Qt Interface

Introduction

Qt / Qt4 is the default, plain, graphical, interface to VLC, made using the Qt library (Linux users may need to have this installed). It is used as the default interface on the Windows and Linux versions of VLC media player from version 0.9.0 and above.

Unless you change the preferences, VLC media player will start up in the Qt4 interface, but you can force this by running

vlc -I qt

or

qvlc

If Qt4 is not avaliable, it will probably revert to using the rc (console) interface, even if you force it. The most likely reason for this is if Qt4 hasn't been installed, or if it wasn't linked in (using the ./configure). See compiling VLC [1] for information on compiling.

Please note that the pre 0.9.0 wxWidgets interface is replaced by the Qt interface and will thus not be further developed.

Main interface Description

Status Bar

The Status Bar has three distinctive portions displaying information.

• Name label
• Speed label
• Time label

Here are the actions you can do on the status bar:

	Select	Left Click	Right Click	Middle Click	Double Click
Name label	Prepare for copy	Give focus for arrows selection	Copy menu	-	Word selection
Speed label	-	-	Show fine rate speed adjusting	-	reset to normal 1.00x speed
Time label	-	Switch remaining/elasped time	Switch remaining/elasped time	Switch remaining/elasped time	Open the "Go To Time" dialog

Time label

The timeLabel shows mm:ss/nn:tt in the statusBar.

If the time is longer that one hour, it shows hh:mm:ss/ii:nn:tt.

If you click on it, it shows remaining time instead of elapsed time. If you double click on it, it opens the open the GOTOTime dialog in order to skip easily.

If vlc doesn't know the total time, like in avi/http, it shows the elapsed time only, and --:-- instead of total time.

Controller

Main Slider

The main slider does control the timeline.

When you click somewhere on the timeline, it skips the movie to that place. When you drag the slider of the timeline, it follows the position on the movie.

When you hover it with your mouse, it shows you where it would go if you click.

Sound Slider

The sound slider does control the volume.

When you click somewhere on the soundSlider, it changes the volume. When you click and drag on the soundSlider, it changes the volume too. If you release the click really outside of the volume slider, it will reset to your old value

When you hover it with your mouse, it shows you the volume it would be if you click it.

Sound range

The sound goes from 0% to 200% and can go up to 400%

100% means normal output of the file without amplification. Above 100% means that it may use software amplification, and it could distort sound (it usually doesn't, but it could).

Dialogs description

Extended Dialog

The Extended settings dialog box can be brought up by selected the Ex button on the main window. Alternatively it can be found in Tools menu under Extended settings... (Ctrl+E). The extended settings allow effects to be enabled and adjusted in realtime whilst media is playing.

Audio Effects

Graphic Equalizer

The Graphic equalizer enables the equalization of the sound output to be enabled and adjusted. Tick the Enable tickbox to enable it. Ticking the 2 pass will mean the sound is reprocessed through the equalizer again, thus amplifying the changes. Slide the sliders to adjust the output levels for the preamp and each frequency range. There are a number of presets which can be selected from the drop-down box.

Spatializer

The Spatializer contain several adjustable audio filters to change the perceived environment such as room size and humidity. Tick the Enable spatializer tickbox to enable and adjust the sliders.

Video Effects

Advanced video filter controls

A colon separated list will be generated when filters and effects in the other video tabs are enabled. The list of effect can be modified. Press the Update button to apply the changes.
