Hi Philipp
Alas, I'm working on this as part of the show-and-tell aspect of a project we are developing, therefore I'm doing a lot of the general environment work more as a 'skunk-works' priority - i.e. out of office hours or 'in those spare moments'...
I am also using the Mistral EVM board and the SDK from Texas -- currently, getting gstreamer to build (cross compile) is the current roadblock.
Hopefully further progress will be made over the coming days.
Richard
