Tim-Philipp Müller 534e0c268e ext/alsa/: Helper functions to add device probing via the GstPropertyProbe interface to a class.
Original commit message from CVS:
* ext/alsa/Makefile.am:
* ext/alsa/gstalsadeviceprobe.c:
* ext/alsa/gstalsadeviceprobe.h:
Helper functions to add device probing via the GstPropertyProbe
interface to a class.
* ext/alsa/gstalsamixer.h:
Comment out GST_ALSA_MIXER, it returns a struct that's not
used.
* ext/alsa/gstalsamixer.c: (gst_alsa_mixer_open):
Add some debug info.
* ext/alsa/gstalsamixerelement.c:
(gst_alsa_mixer_element_interface_supported),
(gst_implements_interface_init),
(gst_alsa_mixer_element_init_interfaces),
(gst_alsa_mixer_element_class_init),
(gst_alsa_mixer_element_finalize), (gst_alsa_mixer_element_init),
(gst_alsa_mixer_element_set_property),
(gst_alsa_mixer_element_get_property),
(gst_alsa_mixer_element_change_state):
* ext/alsa/gstalsamixerelement.h:
Add 'device' and 'device-name' properties. Add GstPropertyProbe
for device handling (gnome-volume-control will need that).
