RPI3+ Video is not working

[BKR]

Hello,

I installed Rasbian Stretch and Kivy 1.11.0 on my RPI3+. My application work properly just videos are not playing. Rasbian and gstreamer are up to date. Do you have any idea? 

Logs like below;

[INFO   ] [MTD         ] </dev/input/event0> rotation set to 0

[WARNING] [Image       ] Unable to load image </home/sysop/data/images/cityCC0.mpg>
