Use IR remote to start/stop video recording
Someone told me there is an IR code to start/stop video record for NEX camera:
I tested it on my PSP and it works!
BTW, only the PSP-1000 has the IR port.
And you have to use custom PSP firmware and install an free IRShell software to use as the IR remote controller. Here is the screen shot of my Sony NEX-5 Remote Controller for PSP.
It's not quite useful, just for fun. If you have a PSP, you could download the remote control setting file here:
I'll add the "Video" button to my open source Sony camera IR shutter and time-lapse controller later next month.
