x265 and Dolby Vision
Hello, is it possible today to encode a UHD Dolby vision in x265?
If so, I would like to know the method. I tried by extracting the 2 Dolby layers (BL + EL). The BL being the main layer with the video and the EL mainly containing the specific dolby meta if I understood (afterwards I only had a Dolby UHD available). I tested by encoding the BL layer and giving the dolby-vision-rpu the EL file. - it does not work rpu non-compliant. I tested without dolby-vision-rpu. -it does not work. I tested by 'merging' the BL + EL with the 'yusesope' method and encoding this track BL_EL.hevc without dolby-vision-rpu. -it does not work. Mistake : x265 [error]: x265_encoder_open () failed for Enc, aborted at input frame 1, output frame 0 in x265 So we have to do a mkv remux of the UHD dolby vision, then extract the video track (as usual when we do standard hdr versions), and encode this video track by specifying just the –dolby-vision-profile? thank you in advance |

I don't know if this is going to help you. But after backing-up the Dolby Vision version of 'The Fifth Element', I noticed the following 'Encode Settings: -

These are the relevant command line parameters: --dolby-vision-profile <integer|float> Generate bitstreams confirming to the specified Dolby Vision profile, note that 0x7C01 makes RPU appear to be an unspecified NAL type in HEVC stream. If BL is backward compatible, Dolby Vision single layer VES will be equivalent to a backward compatible BL VES on legacy device as RPU will be ignored. The value is specified as a float or as an integer with the profile times 10, for example profile 5 is specified as “5” or “5.0” or “50”. Currently only profile 5, profile 8.1 and profile 8.2 enabled, Default 0 (disabled) --dolby-vision-rpu <filename> File containing Dolby Vision RPU metadata. If given, x265’s Dolby Vision metadata parser will fill the RPU field of input pictures with the metadata read from the file. The library will interleave access units with RPUs in the bitstream. Default NULL (disabled). CLI ONLY And for Profile 8. --dhdr10-info <filename> Inserts tone mapping information as an SEI message. It takes as input, the path to the JSON file containing the Creative Intent Metadata to be encoded as Dynamic Tone Mapping into the bitstream. Click here for the syntax of the metadata file. A sample JSON file is available in the downloads page --dhdr10-opt, --no-dhdr10-opt Limits the frames for which tone mapping information is inserted as SEI message. Inserts SEI only for IDR frames and for frames where tone mapping information has changed. |

According to the MediaInfo report I posted above, the 'dual-layer' element of the Dolby Vision file was encoded using x265 3.2+20-a4e060a44839:[Windows][GCC 6.3.0][64 bit] 10bit. Cheers

So to do things right from a UHD Blu-ray: you have to make a backup with MakeMKV by combining the two original video tracks into one track. Then we encode this video track in x265 (BL + EL + RPU). ? Quote:
Personally I tested Davinci Resolve, I was able to create a Trim Dolby vision meta file but it is in xml and given what is in it I doubt that it is the dynamic dolby vision data, there may be too much. . Last edited by ghostshadow; 29th September 2020 at 10:59. |

It is certainly possible to use x265 to encode the two layers, like you can encode anything. x265 just doesn't have built in support, so other operations in other software needs to be performed before and after.

And just to confuse matters further. There are two different enhancement layers.
MEL = 10-bit minimal enhancement layer (encoded at 2Mbps or below) FEL = 12-bit full enhancement layer (encoded at 3Mbps or much, much higher) --------------------------------------------------------------------------------------------- Edit: And for anyone who's not tried it yet... When you re-mux the secondary (1920x1080) Dolby Vision HEVC video stream/layer into either the .mkv or .m2ts container and play it in either a software player or hardware playback device. A MEL encoded video stream looks like this: ...but a FEL encoded video stream looks like this: Cheers

i used yusesope tools to combine the Bl + the El into one. After I made an iso with TsMuxer, then I extracted the x265 to encode it
for the rpu Trim Dolby vision 7 ko for the xml Last edited by ghostshadow; 29th September 2020 at 21:46. |

he two video tracks are encoded. I don't quite understand. I thought there was only the base layer to encode. |

The older two layer profiles used a base layer and an enhancement layer combining both a video bitstream and metadata. |

I am using MakeMKV and the 'save' option does not modify the files and ESPECIALLY does not encode ..... The mediainfo you post shows an Hdr10 encoding there is no dolby vision Last edited by ghostshadow; 1st October 2020 at 07:22. |

The .m2ts file in the second report I posted was extracted directly from 'The Fifth Element' (StudioCanal) 4K UHD disc - Which looks beautiful by-the-way

In FEL, it stores the delta from the decoded base layer and the original 16-bit TIFFs. (12-bit is derived from the 16-bit TIFF) Dolby recommends 8 Mbps avg and 15 Mbps peak for FEL. You can encode the base and EL with x265, I have. And then you use either Dolby Encoding Engine (DEE) or their SDK to do the rest. It is a multi step process. The XML from Resolve is used in conjunction with the 16-bit TIFFs to generate an RPU binary file. The XML contains image statistics, trim pass and aspect ratio information. Additional metadata is pulled from the TIFFs. Last edited by Stacey Spears; 1st October 2020 at 20:10. |
