I have a media player and create the corresponding media texture.
Firstly I set media player url to sv2.wmv.
Then I change url to sv.wmv.
Finally, I click play button and editor crash.
ps: I firstly wished to change media texture at runtime. I implemented this logic in blueprint and engine crashed. Then I tried the similar operations in editor and find the crash problem always exists. I think maybe the problem is related with texture size.
