With hwupload and color_range full:  And this is how i expect it to be (provided pix_format p010 and removed hwupload)

Ahh, i see what you mean! Interesting how banding (the lack thereof in fact) fooled me in this instance. It indeed has `yuv420` as output format when passing `bgr0`. I...

Ok, will do! I do have to modify more. Even to get logging. Because.. errr... ``` ❯ cppgrep "log_to_dbg" libavcodec/amfenc_hevc.c:109: { "log_to_dbg", "Enable AMF logging to debug output", OFFSET(log_to_dbg), AV_OPT_TYPE_BOOL,{...

Right, nope. This is a little more involved then just enabling one little thing.. We're now in AMF vtable and initialization magic. I'll happily apply a patch if you have...

Ha! You use god mode? That's not documented! AMF_ASSIGN_PROPERTY_INT64(res, ctx->encoder, AMF_VIDEO_ENCODER_HEVC_OUTPUT_COLOR_PROFILE, AMF_COLOR_PRIMARIES_BT2020); Note the **primaries** in the **color profile** 😉 Anyhow, confirmed locally! Thank you for these values. Is there...
