FFmpeg and mpv built with static VapourSynth/Python, 2019-10-10

VapourSynth: git-bae5d1a
Python: 3.7.4

The incompatibility is most likely tied to the version of Python, but VS itself probably incurs *some* of the restriction too (it matters which version of Python the VS .dlls were built against, just as much as it matters which one is linked into FFmpeg). I still have Python 3.7.3 and the official release build of R47 installed system-wide, but built FFmpeg with Python 3.7.4 and VapourSynth's current git HEAD. It worked just fine. It seems to be okay as long as the Python and VapourSynth linked into FFmpeg are newer than the ones on the system, but the inverse situation will almost certainly fail.

As before, both VapourSynth demuxers are present. The upstream demuxer is vapoursynth, the rawvideo demuxer patch provides vapoursynth_alt.
