Hi,
sorry to jump in on this thread, but I recently also tried to play hardware accelerated video (preferably on a virtual terminal without X11/Wayland) on my Pine A64 with current Armbian image (derived from Ubuntu 23.02). Unfortunately no method seems to work. Am I doing something wrong? What would be the "easiest" way to get mainline hw accelerated video decoding on A64? Is there another popular general purpose distribution I could try (except LibreELEC with Kodi)?
Kernel is 5.15.93-sunxi64 and has cedrus modules:
lsmod | grep cedrus
sunxi_cedrus 49152 0
videobuf2_dma_contig 24576 1 sunxi_cedrus
v4l2_mem2mem 36864 1 sunxi_cedrus
videobuf2_v4l2 24576 2 sunxi_cedrus,v4l2_mem2mem
videobuf2_common 49152 5 sunxi_cedrus,videobuf2_dma_contig,videobuf2_v4l2,v4l2_mem2mem,videobuf2_memops
videodev 204800 4 sunxi_cedrus,videobuf2_v4l2,videobuf2_common,v4l2_mem2mem
mc 49152 5 sunxi_cedrus,videodev,videobuf2_v4l2,videobuf2_common,v4l2_mem2mem
Gstreamer is version 1.20, and it seems to have provide required codecs (after installing gstreamer1.0-plugins-bad).
gst-play-1.0 --version
gst-play-1.0 version 1.20.1
GStreamer 1.20.3

Unfortunately gst-play doesn't work, it completely freezes my Pine64 (not even Ctrl-Alt-Delete works anymore) after "Redistribute latency...".
gst-play-1.0 bbb_sunflower_1080p_60fps_normal.mp4
Kodi 19.4 from apt repo also doesn't play hw accelerated (although it should as mentioned in post #1), on start it prints this error:
$ kodi
libva info: VA-API version 1.14.0
libva error: vaGetDriverNameByIndex() failed with unknown libva error, driver_name = (null)
mpv also doesn't work:
$ mpv bbb_sunflower_1080p_60fps_normal.mp4

mplayer also competely freezes the Pine A64 (like gst-play).
But ffmpeg even seems to have necessary decoders?

Needless to say ffplay also doesn't work. When forced:

So what is going on here? Am I missing a package or kernel module (concerning drm?)? Or do I need an ffmpeg with `--enable-v4l2-request`? And/or an libva-v4l2-request? Where do I get one that compiles with kernel 5.15?
Thank you!
