controling the camera with a hand-held device

I have a gp2x[1] gather dust

I am wondering if it is good enough to be used to control the elphel camera?


it has network supoort using tcp/ip over usb [2]
it has a web browser [3]
it has modified version of mplayer[4] and ffplay[5]


[1] GP2X - Wikipedia, the free encyclopedia
[2] UsbNet on Linux - wiki.gp2x.org
[3] Links Web Browser - wiki.gp2x.org
[4] MP2X - wiki.gp2x.org
[5] FFPlay - wiki.gp2x.org

basically I think it could work but it would require some sophisticated fiddling.

and the 200Mhz CPU will not be a real workhorse in terms of performance, even the beagleboard has 3 times the CPU power...

my only features I need are
* record/stop video
* take HDR photo
* apache file directory like gallery
* video playback via streaming transcoding on the camera

The only above point that really requires performance is video playback. Though if your main application is taking HDR photos and you just want a low resolution preview video for framing and focusing you could go with a lower resolution video stream (camera internal decimation/binning). Then I think this setup should work rather well.
Just be ready to spend some time to set everything up and some php skills / linux scripting would also be an advantage I guess.

a lot the features are locked down or are automated because of the panoramic nature of this project (two image sensors back to back with fisheye lens this setup is know as a spherecam see ryubinpanorama.com)
