= Audio Bar Graph over Video =

This section specifies how to enable the audiobargraph audio filter and video overlay, (mostly) via the GUI.  This displays an audio meter overlaid on the video.

There are three parts - an audio filter, which sends it's output via TCP to the Remote Control (RC) Interface.  This information is then picked up and displayed by the Audio Bar Graph video subpicture filter (OSD).

To enable this, VLC needs to be started with the '''--rc-host''' command-line switch - e.g.
 '''"C:\Program Files\VideoLAN\VLC\vlc.exe" --rc-host localhost:12345'''

In the GUI, set the following (this example from VLC v1.1.9 on Windows 7):
* Preferences:Show settings:All
* Audio/Filters > Enable "Audio part of the BarGraph function"
* Audio/Filters/audiobargraph > use defaults, change "Sends the barGraph information every n audio packets" to 1 to enable see a more accurate display
* Interface/Main interfaces > Enable "Remote control interface"
* Interface/Main interfaces/RC > Enable "Do not open a DOS command box interface"
* Video/Subtitles-OSD > Enable "Audio Bar Graph Video sub filter"
* Video/Subtitles-OSD/Audio Bar Graph > Set the following settings:
** "Value of the audio channels levels" = 0 (setting this to 0:1 crashes VLC v1.1.9)
** "X coordinate" = 0
** "Y coordinate" = 0 (this doesn't seem to affect anything)
** "Transparency of the bargraph" = 128 for 50% transparency which looks ok
** "Bargraph position" = Left (seems to only work Left,Center,Right - can't go top or bottom)
** "Alarm" = 1 (enables the silence alarm - puts a red border around the bargraph if silent for too long)
** "Bar width in pixel" = 10 (20 if you want it to be really visible)
