Is this correct, having a problem getting vapoursynth to work this way?

Is this cmd correct? Something wrong with vapoursynth cmd. Please suggest a fix thanks in advance.

ffmpeg32 -re -i 1.avs -fps_mode passthrough -f yuv4mpegpipe - | "C:\Users\RW\Palemoon Downloads\stuff\vapoursynth-portable3\mpv.com" --profile=low-latency --framedrop=no --vo=direct3d --vf=vapoursynth="C:\Users\RW\Palemoon Downloads\stuff\smoother\mvtools.vpy:buffered-frames=2:concurrent-frames=8" -

Error parsing option vf (option parameter could not be parsed)

The problem is the : in C:\.... Filter options are separated by :, so mpv reads your path as C plus a bunch of broken options. The double quotes you used don't help because cmd strips them before mpv sees them, and they also wrapped buffered-frames/concurrent-frames into the path.

Name the file option and quote just the path with mpv's [...] quoting:

--vf=vapoursynth=file=[C:\Users\RW\Palemoon Downloads\stuff\smoother\mvtools.vpy]:buffered-frames=2:concurrent-frames=8

Full command:

ffmpeg32 -re -i 1.avs -fps_mode passthrough -f yuv4mpegpipe - | "C:\Users\RW\Palemoon Downloads\stuff\vapoursynth-portable3\mpv.com" --profile=low-latency --framedrop=no --vo=direct3d "--vf=vapoursynth=file=[C:\Users\RW\Palemoon Downloads\stuff\smoother\mvtools.vpy]:buffered-frames=2:concurrent-frames=8" -

The outer "..." keeps the argument together for cmd (the path has a space), and the [...] is what mpv's sub-option parser uses. See "Escaping spaces and other special characters" in the mpv manual. If you'd rather avoid quoting entirely, moving mvtools.vpy to a path without spaces and using file=[C:\vs\mvtools.vpy] works too.

I typed solution twice on IRC, but I think no one read IRC...

Thanks, that works.

Sorry, I didn't recheck IRC, and I only waited awhile for someone to answer.
