html5 rtmp solution

hi i have a question theres any solution to play live streaming via mobile i mean when people get to my website example they can see live streaming i know html5 doesnt supports rtmp but i saw some websites like in my mobile and i can play the live streaming without issues is like the player have some switch that doesnt ask me to download any file any mp4, instead i can see the live streaming in mobile without issues in the website not in the video player of mobile i dont know if they are using something else other than rtmp. I you guys can give me an advice to accomplish this, ill appreciate it. Thank you very much.
