Hello,
we have discussed setting variable marq-marquee with rpn function and VLM here:
viewtopic.php?t=18502

This question is about usage of rpn:
As I have tested, rpn function are not able to re-set variable marq in already running VLC.
If I try to apply rpn function vlc_var_set on several VLC_OBJECT_X, nothing will happen.
If I set marq-marquee by GUI intf and save preferences, change will manifest only in new VLC instance.
The only working way is run rc intf and set: marq-marquee myTEXT

So my question is: could be rpn function able re-set variables like marq-marquee, time_position,... dynamically in running VLC? I need to change marq-marquee with http intf for different broadcast elements.

Which OBJECT is marq-marquee variable child of? I am not able to find this.

Thank you
Albert

Hello,
there is a definition in /trunk/modules/control/rc.c

Code: Select all

/***************************************************************************** 
361  * RegisterCallbacks: Register callbacks to dynamic variables 
362  *****************************************************************************/ 
363 static void RegisterCallbacks( intf_thread_t *p_intf ) 
364 { 
365     /* Register commands that will be cleaned up upon object destruction */ 
...
   /* marquee on the fly items */ 
     var_Create( p_intf, "marq-marquee", VLC_VAR_VOID | VLC_VAR_ISCOMMAND ); 
     var_AddCallback( p_intf, "marq-marquee", Other, NULL ); 
...

which I suppose allows rc intf to change variables like marq-marquee by command.

My question: is it possible to add these definitions to /trunk/modules/control/http/http.c

Code: Select all

/***************************************************************************** 
  * Local prototypes 
  *****************************************************************************/ 
 static void Run          ( intf_thread_t *p_intf );

and use this function with rpn? (or somehow?)
Thank you
Albert
