I built latest Main on Windows, but it doesn't start. I always get the following DEBUG-ASSERT:

QMimeType("video/mp4") "mp4"
DEBUG ASSERT: "s_fileTypeByMimeType.constFind(mimeType) == s_fileTypeByMimeType.constEnd()" in function bool __cdecl SoundSourceProxy::registerProviders(void) at ..\..\src\sources\soundsourceproxy.cpp:247

This happens because Mime type video/mp4 is registered twice:
QMimeType("video/mp4") "m4v"
QMimeType("video/mp4") "mp4"

I will provide a fix.
