If I have an m2ts file with 2 layers and HDR10 PLUS Dolby Vision but the TV only recognizes HDR10, is there a way to force Dolby Vision somehow?

If there is metadata for multiple HDR standards, the TV decides which HDR format to use. If it has a choice between HDR10 (static HDR) and Dolby Vision (dynamic HDR), it will certainly choose Dolby Vision.

Yeah well but it doesnt. MKVToolNix shows 2 streams one with 4k and one with 1080p. Ofc thats not really accurate cause MKVToolNix doesnt support Dolby Vision but both standards are there. The TV doesnt play the m2ts.

So I have to convert the m2ts to mkv which THEN only seems to support HDR10.

As an example this one: http://4kmedia.org/lg-dolby-vision-uhd-4k-demo/

Once I've used MKVToolNix, the Dolby Vision is gone

Is there at least a way to see if I am using Dolby Vision or not? The TS and the MKV files look pretty much the same in MediaInfo for example. But one has DV the other doesnt....

are you sure your TV supports Dolby Vision or 12-bit in general? From what Ive read most panels dont.

12 bit doesnt matter atm. No TV supports that, thats true.

I got an LG Oled B6. All these Oleds support Dolby Vision. So as I said the TS file has DV and it works fine! After using MKVToolNix, cause the program doesnt support DV, Dolby Vision is gone from the MKV.

But still some information wether the file has DV or not would be nice. But MediaInfo, nor MPC or VLC or any program show anything regarding Dolby Vision....its like it doesnt exist yet. Unfortunate

This entire discussion is rather off-topic for the x265 thread, since x265 cannot encode Dolby Vision, nor is it in any way related to handling your existing Dolby Vision files.

Hi... how can I use extracted Dolby Vision Enhancement layer to encode it to HEVC stream directly with x265?

Why do you add a question about eac3to to a thread specifically discussing the development of x265? Stay in each thread, separately, please.

@jlpsvk: I directed that to d3rd3vil. Being interested in enhancing x265 is a valid intention here. But using eac3to is best discussed in a thread about eac3to, instead. And there I already expressed my doubts that eac3to is the first choice software to treat video streams, because it was originally made to handle audio streams.

Yeah. Ok. But. Can I use the demuxed Dolby Vision stream and mux it to encoded video with x265? in MKV new eac3to (3.22) is recognizing Dolby Vision Enhancement Layer too.

x265 has no support for anything Dolby Vision, you would need external tools that support this, including writing the required metadata for Dolby Vision.

All dynamic HDR requires external tools to analyze the color volume of the video, frame by frame, saving this metadata to a file. For example, Samsung contributed code to x265 enabling us to parse this metadata and insert it into the HEVC bitstream as SEI messages. We are always working with partners in the video ecosystem to find ways to make these kinds of integrations easier and more reliable for our mutual end-users.

No. MKV has no support for Dolby Vision. Not to mention the additional metadata to even identify the streams as Dolby Vision.

@x265_Project, is it possible to have metric data, such as SSIM scores put into the media info like the encoding settings are?
