From 24882e924af2c0d8576970440d92ac5b4eb25bc8 Mon Sep 17 00:00:00 2001 From: Arun Raghavan Date: Mon, 21 Nov 2011 23:27:08 +0530 Subject: audio-src,audio-sink: Use lower latency values on pulsesrc/pulsesink This sets the pulsesink and pulsesrc buffer/latency parameters to be lower and more voip-friendly. If the system cannot provide or keep up with these values, PulseAudio will automatically try to adapt and provide larger values that are achievable. https://bugzilla.gnome.org/show_bug.cgi?id=663124 --- src/empathy-audio-sink.c | 4 ++++ src/empathy-audio-src.c | 3 +++ 2 files changed, 7 insertions(+) diff --git a/src/empathy-audio-sink.c b/src/empathy-audio-sink.c index d912e1d2d..5ab14b541 100644 --- a/src/empathy-audio-sink.c +++ b/src/empathy-audio-sink.c @@ -220,6 +220,10 @@ create_sink (EmpathyGstAudioSink *self) empathy_call_set_stream_properties (sink, self->priv->echo_cancel); + /* Set latency (buffering on the PulseAudio side) of 40ms and transfer data + * in 10ms chunks */ + g_object_set (sink, "buffer-time", 40000, "latency-time", 10000, NULL); + return sink; } diff --git a/src/empathy-audio-src.c b/src/empathy-audio-src.c index 635c87d24..aa271fa1c 100644 --- a/src/empathy-audio-src.c +++ b/src/empathy-audio-src.c @@ -331,6 +331,9 @@ create_src (void) empathy_call_set_stream_properties (src, TRUE); + /* Set latency (buffering on the PulseAudio side) of 20ms */ + g_object_set (src, "buffer-time", 20000, NULL); + return src; } -- cgit v1.2.3
