I think there is some sort of (broken?) HLS on gopro. I
remember that<br>
Thiago wanted to have a look eventually.<br>

I had access to a GoPro Hero3+ at some point and briefly looked at
how they did HLS streaming. It was nearly working with GStreamer
except that they had to use really small segments (under half a
second) and the playlist advertise the segments as being 1 second
long (limitations of the HLS version they use). At some point our
HLS demuxer loses sync and tries to reposition itself but the large
difference in the HLS advertised duration and the real one makes it
completely lost and playback<br>
derails.<br>
<br>
I have lost access to the GoPro Hero3+ I've been using and the Hero4
doesn't seem to provide HLS in the same way so I haven't managed to
find how to properly connect to its live preview but I haven't had
much time to dig into this yet.<br>
<br>
I also didn't check if there are other options aside HLS, there
might be.<br>
