ext/wavpack/gstwavpackenc.*: Use bitrate property solely for bitrates and add new bits-per-sample property for the ot...
Original commit message from CVS: Patch by: Sebastian Dröge <slomo at circular-chaos org> * ext/wavpack/gstwavpackenc.c: (gst_wavpack_enc_base_init), (gst_wavpack_enc_class_init), (gst_wavpack_enc_set_wp_config), (gst_wavpack_enc_chain), (gst_wavpack_enc_sink_event), (gst_wavpack_enc_set_property), (gst_wavpack_enc_get_property): * ext/wavpack/gstwavpackenc.h: Use bitrate property solely for bitrates and add new bits-per-sample property for the other stuff. Set duration to 'unknown' in initial header and resend header with proper duration on EOS; update Sebastian's e-mail address.
