The camera firmware repository is located here (contains a list of video/image capture modes that are recognized by the camera):

http://gitorious.org/omap3camera/

The specification for the 5 megapixel image sensor is located here (not very useful for encoding, I suppose, but it's a good reference nonetheless):

http://retiisi.dyndns.org/~sakke/foo...APL_090511.doc

I posed the question of video recording in 1280 x 720 to a developer here who did some work with the camera on the N900 (I'm not mentioning his user name specifically, as I'm not sure if he'll receive a multitude of messages posing the same question as a result), and the developer thought that it might be possible at ~20 frames/second or so.

As attila77 mentioned, the 3430 is not advertised as being capable of performing HD encoding, and Samsung very well may have adjusted the encoding bitrate in order to achieve the desired result with the Omnia HD. I happen to own an Omnia i8910 HD, and I also happen to have one of the first videos I recorded here on my hard drive at the moment. The video rate statistics for this 48-second clip are (as reported by Windows):

22 frames/second
8924 kbps data rate (video only)

I don't have an N900 video clip available at the moment, so I'm not sure how the data rate compares, but perhaps this information can be used as part of a feasibility assessment (granted, this is only a single clip)...

However, in this case we are dealing with a feature advertised everywhere in Nokia's PR about this phone, the supposed "dvd-quality" of the video camera. I don't know whether the solution is to open source the code or to push Nokia to resume work on this.

My suggestion would be that people keep voting the related bug:
https://bugs.maemo.org/show_bug.cgi?id=7062 adding useful technical comments when appropriate (it's a bug report, not a forum). Previous contributions to the bug report clearly indicated the developers' endorsing of the problem, until the WONTFIX.

At the end of the day, this is not even a matter of capturing video at 720p. This is a matter of capturing video properly, without stuttering, at whatever resolution the developers agree is feasible.

If others have more concrete suggestions, please share them.
