Displaying a Youtube video within an AIR Android app

Hello;

I'm trying to display a Youtube video within an AIR Android app.

Usually, I call the Youtube API player like this (barebones only):

loader.load(new URLRequest("http://www.youtube.com/apiplayer?version=3"));

player = loader.content;

player.loadVideoById("12345678901",0);

I don't know why, but this method doesn't work anymore.

Here's what happens on the ANDROID device (I compiled using AIR v18):

The video seems to be buffering for a few seconds, then the movieClip holding the API player becomes transparent, no video is displayed.

The sound of the video is playing though.

Meanwhile, on the ADL, the video shows up as it should.

I'm using Android 5, the Youtube Video is on public status, and I already re-tried after uninstalling the Android app (but does it clear the cache?).

Does anybody has a clue on what's going on?

Thanks a lot!
