Hello, i am writing a small python script where i need to loop through a
list of audio streams from gstreamer (just like gnome-volume-control under
applications). I have tried to look through the source code of gnome-media
and gnome-volume-control to see how they do it, but i just really can't
see how i am supposed to do it in python.
As far as i can see they get the list of streams from here
control->priv->all_streams, where control is a GvcMixerControl object,
which i really don't know how gets into the picture, and i figured maybe
someone here would know, or at least be able to point me in the right
direction.
This is the C code which i have found which concerns my question:
--- gvc-mixer-dialog.c --
streams = gvc_mixer_control_get_streams (self->priv->mixer_control);
for (l = streams; l != NULL; l = l->next) {
stream = l->data;
add_stream (self, stream);
}
g_slist_free (streams);
cards = gvc_mixer_control_get_cards (self->priv->mixer_control);
for (l = cards; l != NULL; l = l->next) {
card = l->data;
add_card (self, card);
}
g_slist_free (cards);
--- gvc-mixer-control.c ---
GSList *
gvc_mixer_control_get_streams (GvcMixerControl *control)
{
GSList *retval;
g_return_val_if_fail (GVC_IS_MIXER_CONTROL (control), NULL);
retval = NULL;
g_hash_table_foreach (control->priv->all_streams,
listify_hash_values_hfunc,
&retval);
return g_slist_sort (retval, (GCompareFunc) gvc_stream_collate);
}
--- gvc-mixer-control.c ---
GSList *
gvc_mixer_control_get_sinks (GvcMixerControl *control)
{
GSList *retval;
g_return_val_if_fail (GVC_IS_MIXER_CONTROL (control), NULL);
retval = NULL;
g_hash_table_foreach (control->priv->sinks,
listify_hash_values_hfunc,
&retval);
return g_slist_sort (retval, (GCompareFunc) gvc_stream_collate);
}
