Video issue when compile with new ue4 version

Hi everyone,

I have uploaded an app on google play which contained a movie in .mp4 attached. It works very well until I had to upload a new version of it. I had to modify the libPNG because the google play security issuu. Since I did it the video doesn´t work, it makes sound but there is no image, the screen appears in black.

Any idea about how to fix it?

Regards!
