[vlc-devel] Can't Embed VLC in Qt4/wx on OSX with PyQt4/wx and Python Bindings

Also, to address Olivier's point ("Maybe their patch should be ported to the
new VLC version?"), I have tried that. The contents of voutgl.m in "macosx"
are nearly identical to voutagl.m in "minimal_macosx", so I tried porting
the patch, but it had no effect.

I also tried applying the patch to "macosx" but that still resulted in VLC
Goldeneye crashing (only when the macosx plugin is forcefully not compiled,
forcing VLC to use minimal_macosx, is it possible to start a video with
python-ctypes bindings without causing a crash in OS X).
