wake up player on demand
The decoder should not wake up the player when it did not produce a flushed chunk. Move the decoder_wakeup_player() call to flushOutputBuffer() and invoke it only if the buffer was previously empty. git-svn-id: https://svn.musicpd.org/mpd/trunk@7336 09075e82-0dd4-0310-85a5-a0d7c8717e4f
