Can access from browser of real time images. V4L only supports a single open of any device. Motion http://motion.technolust.cx, supports Motion Detection and a loopback driver, so you can redirect that image to another '/dev/video', and open the loopback device with something like camstream. > > I have setup the webcam software come with xawtv which suit the above > requirement.

I'm told, and have experienced, the 878 only supports sending a single channel at a time. I currently have a 'piss-poor' driver based on Jeroen Vreeken's 'invert' example from the vloopback archive, that will loop through each channel and output it to it's own /dev/video. http://www.havokmon.com/stuff/multiout.c It works fairly well (I get 3 fps saved when motion is detected), except for a 'jump' that unfortunately is seen as motion.. I can let you know if I get that fixed.. If anyone else has a better solution, speak up! :) Rick > > Thanks in advance. > > > Best Regards, > > Almond Wong > Tel:91836223 > > > > _______________________________________________ > Video4linux-list mailing list > Video4linux-list@xxxxxxxxxx > https://listman.redhat.com/mailman/listinfo/video4linux-list -- Rick Romero IT Manager Valeo, Inc. ph 262.695-4841 fax 262-695-4850 rick@xxxxxxxxxxxx
