Comment (by dan@…):

 There is no demand for them to be co-installable. In fact, if both
 libmltqt4 and libmltqt5 are in the same folder from which MLT is loading
 plugins, then it is going to fail because Qt does not allow mixing
 libraries from different major versions in the same process. Due to how
 MLT loads and registers plugins, merely the existence of both will cause
 them both to be loaded at startup; it is not on-demand by the application
 or composition.
