Hello everyone,
I'll be more specific in my question, especially since I have done
some more progress today.
I have created a OpenGL-enabled drawing area and I can see the live
video feed in it. Neat. Now, I need to set the client-draw-callback of
the glimagesink element in my pipeline to a Python callback I define
in my application. This is to be able to draw the image in different
way than the default one. The tests/examples/generic/cube example in
gst-plugins-gl illustrates this in C. In Python, passing it a Python
callback throws an error. See
http://stackoverflow.com/questions/1834990/pygst-glimagesink-callbackfor a report of this problem.
To try out the pipeline I am building, see
http://bitbucket.org/aalex/toonloop1/src/8dd3fb06d81e/proto/gstgltest.pyTry uncommenting the line 96, and it fails.
I guess we should use ctypes or some kind of C-Python tool to overcome this?
There is probbly something that could be done in the element's C code
to fix this for every Python user at once.
Thank you !
Alexandre
