VapourSynth R82

VapourSynth R82 makes vspipe’s Matroska output playable in mpv and sets track properties from the first frame; it also avoids downloading GPU-resident frames when there is no output and fixes slow GPU-filter performance on Nvidia cards with Resizable BAR. VapourSynth is an open-source video processing framework for scripting and chaining filters to restore, resize, and convert video, used in video editing and encoding workflows.
