Support for Livestream.com livestreams (w/ howto) + HLS scanning suggestion

[rowrawer]

Hi,

I've been told this would be the most efficient way of reaching the developers in regards of additional functionality. I would love to see more livestreaming sites added as this would save lots of headaches in the future.
One of the simpler ones to implement is Livestream.com. All you need to do is search the website's source for m3u8_url and then plug it into ffmpeg.
So for example if I'd want to capture this random thing: http://new.livestream.com/popsugar/live here's what I'd do.

I check the source and find http://api.new.livestream.com/broadcasts/39287043.m3u8?dw=100

So I plug it into ffmpeg:
ffmpeg -i "http://api.new.livestream.com/broadcasts/39287043.m3u8?dw=100" -c copy output.mkv

And that's basically it. Hope this gets implemented soon.

One more thing: when using the generic extractor thing, would it be possible to implement a cycle of scanning the page for m3u8 playlists with the user agent of an iPhone/iPad? Many sites offer straightforward m3u8 playlists that you can input into ffmpeg if the user agent is set to a mobile Apple device.
