Could you use the existing libmediactl format? The parser exists as well.
As a matter of fact, I have a few patches to make it easier to user in a
library.
libmediactl appears to be located under utils/media-ctl. Perhaps it's be
better placed under lib. Cc Laurent.

I didn't know you were working on this.
I have a small library which does essentially the same. The implementation
is incomplete, that's why I hadn't posted it to the list. We could perhaps
discuss this a little bit tomorrow. When would you be available, in case you
are?
What would you think of using a little bit more condensed format for this,
similar to that of libmediactl?
