Raw data access

Hi list!

Is there already some possibility in phonon to access the images of a
video-stream (e.g. of a direct-show device)? Does the VideoWidget for
example get access to the actual images (the code of videowidget.cpp
is quite small and I coulnd't find anything in this direction)? Or
does it intermediate only between the source and the drawing functions
of the actual backend?

thx a lot!
-Thomas

Yea the Phonon code itself doesn't have access to it. There was a
proposal for an API to allow screenshots of video (actually I forget
if this went in or not?).

The API would be implemented by the backend, which does have access to
everything.

Ian is right.

The backend has access to video data. We even have our own video renderer
(have a look at videorenderersoft.cpp in the DirectShow backend).
There is no interface for that in the frontend so no application can access
it.

As for the screenshot, we're considering adding it at some point but it's
not yet done.

Thierry
