Brian, Current software (8.x) does not require call to elphel_program_sensor () - that function was removed. In the 8.x software it is not required to wait for the parameters to be applied and the acquisition queue is not reset when parameters are changed. That causes some variable (dependent on the parameter type) latency between setting of parameter(s) and receiving the image that was acquired with those new parameters . If you really need to wait for that you may use approach in the following example:
http://elphel.cvs.sourceforge.net/viewvc/elphel/elphel353-8.0/packages/web/353/php_top/snapfull.php?view=markup That program reads and saves current parameters, then applies new ones, shedules parametes to be restored to original ones, waits for the image with the new parameters to appear in the video buffer and redirects the http request to the imgsrv server (port 8080). It is designed to acquire a full resolution image causing shortest possible interruption to video streaming at lower resolution). Andrey
