Video streaming

After looking for answers in other topics and not finding an answer, I am encouraged to open this question.
I am building a simple application with a link to a live broadcast of our TV channel. The link is http://link.m3u8 2. He programmed 2 types of buttons:
1.Button 1
ActivityStarter1- Url of m3u8 data-link
ActivityStarter1-Start Activity

2.Button 2
VisorWeb1-go to Url-link m3u8

Button 1 activates the phone's browser, and the video looks good, but you exit the application. You can even activate full screen
Button 2 activates the video in VisorWeb, but you cannot activate full screen, and, worst of all, the video gets stuck.
I don't know where to go anymore. Thanks for the help.
