Support UHD HDR x265 10Bits -> too black #86

Open G-eos opened 3 years ago

G-eos commented 3 years ago

Hello, Thanks for the great job done. When I play UHD HDR x265 10Bits the video is too black.

The support seems not assured: https://jellyfin.org/docs/general/clients/codec-support.html But is works .. but with a video which is too black.

Is it a matter of TV HW which does not do the job, or only a configuration/parameter which is not done (yet). Thanks for your hint on where can I start to debug it, or better a fix that I would test with pleasure ;-)

TV HW is QE65LS03RAUXXC

Server Jellyfin 10.7.2 TV Application has been built 22 march 21. I do not see any commit that fix it, but may I am wrong.

Stream: Stream #0:0: Video: hevc (Main 10), yuv420p10le(tv, bt2020nc/bt2020/smpte2084), 3840x1608, SAR 1:1 DAR 160:67, 23.98 fps, 23.98 tbr, 1k tbn, 23.98 tbc (default)

Thanks

First of all, does it play as DirectPlay? If so, only the TV (HW, settings) is involved.

I will check it precisely, but yes it is what I feared. I will put too on a USB stick to test "directly" on the TV. Does tone mapping is an option. Like expressed https://github.com/jellyfin/jellyfin/issues/415 and https://github.com/jellyfin/jellyfin/pull/3442 ?

Does tone mapping is an option.

I haven't tried it, but maybe (if there is no other way). It requires transcoding, so I think it is better to achieve direct play (or direct stream) with the desired picture (since your TV supports HDR). At least on my UE65NU7400 I see some difference (brighter colors) between HDR and non-HDR.

The TV appears to support HDR : https://www.displayspecifications.com/en/model/c0541953 when I play it directly from an USB stick. The HDR "logo" is displayed but the picture is "dark" as whith Jellyfin.

I do not find any settings :-( If you have any hints to where I can dig I will appreciate. If not, I will remain in non HDR. It comes usually with h265 ...

I've noticed that some Netflix content is really dark on my RU8000. IIRC they were listed as HDR. Im guessing the issue is a bug in Tizen since it happens on different HDR-ready TV's.

This can be fixed by settings npl to 60 instead of 100 in MediaBrowser.MediaEncoding/Encoder/MediaEncoder.cs

Disabling all fancy TV setup to adjust the backlight versus ambiant / eco mode / ... lead to do not have anymore the issue !

Too smart is not always the best setup. :-)
