I use CHDK (alpha) on my A4000IS. I want to use the camera for aerial photography, so I need permanent video out for the downlink. I finished making a combined remote shutter/AV out cable yesterday, but when I plugged it into the 11 pin port of the A4000 - nothing happened.
I resoldered the cable two times, checked everything again and again. I even shorted pins 6 & 7 and 6 & 11 on a spre plug, but even the screen did not turn off. Then, quite accidently, I realised that this is only in shooting mode. When switching the camera to playback mode, video out works with my cable.
Each and every camera I own, no matter if it is some years old or brand new, expensive or really cheap, every brand has a live view at its video output in shooting mode. Am I missing a setting, or is this feature not available on the A4000IS? Can CHDK help with activating live view at the av port in shooting mode? Wich PowerShot cameras are known to have a working live view via av out i shooting mode?
