I'm having the same issues, I noticed an error with ffmpeg, that it can't be found. I've redownloaded ffmpeg and set it for the environment, placed it in and tried doing the --ffmpeg-location, but it's not seeing it. I wonder if that's the issue. I can play the videos in MPC but not in VLC for some reason as well.
