     Type:  enhancement   |     Status:  new
 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.9.1
 Keywords:                |       Port:  VLC
--------------------------+--------------------
 1. Desired enhancement: restore building VLC3 from source, which was
 removed in https://github.com/macports/macports-
 ports/commit/ddd6f4336c9cb206f76bc438e355a929425676b0

 2. It seems that Qt can be disabled altogether for VLC, and then there is
 nothing to prevent it from building in principle even on Tiger. Even with
 no GUI it should be perfectly usable, as long as the output is sent to X
 window.

 If the point 1 is too complicated to implement, maybe we can make `vlc-
 cli` port?
