[vlc-devel] [PATCH 1/6] mmal: Move video_output plugin into hw/mmal module
Julian Scheel

Fri Aug 29 09:09:33 CEST 2014
As the mmal modules will require some shared code in the future move them out
of the split directory structure into a hw/mmal subdirectory, like it
is handled with vdpau plugins already.
