My Intel i3-8100 with UHD630 is able to transcode 4x (from HDD) and even 5x (from NVMe) concurrent 4K streams:
1080p would be much more. I do not have enough Clients / CPU Power to test this scenario as well, but should be ~20x as shown through others multiple times.
You wondered about high IOwait compared to Nvidia. I think this isn’t really an IOwait as there is no IOwait on the disks. This is only related to the fully utilized iGPU which is not able to answer fast enough. I think this simply means its overloaded and you reached the maximum video processing limit. You can check this by installing Intel’s GPU Tools. I posted some screenshots in the Unraid forums.
For anyone familiar with the details: when considering 8th-gen QuickSync processors, is there a substantial difference in overhead for transcoding h.264 vs. h.265 (source files are all 1080p)? Much of my library is 10-bit h.265.
first I wouldlike to thank you for this info. 2nd Is using the QS in windows still not working right? I would really prefer windows cause I am very bad with Linux. 2A. If Linux is the only way I have setup a little linux box using ubuntu 20.04 with PMS installed. I have a windows 10 pc setup with storage spaces setup that holds all my media. I am having a really hard time with getting plex on the linux box to find the network drive. I have it mounted via smb ( I think) but you are saying to mount each folder from the windows nas to created folders. I cant seem to understand how to do this. D you know of a youtube video or a walk through for noobies? most of the ones I have found seem to think I know linux and I very much dont.
On windows its super easy and I feel lie mounting a drive and having plex access it shouldnt be this hard. any info you can give me would be great.
