sdp transform error

I am rearranging the order of the codecs so that h264 is first but on android to ios calls im getting an encoding undefined error on one of the callbacks on RCTPeerConnection.

As I have seen in my logs, Is it because android does not have h264? @zxcpoiu @saghul

//check and replace for H264 codec
function preferH264(description) {
  let newDescription = description;
  let sdp = description.sdp;
  let parsedSdp = transform.parse(sdp);

  parsedSdp.media = parsedSdp.media.map(media => {
    if(media.type === 'video') {
      const baseRtp = [media.rtp.find(rtp => rtp.codec.toLowerCase() === 'h264')];
      media.rtp = baseRtp.concat(media.rtp);
    }

    return media;
  });

  newDescription.sdp = transform.write(parsedSdp);

  return newDescription;
}

@jjdp you are adding an undefined into the rtp list in cases where the codec is not found…

One of the easiest way to see which codec it supports, is to create offer without any constraints then see the codec list in sdp in different platform.
