Ah, I guess you misunderstood me, Plex’s hard decode acceleration works fine for me (Fedora and ArchLinux), but it uses the VA-API interface for codec support, which by default costs more performance than the QSV interface - which can be interpreted as Performance is worse than QSV interface.
The illustration may be a strong evidence that Plex is using vaapi as a codec interface on my Fedora
I’ve searched the community, but they don’t have much discussion on QSV decoding - they only care about hardware decoding working properly.
Like: Ubuntu Intel N5105 QSV HW Transcoder not detected
According to the log, Plex didn’t try the QSV decoder in the workflow, it only tried the VA-API decoder - which is in line with the priority order mentioned in the Plex documentation. That’s why I thought this was a feature request at first.
