Can i have several video codecs like this where the only difference is profile-level-id ?

router: {
  mediaCodecs: [
    {
      kind: "video",
      mimeType: "video/H264",
      clockRate: 90000,
      parameters: {
        "level-asymmetry-allowed": 1,
        "packetization-mode": 1,
        "profile-level-id": "42001f",
      },
    },
    {
      kind: "video",
      mimeType: "video/H264",
      clockRate: 90000,
      parameters: {
        "level-asymmetry-allowed": 1,
        "packetization-mode": 1,
        "profile-level-id": "42e01f",
      },
    },
  ];
}

If the device picks up the profile level id 42e01f (second codec in array) I cannot seem to read the stream from the consumer, the stream is sent with a webRtcTransport.

However, if I change the order of the codecs or remove the first one it works fine.

Same here. Wasn’t able to set codec profile-level-id in produce codec parameters on client-side even in config list array it’s exists. I need several codecs with same mimeType but different profile-level-ids. Did you find solution?
