Clean and migrate libav-presets repo in tuttleofx organisation

[mfe]

Cf https://github.com/MarcAntoine-Arnaud/libav-presets

[cchampet]

libav presets are handled in the avtranscoder project (which is currently a submodule of Tuttle)
Cf https://github.com/mikrosimage/avTranscoder/tree/develop/ressource

Is it correctly deployed with "make install"?
Is it directly used with relative paths?

[cchampet]

Yes the presets are deployed when "make install", in tuttle/share/ressource
But to use them, we need to set AVPROFILES environment variable.
I will create an issue in avtranscoder repository to set path by default.

Done here: mikrosimage/avTranscoder#91

Maybe we could also add an ofx parameter in the plugin to see and modify the preset path.

[cchampet]

Will this work even if the preset path is an environment variable ?
