Dolby Vision now possible through MP4 Mux.

Strangely, The Black Phone Movies Anywhere P5 web-dl has two frames on V4.x and the rest on V2.9

Most Movies Anywhere samples I looked at were like that.

Got a cmv question?
Let’s say master move was done in cmv2
When that master churns out a p5 I assume it’s now cmv4, I’m I correct in saying most original P5s are cmv4 this is what I’m seeing on my end please correct me if I’m wrong.

Packing P8->P5 only changes profile. All the RPU data won't be changed. CM version will also not change. If that's what you are asking.

Please can you share your latest kodi build for Firestick?
Many thanks.

This is the last I built: https://mega.nz/file/NN9GADIL#8aizfPA8M ... k6_PNiTLJc

Thanks a lot.

[sw5163]

no, most movies are V2.9 (95%+)

Do you have a file with a lot of cmv40 data?
According to saindriches, cmv4 seems to have a problem on Apple platform. I want to give it a test but I don't know what file is FEL with cmv40.

you can check out the movie Hitman's Wife's Bodyguard. And I think you can remove cmv4.x with the dovi_tool

Also Plex triggers Dolby Vision playing Profile 8 ts movies. Is it fake or real DV?

One possible way to find out is to remux those sample files provide by quietvoid.

You can try the files here: https://mega.nz/file/xNcAVQhJ#ldoifbK6D ... dXkzw2HYgs

Im guessing tsmuxer can mux them to P8 ts, but I don't know how.

Those files, provided by @quietvoid are mkv.
So I remuxed them in Ts muxer.
In Plex both mkv and ts remuxed files do not work. No rpu.
So, to answer my question, P8 ts files in Plex are fake DV.

ok so
fake p5 TS = no go
p8 ts =no go
p8 mkv = no go as well I guess?

one last thing to try,
fake p5 mkv: https://drive.google.com/file/d/1H_edhc ... sp=sharing

The file cant be played in Plex.

Is it possible to decode and play Dolby Vision movies on a PC monitor?

For example, the Alienware AW3423DW (34" Ultrawide, QD-OLED, "HDR") doesn't support Dolby Vision but can software decode the Dolby Vision and display it instead of having the monitor decode it?

Not completely supported as if it was played in real Dolby Vision.
At best you can playback profile 5 in HDR10, with no extra dynamic tone mapping using the metadata.

mpv supports partial processing of profile 7/8 as well, but that might be inaccurate in comparison.
As the processing isn't complete (FEL, for example).

Sorry could you please explain more of this? Is it still HDR10 when RPU levels can make a difference?
Can windows have the correct display brightness and pass that to DV extension and produce proper tone mapped image? In that case, would it be equivalent to HDR10+?

[quietvoid]

Sorry could you please explain more of this? Is it still HDR10 when RPU levels can make a difference?

The dynamic metadata from the RPU isn't used, so what you get as output is HDR10 + whatever processing your video player does.

Can windows have the correct display brightness and pass that to DV extension and produce proper tone mapped image? In that case, would it be equivalent to HDR10+?

No, you have to rely on your player to do the tone mapping, or the HDR10 passthrough.

Sorry I’m a little confused, what do you mean by “dynamic metadata”? RPU level in your samples make a difference on DV extension on windows. Is there something more in p8 RPU besides null reshaping and those levels? I thought if I can see dynamic brightness change it will be dynamic mapping. Maybe I’m wrong, which I always am.
What’s the difference between let DV extension handle mapping(if it works correctly) and proper lldv?

Guess fake P5 mp4 will be the only way.
