+        av_log(s, AV_LOG_WARNING, "Changing video frame
properties on the fly is not supported by all filters.\n");\
In which situations is this new warning shown?
e.g.
       -reinit_filter 0 -i ChangingResolutions.mp4 -vf somefilter  ...
Is it only shown if the filter does not support re-initialization?

No. As the existing msgs indicate, it is always printed when _some_ frame properties have changed. The new addition allows the user to discover which properties those are, with timestamp. They can then choose to continue, allow reinit or partition the input (if viable) as appropriate.
