# speed to some degree to ensure synchronous playback - can cause problems
# with some drivers and desktop environments.
#video-sync=display-resample

# Enable hardware decoding if available. Often, this does not work with all
# video outputs, but should work well with default settings on most systems.
# If performance or energy usage is an issue, forcing the vdpau or vaapi VOs
# may or may not help.
