Hardware transcoding fails on HEVC main 10 10bit profile

Hi

 

I just observed since upgrading to 4.3.0.30 that hardware transcoding fails and falls back to software transcoding on hevc main 10 10 bit profile.  I not totally sure, but I think this was working before.

 

Server info:

Emby server 4.3.0.30 running on ubuntu server 18.04.3 LTS, kernel 4.15.0-72-generic

Intel NUC8i5BEH1 with Core i5-8259U processor (Intel Iris Plus Graphics 655), 8GB RAM

 

Attached, hardware detection logs and ffmpeg logs.

 

Is that normal to fallback to software encoding with this media?

 

thank you

@@rouq - You need to disable the hevc vaapi decoder, then should be able to get hw accelerated encoding.

Thank you.

 

Just for information, is this temporary? The issue comes from the igpu, Linux drivers or ffmpeg?
