My main question is what is the image and sound container passed back to Python?
This single thing along would be worth a SoC if it could be implemented across
Will your image objects be transferrable to PIL, Pygame, PyOpengl, Numpy,
Pythonmagick, Pycairo, wxPython, etc? It would be best if this could avoid the
"fromstring/tostring" mojo that always requires and extra copy of the data for
If the core numpy arrays could ever get added to the Python standard library,
this problem would be mostly solved. I believe there was a SoC for Python last
year for this exact array problem.
Your proposal sounds dangerously close to implementing some file demuxing by
yourself. Do not dare touch any of the file bits in your own library. This
proposal should only be for getting data from existing decompression libraries
into some general Python container.
