Add Strawberry 0.5.2 for Stretch, which is a fork of Clementine.
In the separate ffmpeg4 repository, updated ffmpeg to 4.1.1, and added zimg and vapoursynth so I could rebuild mpv-0.29.1 with vapoursynth support. This then allows you to use mpv and mpc-qt with the Smooth Video Project--at a the cost of some CPU cycles for the realtime frame interpolation. You'll need to have the upgraded mpv for the mpc-qt GUI to work with SVP, too. https://www.svp-team.com/wiki/Main_Page
