Spent the nice and sunny weekend ... sick in bed.
Some gphoto work done in the last days ... I implemented the Nikon SDRAM capture mode. Capturing to SDRAM of the camera instead to the card has the obvious advantage that you safe the save-to-card / reload-from-card cycle if you just use the camera in a webcam like mode.
The capture-download-delete mode of gphoto2 now can capture and download around one 5megapixel image every 5 seconds from the P2.
I have ported my previous Canon SDRAM capture integration to use the same methods. Since my IXUS 2 uses USB 1, it is a bit slower in turning around images, but at least it does now in a consistent way.
On the PTP/IP front ... I can now download images over WLAN. Things missing are: Eventhandling, Data write, and lots of cleanups. Also zeroconf discovery is still missing.
