          Components: Codecs/codec_opus
    Affects Versions: 16.1.1
         Environment: codec_opus: Remote package version 16.0_1.3.0 (263680) from http://downloads.digium.com/pub/telephony/codec_opus/asterisk-16.0/x86-64/codec_opus-16.0_1.3.0-x86_64.tar.gz

Hello,

configuration samples ({{configs/samples/codecs.conf.sample}}) provide the following explanation for two {{codec_opus}} options:

{noformat}
;max_playback_rate= ; Override the maximum playback rate in the offer's SDP.
                    ; Any value between 8000 and 48000 (inclusive) is valid,
                    ; however typically it should match one of the usual opus
                    ; bandwidths. A value of "sdp" is also allowed. When set
                    ; to "sdp" then the value from the offer's SDP is used.
                    ; (default: "sdp")
;bitrate= ; Override the maximum average bitrate in the offer's SDP. Any value
          ; between 500 and 512000 is valid. The following values are also
          ; allowed: auto, max, sdp. When set to "sdp" then the value from
          ; the offer's sdp is used. (default: "sdp")
{noformat}

but explicitly setting

{noformat}
max_playback_rate=sdp
bitrate=sdp
{noformat}

in a valid {{type=opus}} section results in an error like

{noformat}
config_options.c:798 aco_process_var: Error parsing bitrate=sdp [...]
{noformat}

when left to the default values, set to numeric values or to other documented values, there are no errors.

Maybe the samples are outdated or {{codec_opus}} needs to be fixed to correctly parse these options?

Thank you in advance for your help.
