Missing Animate video for export AIR for Androïd

Hello,

I made an AIR for Android application via the latest version of Animate CC. I added animations, images, sounds and a video.

Once my APK file is installed on my tablet, everything works except my video, and I don’t understand why...

It is exported in H264 and I tested all formats but nothing is shown! However, when I use the "test" function on my computer before publishing, it works...

I’ve done a lot of research and tested the application on other Android devices, but it still doesn’t show up...

Can anyone help me please ?

Thank you in advance for your help!
