I'm really sorry if this subject has been asked before but I cannot find the answer.
If I connect my cheap china cam (PAL) to the MinimOSD (v.1.1) everything is fine, the signal is overlayed by the data, but if I do the same with my GoPro Hero2's analog signal only the video is transmitted. No overlay at all. If I remove my video source the overlay appears on the gray background.
Now i was able to check your video.
So reset does not works? Hmmm.....
Don't use the middle wire from gopro. (+ wire)
That could case this. Only the white and black should go to minimosd.
Don't cut it yet, just pull it out from the plug. ;)
Hope it solves it.
i think Gábor is at the right way.
Like i saw on your Vid, your MinimOSD is separately powered by 12 V
You connect (i think so) a 12 V cheap chinese Camera ---> it works including Overlay
You connect a 3.7 V GoPro to the 12V powered MinimOSD and create a V conflict ---> only Vid, no Overlay
The solution is correct: cut the + cable of GoPro and connect only Ground and Signal to the MinimOSD.
I also work with a 7.2V Panasonic and a 12 V onboardcamera and switch between the 2 Cameras-
NO PROBLEM with the Overlay.
I'll hope Gábor's tip + my explanation will help you.
happy flying Rolf
It sounds like a good explanation, I'll try it later to day.
I'm glad it does now! ;)
Are you using the stock code in your MinimOsd?

I am also very happy, that it works now.

I too was having a very similar issue, but with my FPV camera (decent readymadeRC RMRC-600XV.
Found by putting a momentary push-to-break button in the +12v line between the MinimOSD and the camera, I only had to tap it a few times, and it loads up. Not a fix as such, but certainly a work around that I'm happy with.
Thanks to Michael for posting up this issue, as well as Rolf and Gabor for helping to resolve it. Legends!
See it briefly in my video below:
I simply disconnected the voltage wire from the OSD to the GoPro.
I just checked back to provide a solution and saw your post (could've saved me a bit of time :)
Eventually did the same thing and problem solved for both my GoPro and Flir camera.
I also did some other things and not sure if it had an effect, I was getting desperate (and like I said, I should've checked back for you reply) - I tied the solder jumpers together to power from APM, also soldered the PAL jumper, set my GoPro to PAL and disconnected the voltage leads, but kept signal (obviously) and Ground in tact.
Now for some thermal night flying!
