The purpose of these packages is to provide as easy as possible installation experience for OpenCV Python bindings and they should work directly out-of-the-box.
Adding FFmpeg as an additional dependency without a "universal" FFmpeg build (e.g. LGPL licensed build like in the Windows wheels) the goal is considerably harder to achieve. This might change in the future.
**Q: Why I can't open GUI windows (``cv2.imshow()``) on GNU/Linux distribution X or on macOS?**
A: Like above, OpenCV was not compiled against GTK or Carbon. Support for these might be added in the future.
