Original commit message from CVS: * ext/esd/esdsink.c: (gst_esdsink_class_init): Remove property that handles osssink fallback. * gst/audioconvert/gstaudioconvert.c: (gst_audio_convert_init), (gst_audio_convert_getcaps): * gst/qtdemux/qtdemux.c: (qtdemux_audio_caps): Add audio/x-qdm2 for QDM2 audio. * gst/sine/gstsinesrc.c: (gst_sinesrc_get): * gst/sine/gstsinesrc.h: Add example of how to implement tags. * gst/videoscale/gstvideoscale.c: (gst_videoscale_getcaps): Decrease minimum size to 16x16. * gst/wavparse/gstwavparse.c: Convert disabled pad template caps to new caps. * sys/ximage/ximagesink.c: (gst_ximagesink_xcontext_get): * sys/xvimage/xvimagesink.c: (gst_xvimagesink_xcontext_get), (gst_xvimagesink_chain): Throw element error when display cannot be opened. Increase minimum framerate to 1.0. Check the data free function on a buffer to make sure it is the type we expect before manipulating it.
