12Bit colour support

[OnyxUK 84]

hey just a question does emby support 12bit colour ?

Hi, I think it's more of a question of what your devices support, no?

[OnyxUK 84]

well some of mine do, hence the question lol

In many cases Emby apps rely on platform video players, in which case there's a good chance it will just work when direct playing. If the server is transcoding, then we haven't yet done any 12-bit specific work.

oh okay that helps alot i am using them as transcodes of some so that explains a lot, thank you

I'm afraid, but the conversation above has gone in a somewhat misleading direction.

First of all, the question cannot be asked like that. 12bit - yes/no is not a valid determinant.
Video formats support color formats and color formats can be 8, 10, 12, or more bits wide.

Examples for 12bit color formats are YUV420P12, YUV422P12, YUV444P12, YUV440P12

So, a valid question would be like: "Is HEVC video with YUV422P12 supported?"

The Emby client app still needs to decide or "know" whether it can play such formats, so it might not always work right out of the box.

We haven't widely tested such formats yet. But in general, no specific work is needed for being able to process these. We know the color formats that hardware decoders can process and when no hw decoder can handle it, the server uses software decoding from ffmpeg, which can handle virtually all color formats conforming to the codec specs.

 

What specific video format do you actually have?

hey thank you for the detailed information, this has helped with my main question and to yours, it would be h.265 hevc YUV420P12 & states in media info that the format profile is format range@4@main

these are the range extension profiles. If you have modern hardware (Nvidia or Intel), then it might also work with hw decoding. Might - this is still a non-common case area..

yeah i have modern hardware, i am running the server of a amd Ryzen 9 5950x CPU and Nvidia RTX 3090 extreme
