Hello,
Did you know that Zgemma developers start to improve driver for Set Top Boxes based on the HiSilicon chip? For example Zgemma H9S?
I just checked 4K 3840x2026 with VP9 codec from YouTube via exteplayer3 and works well.
I also checked "jellyfish-120-mbps-4k-uhd-h264.mkv" H264 4K and works well.
There is still some problem with seek/jumps on the HEVC TS and sometime after pause there is problem with resume.
But with these new drivers you will see really huge improvements with playback via the exteplayer3 and gstreamer based solutions.
I'm going back to testing ![:)]()

Regards,
