Original commit message from CVS: * ext/alsa/gstalsa.c: (gst_alsa_get_caps_internal): buffer-frames property was missing * ext/arts/gst_arts.c: rate missing from sinkcaps * ext/audiofile/gstafparse.c: * ext/audiofile/gstafsink.c: * ext/audiofile/gstafsrc.c: * ext/swfdec/gstswfdec.c: int audio doesn't know buffer-frames * ext/cdparanoia/gstcdparanoia.c: int audio doesn't know chunksize either * ext/nas/nassink.c: it's endianness, not endianess * gst-libs/gst/audio/audio.h: make float standard pad template caps really describe float * gst/law/mulaw.c: (linear_factory): signed only, please * gst/mpegstream/gstdvddemux.c: widths of 20 are not valid
