To configure Parole, choose Tools → Preferences. This will bring up the Parole Settings dialog, which allows you to adjust Parole's behavior to your needs. The screenshots below all show the default settings.

Open Parole Preferences

Disable screensaver when playing movies

• Leaving this option ON will prevent the screensaver from activating due to keyboard inactivity during playback of movies.

Show visual effects when an audio file is played

• Turn this option on to see various visual effects displayed as a music selection is being played. The effects change dynamically in synchronization with the music.

Visualization type:

• This pick list is activated when visual effects are turned on and allows you to choose different types of effects.

Enable keyboard multimedia keys

• Enables keys like Volume, Play, Pause, Forward, Reverse, etc. on keyboards which are equipped with them.

You can select one of three backends for video playback. Note that this will have an impact on the performance, so if you notice choppy playback, you can try another backend. Also note that you have to restart Parole after switching to a different backend. While the Clutter and XV backend make use of hardware video acceleration, the “No XV” option uses (the usually slower) software acceleration.

Moving the sliders changes the color balance of the video being played or the audio effects being displayed (if visual effects are enabled). Changes can be applied while the media are playing and they take effect immediately. If you are unhappy with your changes, press the Reset to defaults button. Note that the color balance settings can only be changed when using one of the two “X Window System” options in the Video Output section above.
