Hello, I am new here and I am not very knowledgeable about this stuff but I enjoy learning. Currently I am trying to play DV video and I am having the green red hue problem. What I am seeking to know is how to set up mpv player. I already have ffmpeg installed but am unclear about libplacebo. I am using Windows 10. I am having trouble understanding "vo=gpu-next" as to what it is and how to 'enter' it. Sorry if this is something that has been answered and I am missing it or is being asked in the wrong place. I am not the swiftest cat with forums. I can follow instructions but I am a noob with a lot of this. Thanks anyone who can help.

Using prompt go inside the folder where the mpv.exe is and then go with: mpv.exe --vo=gpu-next C:\path\to\video\filename.ext

Yeah, indeed, this is supported now with --vo=gpu-next and sufficiently recent ffmpeg/libplacebo (ffmpeg 5.0, libplacebo 4.192.0).

Can ffmpeg convert DV to HDR/SDR now?

Yes, see https://ffmpeg.org/ffmpeg-filters.html#Examples-90

It is done automatically by the vf_libplacebo filter when DV metadata is present.

How would one be able to use it within macOS then?

No gpu-next in Mac https://github.com/mpv-player/mpv/issues/11308 https://github.com/mpv-player/mpv/issues/10978 https://github.com/mpv-player/mpv/issues/11301

OK, so no dolby vision playback on macOS possible at the moment?

I tried to play the testfile as mentioned in the original post, but with the same result.

how can I play hdr files on macOS Apple Silicon, I've compiled mpv myself, it does recognise the file as hdr and shows proper colors to use 2020-ncl*, but it just doesnt look as bright/colorful(maybe), like the same video played over safari, it's a lg oled video https://youtu.be/njX2bu-_Vw4

I have the following versions installed:

ffmpeg-6.0_1,1                 Realtime audio/video encoder/converter and streaming server
ffmpeg4-4.4.4_2                Realtime audio/video encoder/converter and streaming server (legacy 4.* series)
libplacebo-6.292.0             Reusable library for GPU-accelerated video/image rendering
mpv-0.35.1_5,1                 Free and open-source general-purpose video player
nvidia-driver-535.54.03        NVidia graphics card binary drivers for hardware OpenGL rendering

And I have set vo=gpu-next, but I still get funky colours. Is there anything else I need to do?

edit: it's weird how it affects certain parts of the image and not others (depends on scene).

but gpu-next certanly looks better then for example XV:
