From a1bc7578243bd93e106fc426374363da16652797 Mon Sep 17 00:00:00 2001 From: Juergen Keil Date: Mon, 11 Mar 2002 19:58:00 +0000 Subject: Add a "control" method to the audio drivers, to allow pause/resume of the playback stream and to flush buffered samples from from the audio driver. (Currently implemented in the 'Sun' audio driver, + some untested code in the alsa 0.9 driver). The pause/resume method can be used by the engine to immediatelly stop playing buffered audio samples when the video is paused. Flushing buffered samples is useful when a video is stopped. And it'll be useful for better seeking support, too.
