Dolby Vision Content and latest MPV Player.

PotPlayer x64 with SVP 4 work DoVi

if you expect this to work in Plex - don't

with the plain mpv - why shouldn't it work with SVP enabled?

It must work. In PotPlayer, leave the video viewer on automatic. Because if you set it to Direct3D11 manually, the image turns purple. Automatically set it to Direct3D9 and you can enjoy the Dolbi Vision effect on your PC. Miles different than a normal bluray movie. More vivid and clear, more realistic. This little add-on I linked to allows it to work in the built-in media player, MPV and PotPlayer under windows 11. You can also install Dolby Vision sound, but it's paid for in the Windows store, so I'm not linking to it, not advertising it, just that you can set up PotPlayer to get the DV sound effect you want. Working in conjunction with SVP, PotPlayer can provide the frame rate to match your monitor, and if you're using an HDR monitor, 10-bit colour depth. (I'm not a professional user and I'm not a tester, I'm just an average IT guy who likes to watch movies with his family in the best picture quality in the evening.)

yes

Hi, great news it works great with MPV
I have a couple of questions though :
1/ Is this real dolby vision decoding and converted on the fly to standard hdr with preserved dynamic metadata ? because the previous solution with madvr wasn't able to decode dolby vision, it was "just" an hdr optimization with frame by frame analysis and static hdr metadata. Also full dolby vision support requires an additional hevc decoder to decode the FEL layer (full enhancement layer) but very few movies carry it.
2/ Is MPC-HC compatible with this solution ? I have read that it requires to use the new libplacebo from ffmpeg

EDIT : I don't understand the use of it. From the reddit post "So the special DV/HDR10+ dynamic scene by scene metadata will get lost/ignored, but i'm not even sure those are used much outside of testfiles?". It is just a fallback solution to avoid purple colors with tone mapping on dolby vision video files that don't carry a HDR10 fallback stream, but the guy from the post may have misunderstood

This problem is not related to the monitor : you didn't get the right version of MPV or didn't configure it correctly
On my side MPC-HC, MPC-BE and VLC render a purplish picture in dolby vision videos that don't have a HDR10/HLG fallback stream.
MPV works though, wether I use a dolby vision display or not (but HDR compatible in both cases).

1/ Create a %APPDATA%\mpv\mpv.conf file

# this is required for SVP to "catch" the mpv
input-ipc-server=mpvpipe
hwdec=nvdec-copy
#hwdec=auto-copy
hwdec-codecs=all
hr-seek-framedrop=no
vo=gpu-next
target-prim=bt.2020
target-trc=pq
gamma=5

2/ Enable HDR from windows 10/11 from windows settings System > Screen > HDR. Select the external screen (not the internal display) and enable HDR

3/ While having your external display plugged in : you have to set the graphic cards to output in 10 or 12 bits mode. See the capture below from nvidia control panel

4/ In SVP settings, set "Allow output in 10 bit color depth" set to always

Thanks for this info. I'll try it tonight!

I try playout on a none-HDR monitor using a freshly downloaded and installed MVP (mpv-x86_64-20220424-git-9d133eb)
I also installed latest VapourSynth + filter and I created your conf file but purple haze issue remains.

When I enable the RIFE engine the purple haze is gone but it also throws an error in the log:

Guess I messed things up with the manual installations of vapoursynth filters?

yes you did
