Playback of any 2160p HEVC HDR video file (on an SDR display) results in a static green screen output. H264 SDR files play normally.

Using vo=mediacodec_embed will display video.

Formuler Z10 Android TV box
Mali-G31 GPU

the hdr hevc 2160p videos play normally in VLC

setting vf=format=yuv420p as per #198 makes no difference

Hmm. Hard to say what's wrong here.
Does it work in vo_gpu?
Does it work with SW decoding mode?

[IzanagisBurden]

with vo_gpu, the behavior is the same (green screen, although dimmer)

I believe sw decoding works, but for the files I tested (4K HDR) I think the CPU was too slow to display an image. I also tried with a 4K SDR 8 bit HEVC file and I was getting some frames displayed.

One thing I noticed as well is that it displayed 1080p SDR HEVC 8 bit content and 1080p H264 8 bit but image appeared glitchy, as if certain rectangles of the image glitched/overlapped other parts of the image.

Additionally, I tried MX Player Pro and all my files played normally and it reported HW+ decoder being used.

Same here, on a RK3588 box all HEVC and VP9 videos show green screen when using "HW" decoder (i.e. mediacodec-copy).
It works with "HW+" (i.e. "mediacodec"-non-copy) though, but it's kind of meaningless for HDR content cause there's no tone mapping in this case. "SW" works too but the device just can't handle 4K HEVC in sw mode.
Same behavior on gpu and gpu-next.
