Description
Intel Quick Sync Video supports JPEG encode acceleration on Braswell and later. (2016)
JPEG is critical to the performance, especially for the HTML5 client. Let's see if this beats libjpeg-turbo.
Chrome uses it: Chrome Working On JPEG Encode Accelerator With VA-API/V4L2 Support, so that's likely to be a win.

Even trying the ffmpeg qsv command line examples fails.
Probably requires that I unplug or turn off the nvidia card and switch back to the intel iGPU. (Intel® HD Graphics 530
found in the i6700k)
libva (#451) might be a better option: it is more generic, supports amd and nvidia too, and this does look like it might work without touching the hardware:
