From d47be76ce09ab3de9dfd5989ea65ca305c723f73 Mon Sep 17 00:00:00 2001 From: Max Kellermann Date: Thu, 22 Jan 2009 16:06:47 +0100 Subject: [PATCH] null: added option to disable timer synchronization The null plugin synchronizes the playback so it will happen in real time. This patch adds a configuration option which disables this: the playback will then be as fast as possible. This can be useful to profile MPD. --- NEWS | 1 + src/output/null_plugin.c | 12 +++++++++++- 2 files changed, 12 insertions(+), 1 deletion(-) diff --git a/NEWS b/NEWS index 841a7b1bb..f3b5c58f9 100644 --- a/NEWS +++ b/NEWS @@ -11,6 +11,7 @@ ver 0.15 - (200?/??/??) - mikmod disabled by default, due to severe security issues in libmikmod * audio outputs: - shout: enlarged buffer size to 32 kB + - null: allow disabling synchronization * commands: - "playlistinfo" supports a range now - added "sticker database", command "sticker", which allows clients diff --git a/src/output/null_plugin.c b/src/output/null_plugin.c index a1eb0196f..7530a20cc 100644 --- a/src/output/null_plugin.c +++ b/src/output/null_plugin.c @@ -24,6 +24,8 @@ #include struct null_data { + bool sync; + Timer *timer; }; @@ -34,6 +36,7 @@ null_init(G_GNUC_UNUSED struct audio_output *audio_output, { struct null_data *nd = g_new(struct null_data, 1); + nd->sync = config_get_block_bool(param, "sync", true); nd->timer = NULL; return nd; @@ -54,7 +57,8 @@ null_open(void *data, struct audio_format *audio_format) { struct null_data *nd = data; - nd->timer = timer_new(audio_format); + if (nd->sync) + nd->timer = timer_new(audio_format); return true; } @@ -76,6 +80,9 @@ null_play(void *data, G_GNUC_UNUSED const char *chunk, size_t size) struct null_data *nd = data; Timer *timer = nd->timer; + if (!nd->sync) + return true; + if (!timer->started) timer_start(timer); else @@ -91,6 +98,9 @@ null_cancel(void *data) { struct null_data *nd = data; + if (!nd->sync) + return; + timer_reset(nd->timer); }
