Summary0000129: Support for HEVC decode and/or encode hardware acceleration
DescriptionDoes Cinx-GG support hardware accelerated graphics for decode and/or encode - and if so, how to set it up?

1) Dell XPS 13 (9370)
Quad core Intel Core i7-8550U (-HT-MCP-) cache: 8192 KB
Card: Intel Device 5917
Display Server: wayland (X.Org 1.19.6 )
driver: i915
Resolution: 3840x2160@59.98hz
OpenGL: renderer: Mesa DRI Intel UHD Graphics 620 (Kabylake GT2)
version: 4.5 Mesa 18.0.2

On this machine I can load and playback UHD-H265 video (recorded on a Pixel3 phone) with the Totem and the Dragon video players. Cinx won't load or playback this video (appears as single-threaded as previous mentioned).

2) ASUSTeK model: Z170-A (Skylake)
Quad core Intel Core i7-6700K (-HT-MCP-) cache: 8192 KB
NVIDIA GK208B [GeForce GT 730]
Display Server: x11 (X.Org 1.19.6 )
drivers: nouveau (unloaded: modesetting,fbdev,vesa)
Resolution: 1920x1080@60.00hz
OpenGL: renderer: GeForce GT 730/PCIe/SSE2
version: 4.5.0 NVIDIA 390.87

None of the standard video players, Totem, Dragon or VLC is able to playback the recorded UHD-H265 video.
Cinx won't load or playback this video.

I thought there was a chance if ffmpeg could do it. By the way, it would be useful if possible to get clarified the difference between the supported X11-OpenGL accelerated playback (effects done in hardware) vs. hardware accelerated video decoding ;)

No, it does not support it. Not sure if it ever will. If gg has more to say on this subject, I will report back.
