Minor Rusty blockage

[Mathieu Duponchelle]

That is surprising, this exact snippet of code should work, is it 
possible that you don't

actually use the latest version of gstreamer-rs? This function was added 
in July 2017, so

quite some time ago, but worth making sure.


It would also make sense to share the entire source code if that is 
possible, to

make it easier to reproduce and spot the problem :)
