Hi Jens, Concerning gstreamer support check my blog post on using gstreamer with Elphel cameras: http://blogs.elphel.com/2009/11/interfacing-elphel-cameras-with-gstreamer-opencv-opengl-and-python-get-profit-of-dsp-or-gpu-based-optimisation-control-camera-settings-from-python-application-or-human-interface-device-hid/
It show also how to manage the latency. Internal latency from sensor to network is < 2 frames. astreamer is the streamer on the camera, yes. to download RAW image you can use this script : http://elphel.cvs.sourceforge.net/viewvc/elphel/elphel353-8.0/packages/web/353/php_top/raw.php?revision=1.2&view=markup Best regards, Alexandre On Mon, Jun 14, 2010 at 7:47 AM, Jens Bürger <jens.buer...@cs.tu-dortmund.de > wrote: > Hi, > > our student group is constantly discovering the various areas of code and > structure of the cam, so we come to additional questions from time to time. > > At the moment, we have the following ones: > > What is the difference between the elphel_wait_frame_abs and > elphel_wait_frame functions? > As I unterstood it, elphel_wait_frame 'syncs' to completed, compressed > images, but to what does the _abs-function 'sync'?
