Hi jnordberg -- this is very exciting. I've got a question that will likely seem silly but it's been a long time since I tried to mess with the Yi -- do I need to install something on the camera itself other than those few lines to autoexec.ash? And what is the form of a <camera_path>?

My Yi arrived and I'm in via telnet. Poked around a bit to see if I could find ambsh.

Some more interesting Ambarella info: https://www.defcon.org/images/defcon-21/dc-21-presentations/Manning-Lanier/DEFCON-21-Manning-Lanier-GoPro-or-GTFO-Updated.pdf Maybe it's not useful for me to post links to every bit of Ambarella info I find in here. I'm just hoping that somewhere in all...

Has anyone yet managed or tried to do the following after telnetting in to the Yi: Manually set the shutter speed Manually set the aperture Manually set the ISO/gain Manually set the white balance Trigger the camera to start recording I read through the list of autoexec commands that were...
