Published Option

opus.fmtp

Default Value: useinbandfec=1
Valid Values: [useinbandfec=(0|1)] [; maxaveragebitrate=(6000-510000)]
Changes Take Effect: At start/restart

Specifies the default OPUS fmtp option string used by the platform when initiating SDP offer or answering SDP offer. If the fmtp parameter is empty, the fmtp attribute line for OPUS will not be present in SDP offered by the platform.
The supported fmtp parameters are:
"useinbandfec" specifies whether MCP will take advantage of Opus in-band FEC or not. Opus in-band FEC helps mitigate errors when unstable transmissions occur. Possible values for "useinbandfec" are 1 and 0. If no value is specified, then in-band FEC will not be applied. For better error recovering results, the corresponding "maxaveragebitrate" should be set to a higher value, e.g. 48000.
"maxaveragebitrate" specifies the maximum average bitrate. Sending out this ftmp serves as a mandate to the remote end to not send a stream with average birate higher than the "maxaveragebitrate" value, as it might overload our network and/or receiver. Possible values for "maxaveragebitrate" are any integer in the range from 6000 to 510000 inclusive. If no value is specified, the bitrate will be automatically decided by MCP according to the audio source.
Unsupported fmtp parameters: usedtx; cbr; stereo; sprop-stereo; maxplaybackrate; sprop-maxcapturerate.
