Problem with using gst-launch (with avidemux and videoconvert)

[Ian Davidson]

Thanks Tim,

I noticed that you recommended camerabin 'not using gst-launch' but I 
tried it anyway to see what happened.  I noticed that I got what I 
assume to be a 'viewfinder' - which is good.  I also noticed that I did 
not get any still pictures - presumably that is why you said I should 
use an application.

I assume that I need to send a signal to camerabin to tell it when to 
take the picture (a shutter release) - but looking at the output from 
gst-inspect I did not notice how I should do that.

I noticed that there is a property 'video-filter' which says what is 
going to  handle the picture - I assume that I need to create a pipeline 
which includes 1) camerabin and 2) pngenc (for example) and 3) 
filesink.  I will then need to link pngenc to filesink, but presumably 
camerabin will link itself once it knows what it should link to?
