Do you have at hand a 4K mkv that is known to work to get 2 seconds from it? I used the following command to extract 3 seconds, where `-ss 2665` is the start second and `-t 3` is duration

ffmpeg -i input.mkv -ss 2665 -t 3 -acodec copy -vcodec copy output.mkv

[WanWizard]

No, sorry, I don't have any downloaded files here, don't even have the time to watch "regular" TV, or my stack of recordings...

@serdeliuk;

 

 

Its normal because of samsung tv's have no licence for dolby vision 

 

You have a film including DOLBY VISION (DOVI) color palette.

 

Unfortunately;  Samsung has never bought dolby vision licence for a long time.

 

You see blue color as green in dv or dovi film.

[WanWizard]

The same problem exists on all other TV's, also non-4K ones, with all sorts of box brands, and when played on the PC using VLC.

I think this is partial right, but it depends on the decoder in my case my pc or solo4k i suppose, so it seems that we need a newer ffmpeg, at least on my pc, going to try to get a newer one

It doesn't matter!

 

Dolby Vision has a different color palette and New born.

 

Only the high end tvs have this feature.  

The real dovi tv must be at least 1500 candela.

 

I prefer SDR format(yuv-4.2.2) on 4k films.

Most of 4k tvs(cheap ones) has fake HDR,HDR10 and HLG capabilities.     

 

I captured the same film and similar scene.

The real color is orange.

Open.Matte

Upscaled.AI  (Old films upscaling to 4k)

So, if i get an expensive TV that supports Dolby Vision and play the movie from my computer via HDMI (mirror) on my computer will have the colours scrambled but on the tv will be correct? My computer seems to have a Dolby VIsion compliant video card, cheap but compliant, iRiS xe, but does not want to correctly play that thing, tested in windows or linux, does not make any differences.

Please be careful if you want to buy a tv with dolby vision support.

 

No matter how the source is.

I use 4k receiver to watch films.

I use tv as if pc monitor.

I do not know DV Compliant video card on pc side.

 

My dream tv is here

https://www.displays.../model/18402a96

 

I tested it several times.  Candela,colors,IMAX,BMatte,Sound,etc are near perfect.

[serdeliuk]

I am still not convinced that the DolbyVision is the issue here, i can play all the samples provided by Kodi here https://kodi.wiki/view/Samples

[Jork]

So no doubt your TV set is also able to play the DolbyVision content with Kodi?

I have a mediaplayer which is capable of playing DolbyVision content but my 4k LG HDR10 projector isn't.

The shield tv mediaplayer doesn't indicate it is a Dolby Vision ready device.

On a tv set which is capable it does.

I am using for now only my PC, to exclude any solo4k or TV issues, the sample provided earlier do not work well on my PC either, but the samples from Kodi works well on my PC.

[kamaxx]

Good Evening;

 

 

Dolby Vision tone mapping (color space-color palette) is different to normal SDR (standart dynamic range) color system.

 

If a mediaplayer machine has hardware based Dolby Vision VS10 Engine Board  (Some rdt1619dr chip) then convert color system to normal led tv.

 

But anther problem is dolby vision profile level.

 

DV has profile levels From 4 to 20.  These mediaplayers can only convert some levels.

 

Usually 4K Films are profile 7,8
