mplayerstart version 1.4.2
Creates resume file for resumable playback; disables X, KDE, and Gnome
screensavers; restores last volume levels; starts mplayer in full-screen
mode; sends output to selected display.
Usage: mplayerstart [OPTIONS] ~/video/movie1.avi
       mplayerstart [OPTIONS] ~/.mplayerstart/movie1.avi.resume
       mplayerstart --resumelast
       mplayerstart --resumepre
       mplayerstart --rewind
       mplayerstart --tvmode MODE
Options:
--tv                sends output to TV Display
                      ignored when playing audio; overrides tvmode setting
--tvmode off        sets TV-out mode off for future videos
                      also cancels '--tvmode once'
--tvmode on         sets TV-out mode on for future videos
--tvmode auto       sets TV-out mode to auto-detect for future videos
                      video will play on current display
                      only works with separate X screens, not xinerama
--tvmode once       prepares to play only the next video on TV-out
                      overrides prior tvmode for next play only
--resume            resumes playing file from last stop point
--resumelast        resumes playing last played media file
--resumepre         resumes playing previous-to-last played media file
--rewind            deletes last played resume file
--mopt "OPTIONS"    passes additional playback OPTIONS to mplayer
Note: Resume files are auto-deleted after 60 days.
Current data folder for resume files: $data
Current TV option: $tvx
Default Mplayer options: $moptions
