Original commit message from CVS: 2005-12-26 Martin Soto <martinsoto@users.sourceforge.net> * gst/iec958/ac3iec.h: * gst/iec958/ac3iec.c: (NORMAL_CAPS_DEF, RAW_AUDIO_CAPS_DEF, ac3iec_class_init) (ac3iec_init, ac3iec_set_property, ac3iec_get_property): Add a raw-audio property to ac3iec958 that allows setting the source pad caps to raw audio instead of audio/x-iec958. This makes it possible to use ac3iec958 together with the normal alsasink element to drive an external receiver that autodetects AC3 content.
