Probably unrelated but looks like Silvermont isn't exactly as Ivy Bridge and does have B-pyramid capability.

Do you know which driver you're using, and are you sure it's up-to-date? Since your driver doesn't have OpenCL support, the log doesn't tell us that.

Yes, I have the latest graphics driver installed (version 10.18.10.3408 - https://downloadcenter.intel.com/Detail ... ldID=23636).

it might take some time to investigate but will look into it

After launching the thread over here and after ordering the given PC, I can now confirm that the J1800 is not offering the normal QSV performance :) . I would not say it is as bad as the experience from overwale, but QSV is definitely slower than normal encoding. Still, ARK confirms that this particular CPU indeed offers QSV.

If you need any specific results or if I can assist in any way, just give me a shout.

Seems like HandBrake or any other tool for QSV is not at fault, it's just Intel holding back on the drivers. It took me quite some effort but hidden in the corners of the internet is this little page: http://www.touslesdrivers.com/index.php ... code=40504. For those that don't speak French, it lists a newer driver for Bay Trail graphics (made in January, released in February) that is currently unavailable from the Intel website. Sure enough, installing these drivers suddenly unlocks QSV to its full potential. Converting Wreck-It Ralph in medium at 1080p was going at a nice 4fps, but enable QSV and it jumps up to an impressive 70fps.

So, in summary: go grab the drivers from http://fichiers3.touslesdrivers.com/405 ... 0.3408.zip (don't get them from the Intel mirror; the download is missing) and enjoy QSV.

Can you please check whether you see any of these warnings in your log with a working driver?

Edit: nevermind, saw viewtopic.php?f=9&t=29724

Still, anyone seeing BPyramid-related messages in your logs on Silvermont (Bay Trail, more or less) hardware, please report it.

These appear to be the same drivers as the ones I linked to a few posts up (https://downloadcenter.intel.com/Detail ... ldID=23636).

Unfortunately, I'm still seeing low frame rates & high CPU usage with nightly build svn6117.

Re: Poor QSV performance on Intel NUC DN2820FYKH

Hmm, I have a guess as to what's going on.

ARK | Intel® Celeron® Processor J1800
ARK | Intel® Celeron® Processor N2820

Unlike the J1800 used by kvaruni, the Intel ARK website indicates that the N2820 processor does not support Quick Sync Video. However, since the encoder was detected as available, my original assumption was that either of the following applied:

- the Intel ARK website was incorrect for some reason, and the processor does in fact support QSV
- the graphics driver was buggy and used a code path meant for another processor/GPU combo

Now, looking at your first post (80% CPU usage and B-pyramid used even though the implementation supposedly doesn't support it), I have another theory: Intel Quick Sync Video is indeed NOT supported on your processor, and the graphics driver is using the hardware implementation…'s fallback software implementation.

If that theory is correct, you'll need a new processor is you want hardware-accelerated QSV encoding.

Thanks Rodeo. The results of running 'C:\Program Files\Intel\Media SDK 2014 for Clients\tools\mediasdk_sys_analyzer\mediasdk_system_analyzer_64.exe' seem to support your theory:
