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.

@softworkz

Thank you.

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