mplayer

Jump one Frame

Source

When having a movie paused, you can go to the next frame with the .-key. I haven't found a shortcut for a frame backward yet.

Screenshots

Source

Take a screenshot

  1. Start mplayer with screenshot support

bash mplayer -vf screenshot <file>

or put it in ~/.mplayer/config

bash vf=screenshot

  1. Press s to take a screenshot in the current pwd. For continous screenshots press S to start and S to stop it again.

Playspeed

Source

Increase the speed to play the video without changing the pitch of the audio.

alias mplayer='mplayer -af=scaletempo'

Alternative: add the parameter to the mplayer config file (~/.mplayer/config):

af=scaletempo
