Gstreamer is not working (Windows) (Nirbheek Chauhan)

Mon Jun 22 18:45:49 UTC 2020

There is no need to delete the mingw binaries.  (Your installation probably
did that already.)

You just need to delete the plugin cache whenever you switch from one
version to another, as described here:
http://gstreamer-devel.966125.n4.nabble.com/msvc-build-can-t-find-elements-in-playback-plugin-td4691649.html#a4691668

Hopefully that will just work.
