Original commit message from CVS: * gst/rtp/Makefile.am: * gst/rtp/fnv1hash.c (MASK_24, FNV1_HASH_32_INIT, FNV1_HASH_32_PRIME, fnv1_hash_32_new, fnv1_hash_32_update, fnv1_hash_32_to_24): * gst/rtp/fnv1hash.h (__GST_FNV1_HASH_H__): Add a simple hashing implementation that we can use to generate a 24-bit ident value based on the codebooks for vorbis and theora. * gst/rtp/gstrtptheorapay.c (gst_rtp_theora_pay_finish_headers, gst_rtp_theora_pay_handle_buffer): * gst/rtp/gstrtpvorbisdepay.c (gst_rtp_vorbis_depay_parse_configuration, gst_rtp_vorbis_depay_switch_codebook, gst_rtp_vorbis_depay_process): * gst/rtp/gstrtpvorbispay.c (gst_rtp_vorbis_pay_reset_packet, gst_rtp_vorbis_pay_init_packet, gst_rtp_vorbis_pay_flush_packet, gst_rtp_vorbis_pay_finish_headers, gst_rtp_vorbis_pay_handle_buffer): Use the hashing function, ensuring that the same codebooks result in the same ident and thus the same SDP description. Various log fixes/changes.
