Expected behavior of the wanted feature
I see you can use the following --osd-back-color=<color> to change the color of the background of OSD bars but this also adds a background color rectangle to the text as well, which is not desired.
Maybe can add an option to only change the background color behind the bars themselves without adding background to the text.
If added, no sure how specific this should be if there should be an option to only do this for OSD Volume Bar and only do this for OSB Duration Bar.
Thank You
