So I guess then you would be putting the name into your gst_parse_launch 
string? Or are you iterating over all elements in a pipe and giving them 
names? Also when you use bins like encodebin or decodebin getting the 
child seems harder to me, as does setting some of the settings... Just 
my opinion though. I've only been using gstreamer for a year or two.
