All cameras must run for thumbnails. I have found the N:1 selector element. That seems like the solution.

I mean, are you doing background video recording with them? If not, you can simply change the input camera with a timeout trigger. pause the pipeline change the attribute source of v4l2src element restart the pipeline start timeout again Regards, <div><div></div><div class="h5"> On Tue, Aug 17, 2010 at 6:32 PM, Bert Douglas <<a href="mailto:bertd@tplogic.com">bertd@tplogic.com</a>> wrote: > Hi All, > > Is there a plug-in to do an output mux? > > I have several cameras.
