Hi~ all,
I want to know how can we get Mixer interfaces to control volumes in alsamixer.
I think that I can get pointer of GstMixer by using gst_implements_interface_cast().
but gst_element_implements_interface() always return FALSE.
Is it wrong method?
Please let me know how can I control alsamixer's volume.
 alsa_mix = gst_element_factory_make("alsamixer", "alsa mixer00");
 if( !gst_element_implements_interface(alsa_mix, GST_TYPE_MIXER) )
  g_warning("cannot found GST_TYPE_MIXER");
