ffmpeg/ffplay works OK.

I tried FFMS from "ffms2_r1327+119-avs+vsp.7z" got: [avisynth @ 05807b60] FFVideoSource: No suitable output format found (FFMS2.avsi, line 36)

?

Who built that one? Doesn't look like an official build to me

It's the C plugin. The revision number gives it away (both that it has one and how the number is calculated/formatted).

A) https://github.com/qyot27/ffms2_cplugin/issues is where issues with the C plugin should go now. I hadn't bothered enabling it until now because usually issues are just posted to the Doom9 thread.

B) That's expected behavior when trying to open high bit depth content with the C plugin in AviSynth 2.6 - the C plugin will not do automatic downsampling to 8-bit. Use the colorspace= parameter to force convert it at load, or use AviSynth+ to preserve the high bit depth and/or dither it down with ConvertBits() or avsresize() or whatever.
