From f18e52417639518545ebce3649f3ce3450bcb01c Mon Sep 17 00:00:00 2001 From: Eric Wong Date: Mon, 27 Aug 2007 09:36:11 +0000 Subject: send SIGSTOP to player and decoder processes on pause, too as with the stop command, this will cause the player and decoder to suspend and not wake up hundreds of times a second to poll a variable for wakeup. This will reduce power consumption on some CPUs while mpd is paused and not playing. tests: pause && unpause => OK pause && stop && play => OK pause && exit && restart w/statefile && unpause => OK pause && block sound device && \ unpause => failed to open sound device \ => still paused and suspended => unblock sound device && unpause => OK (playing) In all cases, the player process releases the audio device when paused before going into the suspended state. git-svn-id: https://svn.musicpd.org/mpd/trunk@6822 09075e82-0dd4-0310-85a5-a0d7c8717e4f --- src/player.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'src/player.c') diff --git a/src/player.c b/src/player.c index 096503b19..e84f31828 100644 --- a/src/player.c +++ b/src/player.c @@ -239,6 +239,7 @@ int playerStop(int fd) if (player_pid > 0 && pc->state != PLAYER_STATE_STOP) { pc->stop = 1; + kill(player_pid, SIGCONT); while (player_pid > 0 && pc->stop) my_usleep(1000); } @@ -266,6 +267,8 @@ int playerPause(int fd) if (player_pid > 0 && pc->state != PLAYER_STATE_STOP) { pc->pause = 1; + if (player_pid > 0 && pc->state == PLAYER_STATE_PAUSE) + kill(player_pid, SIGCONT); while (player_pid > 0 && pc->pause) my_usleep(1000); } -- cgit v1.2.3
