We’ve already written about future processors that will support 8K video decoding, such as Rockchip RK3588 that is expected to launch in early 2020.
Amlogic Video Engine (AVE-10) offloads the Cortex-A53 CPUs from all video CODEC processing. It includes dedicated hardware video decoder and encoder. AVE-10 is capable of decoding 4Kx2K resolution video at 75fps with complete Trusted Video Path (TVP) for secure applications and supports full formats including MVC, MPEG-1/2/4, VC-1/WMV, AVS, AVS+, AVS2 RealVideo, MJPEG streams, H.264, H265-10, VP9 and also JPEG pictures with no size limitation. The independent encoder is able to encode in JPEG or H.265/H.264 up to 1080p at 60fps
There’s only mention of 4Kx2K decoding at up to 75fps, and further down in the document, we can see VP9 maximum resolution and framerate:

So is that fake news? Apparently not, as adamg managed to play an 8K 30 fps video with CoreELEC on Amlogic A311D powered Khadas VIM3 SBC, and he has a video to prove it.
The VP9 video has a 7680×4320 resolution and a 29.970 fps framerate. It appears to play relatively smoothly. While Amlogic A311D supports HDMI 2.1, I doubt it can output 8K, so I’d expect 8K video decoding to work, but not 8K video output. I asked whether the video output in the video above was 1080p or 4K, but I did not get an answer to that specific question, and instead was told Amlogic S922X-B SoC, the faster version of S922X, can also handle 8K VP9 video decoding.
