fakesink and CPU load

[Cyril Baletaud]

Thanks,

No, i don't check out camerabin, i will do.
I'm working on a rtp bin, to transform GiGE vision heavy load stream to a
lighter one. This is why I need to enable or disable a bin, without
stopping the pipeline.

This model is inspired by
https://coaxion.net/blog/2014/01/gstreamer-dynamic-pipelines/
The template works fine, but I am listening to your best tips.

Cordialement
