Having the exact same issue in 4.7.11. Ubuntu 22.04, 13700k Happens in both native install and in a docker (with /dev/dri passed as a device). Emby user is in video and render groups. Everything works fine for both Plex and Jellyfin. Emby used to work, not sure when it stopped.

Hi all, I have run into a rather weird issue this evening after reviewing my hardware encoder options. After seeing a remote user connecting and playing a media file that needed to be transcoded due to global bit rate limitations, I noticed that it was streaming at a rather low bitrate of ~900kbps when the global limit was set to 2.5mbps. My upload speed is more than capable of achieving this and has done so without issue in the past. I hopped onto DSM to see what was up and found my CPU usage was spiking to 99-100%, which was causing the slow down. This has never happened before and I would typically only see CPU usage of 10-20% while transcoding any file, so I thought to check my hardware acceleration options, as per the wiki suggests, to ensure nothing was switched off. I found that I still had hardware acceleration set to 'Advanced', but weirdly enough, no options appeared under 'Preferred Hardware Encoders' as they had just a week ago. See the screenshot. It is almost as though it no longer recognizes any of the hardware options for hardware acceleration on my NAS. I am stumped as to what has caused this sudden switch. My only inclination would be that it has to do with my recent upgrade from Synology DSM firmware 6.2.3-25426 Update 3 to version 6.2.4-25554 last evening. That upgrade went smoothly and nothing indicated there was an error, but this is the only major change from last week to today. I have confirmed that this occurs both for remote users and myself while local. This issue occurs on a variety of different platforms including Amazon Fire TV devices, Firefox, etc. I also confirm that the spikes completely subside once I stop playing/transcoding of media files. Direct play files are seemingly not causing spikes of this nature. My Emby Premiere license also appears to be correctly input and resolving fine. I am also running the official package, not within Docker. Any help would be appreciated so I can adjust my hardware acceleration options to not cause spikes. Included is the server, hardware, and transcoding log of a problem file. Thank you. Server Specifications: Synology 920+ 8GB Memory Firmware: 6.2.4-25554 Emby: 4.5.4.0
