HEVC / x265 content won't play or with green artifacts
#1
Hi,

Both Kodi 16.0 and 16.1 (haven't tried it before with 15.x) won't play HEVC/x265 content. Kodi will either crash or play the file while stuttering and showing green artifacts all over the screen.

I'm running Windows 8.1, Celeron N3150 (Braswell) with On-Board Intel HD Graphics and 8 GB RAM. The board should have built-in x265 decoding.

Any idea how to fix this?

Rgrds,

Bento

Seems it's related to the movie that you are trying to play.

No, different files and they all play fine in VLC on the same machine.

Be careful there are videos encoded in H264 10bits format available.

This is unofficial format and will never fully hardware even in modern chipsets. It must played in software encoding but it will cause high CPU processing.
Only h264 8 bits and h265 10 bits are supported because they're official.

h264 10bits in hardware mode will cause green or another false color big pixels in videoplay, and it can shutter too.

The big difference between VLC and Kodi is that default in VLC is software rendering, while in Kodi the default is hardware, try changing your rendering to 'software'.

Will try tonight. My HW should be able to do 265 decoding though.

The only 10-bit HEVC decoders are found in the Nvidia GTX 960/950.

Could be an Intel video chipset/driver issue, too. I've moved almost exclusively to x265 encoding and had some issues initially with my htpc at the time, which had Intel Iris Pro onboard graphics. When I decided I wanted a more powerful gaming/htpc machine and built a new computer with a Geforce 980ti card all my rendering issues went away. Might be worth seeing if there are newer drivers available for you from Intel's website.
Windows 11 Pro, Kodi 20, AMD Ryzen 9 5900X, 32gb RAM, nVidia 3080 ti
