From 760a84126172a7f25343e8dcca26313245702ec4 Mon Sep 17 00:00:00 2001 From: "Ronald S. Bultje" Date: Fri, 10 Oct 2003 12:24:20 +0000 Subject: [PATCH] Make GstMixerTrack a GObject. I also want to make it emit several signals, starting work is in here but it's not full... Original commit message from CVS: Make GstMixerTrack a GObject. I also want to make it emit several signals, starting work is in here but it's not fully implemented yet. for OSS, this will cause issues, but for ALSA, this is all automated. --- gst-libs/gst/interfaces/mixer.c | 4 +- gst-libs/gst/interfaces/mixer.h | 29 +------ gst-libs/gst/interfaces/mixertrack.c | 122 +++++++++++++++++++++++++++ gst-libs/gst/interfaces/mixertrack.h | 86 +++++++++++++++++++ gst-libs/gst/mixer/Makefile.am | 17 ++-- gst-libs/gst/mixer/mixer.c | 4 +- gst-libs/gst/mixer/mixer.h | 29 +------ gst-libs/gst/mixer/mixertrack.c | 122 +++++++++++++++++++++++++++ gst-libs/gst/mixer/mixertrack.h | 86 +++++++++++++++++++ 9 files changed, 433 insertions(+), 66 deletions(-) create mode 100644 gst-libs/gst/interfaces/mixertrack.c create mode 100644 gst-libs/gst/interfaces/mixertrack.h create mode 100644 gst-libs/gst/mixer/mixertrack.c create mode 100644 gst-libs/gst/mixer/mixertrack.h diff --git a/gst-libs/gst/interfaces/mixer.c b/gst-libs/gst/interfaces/mixer.c index 8dbc6ad564..28d10e6a24 100644 --- a/gst-libs/gst/interfaces/mixer.c +++ b/gst-libs/gst/interfaces/mixer.c @@ -23,7 +23,7 @@ #include "config.h" #endif -#include +#include "mixer.h" static void gst_mixer_class_init (GstMixerClass *klass); @@ -67,7 +67,7 @@ gst_mixer_class_init (GstMixerClass *klass) } const GList * -gst_mixer_list_tracks (GstMixer *mixer) +gst_mixer_list_tracks (GstMixer *mixer) { GstMixerClass *klass = GST_MIXER_GET_CLASS (mixer); diff --git a/gst-libs/gst/interfaces/mixer.h b/gst-libs/gst/interfaces/mixer.h index 5639758e4d..6ee49e3ac0 100644 --- a/gst-libs/gst/interfaces/mixer.h +++ b/gst-libs/gst/interfaces/mixer.h @@ -23,6 +23,7 @@ #define __GST_MIXER_H__ #include +#include G_BEGIN_DECLS @@ -39,34 +40,6 @@ G_BEGIN_DECLS #define GST_MIXER_GET_CLASS(inst) \ (G_TYPE_INSTANCE_GET_INTERFACE ((inst), GST_TYPE_MIXER, GstMixerClass)) -/* In this interface, a `track' is a unit of recording or playback, pretty much - * equivalent to what comes in or goes out through a GstPad.
