Original commit message from CVS: * gst/interleave/interleave.c: (gst_interleave_pad_get_type), (gst_interleave_pad_get_property), (gst_interleave_pad_class_init), (gst_interleave_request_new_pad), (gst_interleave_release_pad): * gst/interleave/interleave.h: Use an always increasing integer for the number in the name of the requested sink pads to guarantuee a unique name. Add a "channel" property to GstInterleavePad to make it possible for applications to retrieve the channel number in the output for every pad. Use g_type_register_static_simple() instead of g_type_register_static() to save some relocations.
