So i've used this combo many time before. I usually take my gopro out of the zenmuse after flight as I use it for other things. On this flight, the gopro was fully charged before install. turned on the phantom and let it warm up. Turned gopro on. FPV check was good. video and iOSD both streaming fine. But when i push 'record' on the gopro and took off, after the picture started to flicker every couple of seconds and I would loose video for about half a second but not the iOSD. This kept happening for about 30 seconds then the video stopped completely. After landing the gopro was off and would not turn on again. When i got home I took the gopro out of the zenmuse and it turned on and would record just fine. tried again in the zenmuse with the P2 on the ground. Video stream is fine if the gopro is not recording but as soon as you hit erecord, the video stream stops ever couple of seconds for a half second. The timer on the gopro also freezes in time with the video stream freezing and timer only updates every couple of seconds. When it gets to about 30 seconds the gopro freezes completely and turns off. Memory card has worked fine for months so dont think thats suddenly become an issue. Also tried the gopro on photo mode too. It streams fine when not taking a photo but every ten seconds when it snaps a jpg, the video stream goes blank again. Anyone else had or heard of similar issues?
