Migration Issue? 4k not working well on DS920+

Try 4K with a TrueHD track and let us know how that works (transcoding audio and video)

I’ve now played a few 4k (HEVC Main 10 HDR) files, around 55GB with TRUEHD 7.1 and CPU usage is usually around 12-16%, it peaked at 24% or so for a few seconds.
I’m pretty impressed so far!

Thats impressive. Are you sure the truehd track was transcoded and not direct played?

I believe so…

Thats really impressive. Looks like Im getting one of these! Thanks!

I can confirm also, worse behavior in converting what was marked as H264 to H.264. I’d get a blurry screen that wouldn’t update, but audio kept streaming. May be an artifact of my (older) process to rip. I can go back and re-rip, but the XML change worked perfectly for me. I edited the file directly with BBEdit on a Mac and confirmed that it kept the Linux/Unix line endings (as it should). My guess is that it really doesn’t need to transcode, but does because the H264 vs. the H.264, which may be a bad rip.

SD (H.264) (hw)

SD (H264)—Transcode (hw)

Thanks for this thread!!! This prevented me from dropping the install and going back to a separate machine!

For those reporting blurry transcodes here,

When you add the VaapiDriver="i965" preference in Preferences.xml, does the image clear for you as it has for others who’ve reported the problem with the J4xxx CPUs?

Chuck – I can confirm, this fixes problems and the image looks good to me. Low CPU utilization when HW enabled.

To all reading here.

I just confirmed with the transcoder team —

They’re waiting for the correction to this problem, which Intel has identified and verified to work, to be released.

As soon as it hits “public”, they’ll be able to pull the updated drivers and update the transcoder.

IT IS IMPORTANT

to revert this manual preference setting after the transcoder team is able to get things working and released to us.

The iHD driver is better than the i965. The i965 is susceptible to speed issues with very high bit rates (nearing 100 Mbps). 100+ Mbps is common in movies with a lot of CGI.

@ChuckPa Hi mate, with regards to my topic you just closed, the issue i was outlining was with your i965 preferences.xml workaround from this thread already in place (and i know it is working because hardware transcoding is completely unusable when not), so unless you are suggesting that the upcoming iHD driver fix from Intel will also fix the 720p quality issue beyond the current workaround, i believe my topic is still a valid separate one?

@Arsenal

Please jump back to the thread.

Any chance you can do us a huge solid and let us know here when it’s fixed Plex side? Thanks for all your help through this!

I most certainly will poke my big rock-hard head back in here when it gets resolved. :slight_smile:

Thanks @ChuckPa. This work for me! :heart_eyes:

As intel has released the Q3 2020 release, when can we expect either a driver compile we can manually put in the file system (synology), or an updated release with the new driver?

As of today I have migrated from a DS216 II+ to a DS920+, I do not have (yet) 4k content.

Should I still do the VaapiDriver=“i965” modification ? Or is it irrelevant for non 4k content ?

Apply it now. 1080p or 2160p does not matter.

Hi @ChuckPa I take it there still no word from Intel on them releasing the updated iHD driver?

I have this and several other threads bookmarked to make announcement in when we do get the update.

Please understand: Unless you’re trying to play 100+ Mbps videos,

the i965 interface is more than adequate for all but the most CGI intensive 2160p HEVC movies (e.g. tons of CGI characters and fully computer-generated scenes)

the i965 interface can handle all H264
