Hello all,

How to refresh regularly (1 second in the example) the OSD message to regularly get stats for the streaming link (input_bitrate,...)

I'm very beginner in Lua scripting, I tryed this code but it display the message only one time and it doesn't refresh the data, i already read in the forum that the vlc.misc.mwait function don't work on VLC 2.x.x (2.1.3 in my case)

Code: Select all

function meta_changed()
   -- related to capabilities={"meta-listener"} in descriptor()
   -- triggered by available media input meta data?
   local channel1 = vlc.osd.channel_register()
   local channel = vlc.osd.channel_register()
while vlc.input.is_playing() do 
      local systemTime = os.date("%H:%M:%S") 
	  
      vlc.osd.message(systemTime,channel1,"top-right",5000000) 
	  vlc.osd.message(get_stat(),channel,"top-left",5000000)
      sleep(1)
   end
end

function get_stat()
	local input_item = vlc.input.item()
	local stat = input_item:stats()
	return stat.input_bitrate
end

function sleep(sec)
   local t = vlc.misc.mdate()
   vlc.misc.mwait(t + sec*1000*1000)
end

What can I use in my case ?

vlc.misc.mwait() is available in interface scripts. It is available in extensions scripts in VLC-1.1.x.
VLC-2.0.x, while playing media:

Code: Select all

...
    vlc.var.add_callback(vlc.object.input(), "intf-event", input_events_handler, "Hello world!")
...
function input_events_handler(var, old, new, data)
    ...
end

Check Time (lite) extension.
