mplayer-status

This script came about because I had a need to be able to query mplayer for various playback information. It can be used to query mplayer for the following information:

• mplayer process id (PID)
• media file name
• codec information
• playback time (seconds elapsed or timestamp)
• playback speed (as percentage)
• volume level (as integer 0-100)
• pause status
• mute status
• running status of mplayer (pauses or playing, is mplayer running with the media loaded)

Usage

By default, the player starts with volume at 50%. This default can be changed by editing my script and changing the value for the defaultVolume variable.

To utilize this script, pull it into another bash script by running eval $(cat /path/to/mplayer-with-status.sh). Then when you play a file from your main script, use the playMediaFile function to start mplayer.

Once playback of a media file has been started using the playMediaFile function, mplayer can be queried by issuing any of the following commands:

• getPID
• getMediaFileName
• getCodecInfo
• getElapsedTimestamp
• getElapsedSeconds
• getSpeed
• getVolume
• isPaused
• isMuted
• isFinishedPlaying

All of the functions that begin with get return a value. Functions that begin with is are intended to be executed as conditions (e.g. if isPaused or if ! isMuted or isMuted && do something).
