Can't play video in Samsung Smart tv (tizen app)

I am making a Samsung Smart TV app with Tizen web app. I want to play videos in my app. I’ve tried different steps. Writing the code to play video with HTML5 video tag. Upon not playing, I’ve tried this video sample and this is also not playing video.

I am doing this on real target device.

All things are same. I’ve not changed anything. The only change, I have done is on this Some error happened, I’ve just added JSON.stringify(e) to see the error, because otherwise it was giving me object. Here are the logs screenshot which I am getting on this:

If you know something please let me know what I am missing. Thanks in advance!
