Re: Controlling burst mode

Your requirements could be solved by using the --shell mode of gphoto2, 
allowing with some elaboration to replace the burst mode with a desired number 
of shots per second, depending on the camera/pc speed, using a custom script 
in a given programming language.

The shell mode is an advance mode to control the camera with gphoto (shots, 
live view, focus, ...), sending continuous commands to gphoto/camera instead 
of calling gphoto from the beggining each time (with 1-2s of initial 
overhead). Look at the mail list history to find more answers related to use it 
from console or from programming languages (mainly python and Java). I have 
tested successfuly myself one D5300 I borrowed in that mode, and I suppose 2 
individual shots/sec saved in SD would be possible with raspberry, but I 
recommend you to avoid using autofocus, focus should be fixed to ensure capture 
at a given rate.

Another option would be live view with --shell. As a reference, I've been able 
to achieve 2-3 fps in live view (images in PC, not SD) using an old Rikomagic 
RK802IV, which is faster than the Raspberry I think, so the Raspberry is 
probably not adequate for live view.

Tomas.
