Given a video node, it can find possible pipelines to the image sources with common formats. I.e. the ccdc -> rsz path is not available for raw cameras. C (especially without helper libraries) wasn't particularly suitable for the task, the data structures I had didn't end up too nice. What would also be necessary is to associate library or application specific data to entities, this could be as simple as key-value pairs with both key and value being pointers. > > Last thing..

Unfortunately the et8ek8 does not conform to a standard such as SMIA. :-( I'm not sure the datasheet provides enough information to come up with new mode definitions. Perhaps with some experimentation it could be possible. There are a few additional embedded documents in it, those are worth checking out. LibreOffice can open them AFAIR. -- Regards, Sakari Ailus e-mail: sakari.ailus@iki.fi XMPP: sailus@retiisi.org.uk
