get rid visualization with video streams
It is ridiculous to have visualization with video streams, but we have it. I see some users want to have it for some special cases, but it should be considered as an exception. The worst thing happens when visualization windows (especially in full-screen mode) hide the video.
Yes, we can turn it off at any time. But if there is a playlist of mixed audio and video streams, it is annoying to do so every time especially when items switched automatically. Moreover, with a dummy interface, it is not possible at all.
So when we set visualization it should be disabled for video streams by default. To turn on visualization for both audio and video streams there should be a special separate option.
