Video doesn't display on android 4.18.3

Why my video doesnt display in my game on an android platform ? There is a blue or black screen instead of my video. This is the 18th version of UE4. On the 16th version of UE4 has displayed everything.
But on the PC, everything is displayed on both versions 4.16 and 4.18

I have used this documentation ( ) but it doesn’t work either.
