Globosat play: How can I download live streaming from it?

[gooz]

Hello guys. I've already tried several ways to capture this streaming but didin't succeed.

The url is http://globosatplay.globo.com/canal-brasil/ao-vivo/

I would really really appreciate any help on it. This streaming shows several rare brazilian movies and capture them would be amazing.

EDIT: The best I can get is using ffmpeg with the m3u8 path but it only downloads about 5min of video. It seems there is a playlists flow separating the pieces.
