Another option is to use external or internal TURN server or publish a stream via RTMP or RTSP.
Redundancy support while publishing audio
Since build 5.2.1969 a redundancy is supported while publishing audio data (RED, RFC2198). This allows to reduce audio packet loss when using opus codec. The feature may be enabled with the following parameter
| Code Block | ||
|---|---|---|
| ||
codecs=red,opus,alaw,ulaw,g729,speex16,g722,mpeg4-generic,telephone-event,h264,vp8,flv,mpv |
Note that red codec should be set before opus codec. In this case a browser supporting RED will send a redundancy data in audio packets. Note that audio publishing bitrate will be raised.
RED should be excluded for the cases when it cannot be applied:
| Code Block | ||
|---|---|---|
| ||
codecs_exclude_sip=red,mpeg4-generic,flv,mpv
codecs_exclude_sip_rtmp=red,opus,g729,g722,mpeg4-generic,vp8,mpv |
