mkfifo /tmp/mplayer-input
mplayer -slave -idle -input file=/tmp/mplayer-input abc.avi
void  init_your_stuff (void)
{
// Go the hard way, it's late here
system ("mkfifo /tmp/mplayer-input");
// launch the player with abc.wmv
system ("mplayer -slave -idle -quiet -input file=/tmp/mplayer-input abc.wmv
\n");
}

main()

 {
  init_your_stuff;
  ...
  ...
//do something, anything you want to
  ...
//we need to pause a bit now to go and get some chips
 system("echo p > /tmp/mplayer-input");

// you can do it nicer 'a la C'  with fopen and fprintf($file,"p")
fclose....

//we are back with chips, unpause it
 system("echo 'p' > /tmp/mplayer-input");

This does what you want.

In order to send commands to mplayer, you need to open a tube
(/tmp/mplayer-input) to send them.
