Phonon

PHONON_BACKEND

Load a specific backend. The backend name must be the backend plugin name without file extension. For example "phonon_vlc" for the VLC backend. Mind that the backend must be in the Phonon or Qt plugin path.

PHONON_DEBUG

Set to a value between 0 and 5 to define verbosity of debug output.

PHONON_PAINT (QML Branch only)

Set to change painting method of VideoGraphicsObject and QML VideoOutput. Can be:

  • qpainter to force QPainter (will create an RGB32 QImage)
  • Only working when a QGLContext is present (i.e. the output/object is in a QGraphicsView with QGLWidget viewport)
    • glsl for GLSL shader painting
    • glarb for GLARB shader painting
    • qglcontext to force painting via context builtin functions (will create an RGB32 QImage)

PHONON_PLATFORMPLUGIN

Set to the full path of a platform plugin to make it preferred choice over autodetected plugins.

PHONON_PULSEAUDIO_DEBUG

Set to a value between 0 and 5 to define verbosity of PulseAudio debug output.

PHONON_PULSEAUDIO_DISABLE

Set to any number to deactivate PulseAudio integration completely. This can also be implicitly achieved by setting QT_NO_GLIB to 1.

Phonon GStreamer

PHONON_GST_ALL_EFFECTS

Set to C integer boolean to allow listing of all effect plugins known to GStreamer.

PHONON_GST_AUDIOSINK

Set to a valid GStreamer audiosink name to force a specific sink (ignored when PulseAudio support is active)

PHONON_GST_FPS

Set to anything to activate display of frames per second. This only works with videomode software.

PHONON_GST_DEBUG

Set to value between 0 and 5 to define the verbosity of debug output.

PHONON_GST_GST_DEBUG

Set to value between 0 and 8 to define the debug level for GStreamer itself.

PHONON_GST_VIDEOMODE

Forces a painting method on the GStreamer VideoWidget. Can be:

  • opengl only if built with OpenGL support
  • software paint using QPainter and intermediate creation of a QImage
  • xwindow only available on X11, uses X11 overlay painting

TEGRA_GST_OPENMAX

Activates OpenMAX support on Tegra graphics setups. This only works with xwindow videomode.

Phonon VLC

PHONON_VLC_DEBUG

Set to value between 0 and 5 to define the verbosity of debug output. This value is also controlling the libvlc verbosity currently.
