Artifacting when using hardware acceleration transcoding with integrated intel graphics

@T_Le what gen of intel quicksync are you using? Some older chips still look pretty bad, not because of plex, though. I forget exactly when they started looking better, but I believe it’s around 7th-8th gen+. This a screen shot of 720p 3mbps on rick and morty for me on a 8th gen intel @dan-the-man

@Dentifrag Wow I’m quite jealous of the quality that you are pumping out. I’m using the latest i3-10100.

Snap, same CPU and I get this issue heavily on lower quality videos. I thought I was going mad until I saw this thread. Hopefully the fix doesn’t take too long.

@Claret you have the new alpha build for windows, correct?

@Dentifrag Not yet, I will try it over the next couple of days and hopefully that will be the end of it. Only just found this thread.

@claret you kind of joined in at a good time. Issue was finally fixed (it seems for a good amount of people so far, there are some still having some issues) 2 days ago. If you go up a could of replies there’s a link to the download for the fixed alpha version. Or if you’re not into alpha stuff then wait a bit for an official release

@Dentifrag Yep, so i gave the alpha build a whirl yesterday and yes seems to be much better on playback, didn’t appear to degrade in quality. Great.

However, I have now had 2 failed recordings on the DVR with transcoder errors this morning which can’t be just a coincidence. Hmmm, so gonna reboot the server, and a flick through the logs, to see if it goes away otherwise I am probably gonna have to revert back to the official build and wait it out. Frustrating.

I have an i5-8250u cpu in my Yoga 730. I’ve got the Plex Media Server 1.20.2.3249-085351107 (Windows x86) mentioned in this thread installed. Can someone outline everything I need to do in Plex Media Server (I have Plex Pass) to enable hardware accelerated transcoding using the intel gpu on this laptop? It uses Intel HD Graphics 620. I would really appreciate it.

Go into settings, transcoder, and check the boxes

Done. I don’t know how often I’ll even use transcoding, as all of the files are 720p or 480p .mp4s using 2 channel stereo 128 aac audio. Every now and then an ios device will require transcoding because the Plex client on that device is not set up properly.

@Ridley Do you have an idea when this will make it into the beta build?

Cheers!

@Ridley or anyone that knows the answer - when will this make it into the beta build? Thanks

Finally it is here: Plex Media Server

Yeah I just spotted that as well!

I just switched to the Beta channel and checked for this update. Successful update, and early tests still look consistent with the Alpha build that had been previously posted.

Just loaded the latest beta and the Windows Intel transcoding is a lot better. Been poor for while now. The improvement is substantial and greatly appreciated.

Out of curiosity, what’s CPU usage supposed to look like when hw transcoding? I see some GPU usage but CPU still spikes to 100% occasionally. Using ASRock J4105.

Depends on the audio track and/or subtitles. An HD lossless to lossy conversion with pgs subtitles would easily peg the CPU.

Mine feels heavier on the cpu then it used to. I notice the fan spinning up quite a bit when a hardware transcode is being performed. I’m sure there was less cpu activity before the update.

I’ve noticed high CPU as well. The “Plex Transcoder.exe” process seems to use around 15-20% CPU per transcode on my i3-8109U NUC, apart from the GPU usage. The transcodes used are standard 8Mbps x246 1080p encode transcoded to 3Mbps 720p with srt subtitles.
Is this the new normal?
