Topic: Dolby Vision Support

I used the JRiver player combined with SVP and AVISynth. JRiver recently added "limited Dolby Vision processing on Profile 7 video streams (similar to a Profile 8.1 stream), including the new per-scene brightness data".

Unfortunately it doesn't appear that using SVP with AVISynth passes through any DV data. I got a reply from one of the JRiver developers:

"I had a look at the Avisynth Filter they recommend to use, and while it processes some basic HDR metadata, I see no trace of supporting DoVi metadata, neither the old or the new version with the extension data. Someone tried to add support some time ago but it never got anywhere. Either way, the filter would need to forward the metadata from LAV Video to JRVR, thats the only way it can cooperate with DoVi."

Hoping this could be added in the future. Thanks!

Re: Dolby Vision Support

AVSF bundled with SVP actually passses DoVi data (those commits ”Someone tried to add support some time ago but it never got anywhere”), and it definitely works with MPC Video Renderer.

Re: Dolby Vision Support

I posted your response to their beta forum (I can't link directly to it since it is beta and they just added DV support). This is the response I got:

The metadata was updated in LAV 0.80 to include DoVi extensions, so they would need to cover that change, if they don't already.

Any hope of one day being able to use RIFE Interpolation while maintaining Dolby Vision playback on Windows?

what exactly doesn't work?
mpc-hc/be + vapoursynth filter + mpcVR

Basically, whenever I try playing back a DV file with either MPC-HC or MPV (both correctly configured for SVP and RIFE use, in both MPCVR and MadVR), whenever I try to play a DV video in fullscreen my monitor falls back to HDR10.
However, if I try playing back a DV file in the Windows native app called Films & TV, it successfully plays back the DV video, making full use of DV metadata.

there're many options to configure in mpcVR settings

But none of them actually mean full passthrough of DV?
