gstreamer plugin example with openmp

[mirtexxan]

Hi,
I'm working on a presentation on Gstreamer and parallelism, and I'd like to show an example of use of OpenMp inside a simple Gstreamer plugin.
Do you have pointers to any useful example of this kind? If not, can you give some tips which can help me to write such example?
Any other idea on the topic of gstreamer and parallelism which can be useful for my presentation?

Thank you very much
