Description Edward Hervey 2016-10-09 13:22:42 UTC 
gopro4 can send a live stream over wifi.

It's mpeg-ts over udp, but it contains 12 extra bytes at the beginning of each udp packet. It *looks* like a rtp header ... but it doesn't seem 100% right.

(first mpeg-ts packet is at "47 10...")
Comment 2 Nicolas Dufresne (ndufresne) 2016-10-09 13:50:00 UTC 
According to few forums, it's compatible with VLC / FFMPEG of mpeg-ts over UDP. One could check the code there.
Comment 3 Nicolas Dufresne (ndufresne) 2016-10-09 13:50:46 UTC 
(or it works by accident because vlc just ignore those bytes ?)
Comment 4 Edward Hervey 2018-05-04 12:40:43 UTC 
If someone has a gopro and can provide a patch to support them, they're welcome to re-open this bug.
