		+	*Output of the videos go into your 'video roll' area, and can be offloaded via USB.
		+	*You can edit videos directly on the device for start/stop point (total length)
		+	*If you want you can connect USB to offload the video but note also - :
		+	*You can email videos immediately from anywhere directly from the phone/EVDO - no need to connect to computer first.
		+	*Patches available to extend the allowed email length (30 seconds.)
		+	*Same as anything else you can do with a stored video (upload to facebook, etc.)

This seems to require recompiling camsrc with palm's 'capabilities template' removed or adjusted(palm offers both the base v4l2 drivers as well as their patch to compile the camsrc plugin on their opensource website). There's also a comment in palmInitMedia.js that the driver only supports up to 480x320, but v4l2 is documented to handle higher resolutions. Will also requre installing another video encoder. --[[User:Prenos|Prenos]] 20:10, 27 August 2009 (UTC) '''UPDATE''': this seems to be infeasble due to memory limitations, tons of segfaults and things. might have to do some serious buffering and framerate adjustments to get this to work.
