Elphel cameras have two different APIs. The old ccam.cgi API and the Video API which is a superset of the AxisAPI. By default (after flashing), Elphel cameras (at least the 333 model) work in the ccam.cgi API mode, which means that all attempts to acces the images using the Video API will come back with a 500 Server Error.
To check wich API is currently active for your camera, use the "chapi.cgi" CGI script:
http://192.168.0.9/cgi-bin/admin/chapi.cgi?action=status
This will return and XML document such as:
<camera> <api>0</api> </camera>
meaning:
To change the API, use the action=setup&api=X parameters, e.g.:
http://192.168.0.9/cgi-bin/admin/chapi.cgi?action=setup&api=1
which will change the API even over reboots and return the changed configuration:
<camera> <api>1</api> </camera>
