Currently, I am building mpv via the media-autobuild-suite. It works quite well for most purposes, but I cannot seem to get it to communicate with SVP properly.
So the following command *works*
& 'C:\Program Files (x86)\SVP 4\mpv64\mpv.exe' --hwdec=auto-copy --input-ipc-server=mpvpipe --hwdec-codecs=all --vo=gpu '.\1x01 - A Stitch in Time.mkv'
The following command does not:
mpv --hwdec=auto-copy --input-ipc-server=mpvpipe --hwdec-codecs=all --vo=gpu '.\1x01 - A Stitch in Time.mkv'
The error the above command gives is as follows:
[vapoursynth] Script evaluation failed:
[vapoursynth] Python exception: SVSmoothFps: unable to init GPU-based renderer - code 65536

Disabling filter vapoursynth.00 because it has failed.
My guess is that this has something to do with opencl or something? Would anyone happen to know what I need to do with my mpv building process in order to fix this? What config options I'd need to toss in there, etc.
---edit:
... I post that and, as happens, I immediately find the answer myself.
Turns out, I had a copy of OpenCL.dll in my mpv.exe directory that was out of date. I deleted that, forcing it to rely on the version in system32, and it worked fine.
So uhh, if anyone has that issue, do that I guess.
