Choppy video on Intel NUC NUC5PPYH with Netrunner 17

Hello,

I recently bought a new Intel NUC Kit NUC5PPYH to use as a desktop pc. The configuration is below:

Processor - Intel Pentium processor N3700 (2.4 GHz Quad Core, 6W TDP)
Memory - 8GB DDR3L SODIMM 1.35V, 1600 MHz
Graphics - Intel HD Graphics
Storage - 128 GB SSD
Display - Samsung 40-in SmartTV via VGA

I installed Netrunner 17 and Windows 10 in a dual-boot configuration. There were no issues during installation. While exploring NR 17, I noticed that videos were very choppy. The video and audio held sync but the picture was so choppy that I’m unable to watch a live concert (with strobe lights) without getting irritated. I tested the same video on Windows 10 (with Intel graphics drivers installed) and it played flawlessly.

Could someone help me resolve this issue?

Thanks,
opopanax

Have you installed any of the VA-API and libva support packages for video acceleration on your Intel chip?

No, I haven’t.

Picking up on your suggestion, I went to https://01.org/linuxgraphics/downloads and http://freedesktop.org/wiki/Software/vaapi/ websites. Do I need packages from both sites installed on my system or will one of them suffice?

The first site lists the package “Intel Graphics Installer for Linux* 1.2.1” and the second one lists the below stuff:

Broadcom Crystal HD (work-in-progress): http://gitorious.org/crystalhd-video
Intel Embedded Graphics Drivers (IEGD): http://edc.intel.com/Software/Downloads/IEGD/
Intel Embedded Media and Graphics Drivers (EMGD): http://edc.intel.com/Software/Downloads/EMGD/
Intel GMA500 driver (OEM only): https://launchpad.net/~ubuntu-mobile/+archive/ppa
Intel integrated G45 graphics chips: http://cgit.freedesktop.org/vaapi/intel-driver
IMG VXD375/385 and VXE250/285 video engines: http://cgit.freedesktop.org/vaapi/pvr-driver/
VDPAU back-end for NVIDIA and VIA chipsets: http://cgit.freedesktop.org/vaapi/vdpau-driver/
VIA / S3 Graphics Accelerated Linux Driver: http://www.s3graphics.com/en/index.aspx
XvBA / ATI Graphics Backend (for proprietary driver only): http://cgit.freedesktop.org/vaapi/xvba-driver/ Other back-ends are currently under development.

These should already be in the repositories, just search for libva and vaapi.

Ok thanks, I’ll try them out.

Sorry about the late reply.

I checked for those packages and found that they were in fact installed. I re-installed them, rebooted and then checked. The videos played fine. However, there is an intermittent annoying flickering at the top of the screen. It sometimes happens when I’m scrolling a page in the web browser or even when playing videos. I read it has something to do with Plasma 5 (which in fact did crash once or twice till now).

I need one more help. Not sure if I need another thread for this. I need to lower my screen resolution from 1080p to 720p. The reason is that I’m using a 40-in TV as my display and I sit about 4-5 feet away from it. I don’t see an option in the System Settings that would allow me to bring down the resolution. The Display section usually has a drop-down menu for changing the resolution but mine shows resolution as 1920x1080 with no menu. Could you please tell me how to change my screen resolution? For the time being, I’m using “xrandr -s 1360x768” because 1280x720 does not show in the xrandr output.
