[vlc-devel] [Videolan-devel] [PATCH] Add Dynamic CSA update functionality

[Kaloyan Kovachev]

just saw that vlc_mutex_init takes only one parameter now, so it should be just

+    vlc_mutex_init( &p_sys->demux_lock );

instead of 

+    vlc_mutex_init( p_demux, &p_demux->p_sys->demux_lock );
and
+    vlc_mutex_init( p_mux, &p_demux->p_sys->demux_lock );

If there is something else I should fix, will include this change too in the
next version of the patch
