| dtx | Boolean | no | false | Encoder's discontinuous transmission value. |
| fec | Boolean | yes | false | Encoder's forward error correction value. |
| max_bandwidth | Custom | full | false | Encoder's maximum bandwidth allowed. |
| max_playback_rate | Custom | 48000 | false | Encoder's maximum playback rate. |

Configuration Option Descriptions¶
application¶
-
voip -
audio -
low_delay
bitrate¶
Can be any number between 500 and 512000 as well as one of the following opus values:
-
auto -
max
cbr¶
True/False value where 0/false/no represents a variable bit rate and 1/true/yes is constant bit rate.
complexity¶
Can be any number between 0 and 10, inclusive. Note, 10 equals the highest complexity.
dtx¶
True/False value where 0/false/no represents disabled and 1/true/yes is enabled.
fec¶
True/False value where 0/false/no represents disabled and 1/true/yes is enabled.
max_bandwidth¶
Sets an upper bandwidth bound on the encoder. Can be any of the following:
-
narrow -
medium -
wide -
super_wide -
full
max_playback_rate¶
Any value between 8000 and 48000, inclusive. Although typically it should match one of the usual Opus bandwidths.
packet_loss¶
Can be any number between 0 and 100 (inclusive). Higher values result in a loss resistant behavior, however this has a cost on the quality (dependent upon a given bitrate).
signal¶
Aids in mode selection on the encoder:
-
auto -
voice -
music
