gopro hero3+ blank screen on hdmi[ New ]
Hello I have an old hero3+ camara.
I want to use it connected to a hdmi caputre in a pc.
it was working yesterday fine.
but sudenly when I try to visualize the hdmi signal I've got a blank screen. (and no option of playing video is enabled on the camera)
If I connect the camera to a display directly it works.
I thought that the capture might be faulty but I conected another camera to it and it works.
so I have no idea what is happening to the camera
does hero3 has some kind of drm protection?
the strange thing is that it was working yesterday.

Thanks for your anwer I carefully read those documents but the issue is still there.
Something is really weird And I can not figure out where.
I pluged the gopro (which by the way is a black edition not a silver) into seveeral screens and the hdmi output is working fine.
But aswell I thorw almost anything that has an hdmi output to the campture and i worked with everything.
the most weird thing is that today I was playing desperately
changed resolution on the camera conecting the calble power or power off.
usb on usb off.
and suddenly the image came back and in the same way it went off.
So I think thre is some kind of sync issue between the two devices.
not sure how the go pro negotiates the ouput format.
