go-mplayer - Go interface with the MPlayer slave-mode
Short module allowing the user to control a fork'd MPlayer process in slave-mode.
You can read all about the MPlayer slave protocol at mplayerhq.hu
Requirements
MPlayer should be installed and available in the current PATH
Example
This example launches MPlayer in the background, requests it to play a file, wait for 5 seconds then stop playback:
import (
"time"
"github.com/tamentis/go-mplayer"
)
mplayer.StartSlave()
mplayer.SendCommand("loadfile /tmp/myfile.mp3")
time.Sleep(5 * time.Seconds)
mplayer.SendCommand("stop")
This example uses the blocking command PlayAndWait(), it allows you to use the
module in a similar fashion to os/exec except that you can pre-load the
process to get a better response time (e.g. on slow hardware):
import (
"github.com/tamentis/go-mplayer"
)
mplayer.StartSlave()
mplayer.PlayAndWait("/tmp/myfile.mp3")

func SendCommand ¶
func SendCommand(msg string)
SendCommand feeds the MPlayer slave with input commands.
func StartSlave ¶
func StartSlave(errorHandler ErrorHandler)
StartSlave keeps an mplayer process in slave mode open for the rest of time, consuming input from the mplayerInput channel and feeding it to the stdin of the process. If the process dies it is restarted automatically.
You are required to define an error handler function that will be called with all the errors that could have occured managing the slave.
