia 440 as buggy to the wiki page ?

Interesting. I can confirm it transcodes fine with it forced on. in those settings. Is it possible to adjust timeouts so that quality can still be adjusted from maximum at all or is that not a solution?

I think the first part of this is to confirm everyone, with all the various processors, can get playback to work in Plex/web that way. Once we’ve confirmed it works that way, we can then gather the Plex/ web logs and figure out if it’s a regression(or just broken) or it needs to get smarter for…

I can confirm the same behavior on my server using nvidia. My server that uses quicksync is unaffected and starts playback much faster.

@taylrjones Which behavior are you confirming? :slight_smile: The failure or the success ?

Both, transcode works fine if I specify the quality level before starting playback. The transcode fails if I try to change quality on the fly. And this issue only occurs with my nvidia card, quicksync works as expected.

Any updates on this? The bug is causing a poor experience when playing via plex web.

@stevezau I only have access to a GTX 1050 ti card. It is installed in the lab’s QNAP TS-877. I do not have any difficulty / ‘poor experience’ when lowering resolution. ‘Poor experience’ is subjective. A discrete repeatable failure is something we can look at and figure out. Can you give me…

Hi @ChuckPa , Happy to troubleshoot and dive into the issue with you. Whatever you need. Here is a recording of the issue https://drive.google.com/file/d/1Xy-85T6VdEPs657_O3YXuLJHYPGk8r1a/view?usp=sharing When I change I also noticed several 404s in the console log [image] Steps to reproduce P…

Please tell me: Quality settings you selected. System you’re using to run PMS (include the CPU make & model). If possible, please verify DEBUG logging is on and recreate this. I’ll send you a PM so you can forward the logs ZIP file to me. I’m asking this because I’m using my LG C1, as shown be…

Also seeing this problem as per my post here [BUG] Plex Web Playing failing when changing Transcode to specific rate. However works if set to "automatic" - #9 by stevezau. Just FYI.
