Has anyone had success in hardware decode of the Astra 8K satellite channel? My system plays it like a slide show using cpu decode with Intel GPU and Kodi 18.3 and my AMD RX480 with VLC Nightly cant handle it either.
Codec Details are as follows:
Codec: MPEG-H Part2/HEVC
Video Resolution: 7680*4320
Frame Rate: 50.0
Colour Primaries: ITU-R BT.2020
Colour Transfer Function: Hybrid Log-Gamma
Bitrate is around 80Mbit
I'll repost my image from the coreelec forums
I can play it fine on my windows machine with HW decoding

Awesome. Whats the hardware?
Guess that means only Nvidia supports 8K decode right now. Recentish AMD and Intel fail.

My nothing special i3 7th gen laptop was having a good go at playing it in MPC HC without me looking at optimising it. I think 8K HEVC decode is not that unusual in current GPUs?
For info this is the full Media Info report on it (though I made the recording using ffmpeg from a network stream so the PIDs may be different). They are using a strange 1.0 centre-channel only audio stream - unless there is some odd-ball audio that is falling back to this?
