By the way, I think you mean "composite video", not component video.

Someone correct me if I'm wrong, but rotation is not a smartrender-able transformation; loss of quality will be involved.

If possible, it's best to get the camera to do it.

Going to make a great taxicam or security cam. Can also connect to DVR with the video out to record continuously at 720 x 480 resolution on it and then have the board recording contentiously in HD so when something does happen, you have the HD footage.
Continuous recording is a dicey feature which needs a significant amount of thought put into it. In "dash cam" mode, as soon as the thing is powered up, it should start recording. The button would then control "event capture". If you just saw something interesting, then you would press the button, and it would save the video to a save directory that won't be auto-deleted. So say the thing breaks the videos up into 5-minute intervals -- when the button is pressed, the previous 5 minute interval is saved off, the current video is immediately saved, and the next 5 minute interval is saved. You also need to gracefully handle the poweroff event.

Date/time stamp is also helpful, at the very least on the files. Does this have an RTC?

The intervalometer is nice for RC usage -- say I want to just throw the thing on an RC plane and take full 9MP photos every 2 seconds. No extra timer board, no servo shutter control, just plug and go.

There are some other programming modes that I could think of that would be useful for me; more along the lines of security camera usage. How’s the standby power drain on this thing? Can the live-preview circuitry be turned off to save power? And how’s the low-light sensitivity? Is the IR filter removable?

My real point was that, if possible, the thing should be user-programmable. Right now you are sort of mimicking the Gopro’s form factor as well as its lack of features, which is probably a bad place to be.

Just some stuff for you to think about.

Logic and reason are anathema to him; but this does not deter him from prattling on.
He is the most interesting player in the world.
