There is a comment on SdpEndpoint.conf.json file which states “WARNING: Usage of properties is not yet supported” . Is it working now?

File path: /etc/kurento/modules/kurento/SdpEndpoint.conf.json

{  
“numAudioMedias”: 1,  
“numVideoMedias”: 1,  
“audioCodecs”: [  
{  
“name”: “opus/48000/2”,  
“//”: “Next is an example about how a codec can be configured.”,  
“//”: “WARNING: Usage of properties is not yet supported”,  
“//properties”: {  
“//maxcodedaudiobandwidth”: “16000”,  
“//maxaveragebitrate”: “20000”,  
“//stereo”: “1”,  
“//useinbandfec”: “1”,  
“//usedtx”: “0”  
}  
},  
{ “name”: “PCMU/8000” },  
{ “name”: “AMR/8000” }  
],  
“videoCodecs”: [  
{ “name”: “VP8/90000” },  
{ “name”: “H264/90000” }  
]  
}

You can test it, but it seems it is not supported.
