Yes, I know that I can use an external buffer to fill it into the texture manually, but VLC does not provide hardware acceleration for rendering to an external buffer. Therefore, they created an API for direct rendering inside an OpenGL texture, but in your python-vlc module, the function that should be responsible for this is not realized

These functions are blacklisted because their signature and parameter types makes it not that easy to define automatic conversion to ctypes. If you want, you can contribute the appropriate ctypes wrapper definitions, I will gladly integrate them in the module.
