x265 3.0 Dolby Vision encoding

[quietvoid]

No way currently, but it could be possible with reference XML and binary RPU.
Sol Levante only comes with one of those, since Netflix doesn't openly distribute the transcoded files.

Same answer for HDR10+, but that's more complicated.

I'm not sure how your usecase has Dolby Vision support in Resolve (requiring a license), but not the DEE.
Maybe they come separately.

You could use a public cloud offering like AWS MediaConvert or Hybrik to do this indirectly. Either would produce final Dolby Vision Profile 5 elementary streams (with the RPU included). You could dump that data if you just wanted the RPU.

Actually, Netflix does make some of their experiments available as both XML and encoded metadata.
So it could be done pretty simply, if someone does the work.

Yeah, for that this patch should be applied, but the speed of the devs, oogh! https://patchwork.ffmpeg.org/project/ffmpeg/patch/CAGKSLywdGwJ=B1fa_1Ns5Ac-ZaxecB7PUFuiTYnNFA9=+NYF-A@mail.gmail.com/

This patch is so important I can't even :) ^^

Hi all,

Is there a way to convert plain-text XML (from DaVinci) to binary RPU file metadatas without using the expensive Dolby Encoding Engine software?

Or maybe a way to convert a JSON file from HDR10+ to this binary RPU?

Thanks.

I've started working on this, you can find a test build here: https://github.com/quietvoid/dovi_tool/pull/43
edit: Feature is in 0.5.0: https://github.com/quietvoid/dovi_tool/releases/tag/0.5.0

So far L2 trim values seem to be different for Netflix's Sparks encoded RPU.
I don't really know why.

Also, I recently added partial generation from HDR10+, essentially just using the analysed L1 metadata.

Edit: now supports both CMv2.9 and CMv4.0 for L1/L2/L3/L6 metadata.

Great news! I'll give it a try.

Our HDR playback files are created using the HEVC (H.265) video codec, so make sure that you are using a supported video player and HDR10 supported viewing hardware. We recommend using the nightly build of VLC (https://nightlies.videolan.org/) or mpv (https://mpv.io/installation/).

Only apple devices are supported and Youtube-dl ;)
