LoadAllPlugins

std.LoadAllPlugins(string path)

Loads all native VapourSynth plugins found in the specified path. Plugins that fail to load are silently skipped.

Beware of Python’s escape character, this will fail:

LoadPlugin(path='c:\plugins')

Correct ways:

LoadPlugin(path='c:/plugins')
LoadPlugin(path=r'c:\plugins')
LoadPlugin(path='c:\\plugins\\')
