Topic: "No active playback" when using MPV

Hello!

I'm using the latest version of SVP 4 PRO on Win10 and wanted to give MPV a shot, but it doesn't seem to detect playback.
There is also no OSD and it's pretty obvious that SVP is not functioning.
I also tried "Open file via MPV", but the result is the same.
Changing admin privileges didn't help either.
Any help would be much appreciated.

Re: "No active playback" when using MPV

SVP's and mpv's log (via "--log-file=\some\path") should help

Alright, I finally got around to testing this again and the SVP log does indeed throw up a number of error messages:

Does anyone with more knowledge have any idea what's going on?

I will create an MPV log next and post here if I see anything interesting.

Re: "No active playback" when using MPV

Thanks for the Link!

I was afraid of this... Nvidia drivers are so notoriously unstable that I always avoid touching them for as long as possible. Anyways, I'll give it a shot and reinstall them and report back.
