Install the package.
Notable variants are:
- AUR - Development branch.
- AUR - Without X support.
- AUR - With Qt5 interface.
Notable optional dependencies are:
- - for the GUI
- - for audio CD playback support
VLC does not offer an option to change language in its Preferences menu. But you can use the LANGUAGE= prefix. For instance, modify the
Exec=LANGUAGE=fr /usr/bin/vlc %U
to switch VLC interface to French.
VLC can be "skinned" for a different look and feel. You can get skins at the skins website.
To install a skin download it and move it to:
Open up VLC, click Tools > Preferences. When the preferences window opens up you should be in the "Interface" tab
Choose the "Use custom skin" radio button, and select the downloaded skin.
Restart VLC for the change to take effect.
Run VLC with the parameter
--extraintf=http to use both the desktop and web interface. The
--http-host parameter specifies the address to, which is
localhost by default. To set a password, use
--http-password, otherwise VLC will not allow you to log in.
# vlc --extraintf=http --http-host 0.0.0.0:8080 --http-password 'yourpasswordhere'
Or you can enable this feature in the UI by navigating to View > Add Interface > Web Interface.
VLC defaults to port 8080: http://127.0.0.1:8080
/usr/share/vlc/lua/http/.hosts to allow remote connections. You will need to restart VLC in order for changes to take effect.
Tips and tricks
Twitch.tv streaming over VLC
Playing streamed content from a local DLNA server
If you find that trying to play uPNP/DLNA content (by going to View > Playlist > Local Network > Universal Plug'n'Play), that vlc fails to see the DLNA server on the local network, then make sure that the firewall is not blocking port 1900 UDP. It is essential that this port is open in order to play local uPNP/DLNA content.
Control using hotkeys or cli
Follow instructions in script to setup a socket for VLC.
Either run the script from the command line or register the script with keyboard shortcuts through your desktop.
Alternatively, you can use dbus-send as discussed here to interact with VLC:
$ dbus-send --print-reply --session --dest=org.mpris.MediaPlayer2.vlc /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.PlayPause
Preventing multiple instances
The default settings for VLC is to open a new instance of the program for each file that is opened. This can be annoying if you are using VLC for something like playing your music collection. You can disable this in Tools > Preferences > Interface > Instances > Allow only one instance. Optionally, tick Enqueue files when in one instance mode which keeps current file playing and adds any newly opened files to the current playlist.
Hardware acceleration support
VLC automatically tries to use an available API, but you can override it by going to Tools > Preferences > Input & Codecs and choosing the suitable option under Hardware-accelerated decoding, e.g.
Video Acceleration (VA) API for VA-API or
Video Decode and Presentation API for Unix (VDPAU) for VDPAU.
VLC's web interface can be started from systemd. First, you need to create a default user. This example will use UID 75 since it's not reserved according to DeveloperWiki:UID / GID Database.
# useradd -c "VLC daemon" -d / -G audio -M -p \! -r -s /bin/false -u 75 -U vlcd
Now create the systemd service file:
[Unit] Description=VideoOnLAN Service After=network.target [Service] Type=forking User=vlcd ExecStart=/usr/bin/vlc --daemon --syslog -I http --http-port 8090 --http-password password Restart=on-abort [Install] WantedBy=multi-user.target
Video broken or other issue after upgrade
Now and then VLC will have some issues with configuration even in minor releases. Before making bug reports, remove or rename your configuration located at
~/.config/vlc and confirm whether the issue is still there.
If using a ffmpeg variant from the AUR, be sure that you have upgraded it as well. Pacman will not upgrade it when necessary and a mismatch will break VLC.
When starting VLC you can get a segfault, and ruling out general factors such as Microcode, a possible workaround to this is running the following:
# /usr/lib/vlc/vlc-cache-gen -f /usr/lib/vlc/plugins
Then reinstall VLC.
Another workaround can be reinstalling vlc within an
# LD_PRELOAD=/usr/lib/libgobject-2.0.so.0 pacman -S vlc
This can happen under XFCE, there will be no more icons in dropdown menus, like the PCI card icon.
Execute these commands to reactivate these icons:
$ gconftool-2 --type boolean --set /desktop/gnome/interface/buttons_have_icons true $ gconftool-2 --type boolean --set /desktop/gnome/interface/menus_have_icons true
Failed to open VDPAU backend
Since your system probably doesn't support VDPAU you should tell VLC to use VA-API instead, see #Hardware acceleration support.
Video output overlaps the desktop, does not scale nor position properly
This happens at least on Intel cards, and a fix that reportedly solves the problem is setting the output in the video settings to OpenGL GLX (XCB) and the Input/Codecs decoding to VA-API (any of them).
No playback via SFTP of media files names containing spaces
If VLC does not play any videos or audio files over SFTP make sure you haveinstalled.
If it refuses to play any media files containing spaces via SFTP and always asks for authentication change the Exec line in the vlc.desktop file from
Exec=/usr/bin/vlc --started-from-file %U
Exec=/usr/bin/vlc --started-from-file %F
If you experience screen tearing while playing video, try setting Video output from Automatic to OpenGL Video Output (XCB) in preferences.
