Codec AVOption ab (set bitrate (in bits/s)) specified for output file #0 (udp://wowzaip:10000?pkt_size=1316) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
