[FFmpeg-user] HTML5 live streaming

Tue Apr 23 04:19:45 CEST 2013

Hi Jonathan,

This is awesome! It worked! :-)

so my next step... how do I do adaptive bitrate? For example, I want to
have a stream for iPad, a stream for iPhone, Android...

Another question... does m3u8 work for a desktop browser? I do I need an
embedded player like JWPlayer for desktop?

Thanks so much!
Ricardo
