STATUS:
drm hwaccel working with hantro (mpeg2, vp8, h264) and rkvdec (vp9, h264 8+10bit, h265 8+10bit)
ffmpeg 4.2.3 with v4l2-request-hwaccel-4.2.2-rkvdec patch working well, except decoders listing is broken (i.e. mpv and others will be broken)
kodi supports all hantro and rkvdec hwaccel, including plugins (youtube and jellyfin confirmed) *see kodi-git thread*
gstreamer supports vp8 and h264 via v4l2codecs in gstreamer-plugins-bad
vaapi hwaccel working with hantro (mpeg2)
firefox 75 supports initial vaapi on wayland, v76 expands vaapi support to all supported codecs, no X11 support
chrome supports vaapi with unofficial patch that will never be upstreamed, but included in some linux distros (fedora, etc.)
