``--cursor-autohide``.
``--audio-delay=<sec>``
Audio delay in seconds (positive or negative float value). Negative values
delay the audio, and positive values delay the video.
Audio delay in seconds (positive or negative float value). Positive values
delay the audio, and negative values delay the video.
``--deinterlace=<yes|no|auto>``
Enable or disable interlacing (default: auto, which usually means no).
