I am trying to play video in Tizen web app. I use sample code:

var video = document.createElement("video");
video.src = "video/0.mp4";
video.controls = false;
video.muted = true;
video.autoplay = true;
video.loop = true;
document.body.appendChild(video);

But I get a strange error from Emulator:

After restart of app I don't see this error. But video don't played - I only see black screen. No errors on debug console. currentTime is changing (like system think that video is playing). If I set video.muted = false I can heard the video sounds.

I can't test on real device. What It can be? I have trying differents video formats - result the same. On Tizen Simulator all working good. On Tizen Emulator - not working...
