Created attachment 374032
example code in python
In a python demo program, I wish to demonstrate various interpolation methods
on low resolution video using menu commands and/or keypresses. This requires changing the interpolation method. For this I use calls like
self.videoscale.set_property("method", 'nearest-neighbour')
They seem to have not effect whatsoever. The property seems to be set properly
(can be read back using get_property) but is otherwise ignored.
This code was written a long time ago and I think it worked under an older version of gstreamer/pygi (not sure which one; this was many years ago)
Code is attached. Use the menus to change between methods.
