I’m streaming to RTP and my receiver requires CBR video and audio. I manage to get a transcoding profile to convert the video to CBR but I can’t find the matching audio setting to convert the audio to CBR.
Here’s what I did to convert to CBR video:
<Name>mainconcept.bit_rate_mode</Name>
<Value>0</Value>
<Type>Long</Type>
…
For audio, so far I have:
<Audio>
<Codec>AAC</Codec>
<Bitrate>64000</Bitrate>
</Audio>
I did turn on logAudioEncodingParameters but I don’t see any parameters that indicate how to set mainconcept encoder to use CBR for audio.
Here’s what I get in the access log:
long: channel copy: 0=donothing, 1=copy-left-over-right, 2=copy-right-over-left
mainconcept.channel_copy: 0
long: crc protection: 0=off, 1=on
