poster attribute in html5 video tag work bad on android

everybody.

I Have a problem with the poster attribute en html5 video tag. I'm doing an app with ionic Framework and I need show some videos inside, the videos extension are m3u8. When I play the video just get sound and the poster attribute doesn't hide, but if I pause and play the poster attribute again,it hides and the video works perfectly.It is like the video is behind the poster attribute and when I pause and play disappears.

my code it is:

I momently solved this using a settimeout doing an automatic pause and play function but is not the solution that i want.

code:

setTimeout(function(){
    document.getElementById("myVideo").pause();
    console.log('paused');
    document.getElementById("myVideo").play();
    console.log('playing');
}, 6000);
