Original commit message from CVS: * ext/flac/gstflacdec.c: (gst_flac_dec_metadata_callback), (gst_flac_dec_write): Support decoding of all depths between 4 and 32 bits and read the depth from the streaminfo header if needed. Also support all sampling rates between 1 and 655350 Hz. * ext/flac/gstflacenc.c: (gst_flac_enc_caps_append_structure_with_widths), (gst_flac_enc_sink_getcaps), (gst_flac_enc_sink_setcaps), (gst_flac_enc_chain): * ext/flac/gstflacenc.h: Support encoding in all bit depths supported by the streamable subformat (i.e. 8, 12, 16, 20 and 24 bits) and all sampling rates between 1 Hz and 655350 Hz.
