Additional context
hi, @lminiero
I am the maintainer of Janus-cloud (https://github.com/OpenSight/janus-cloud), which is a orchestrator of Janus-gateway. When I try to support the cascade feature for Janus-gateway, I found I don't know about"audiolevel_ext_id""videoorient_ext_id""playoutdelay_ext_id" info of remote publisher when invoking "add_remote_publisher" and "update_remote_publisher" request. The other stream's info, like type, code, mid, can be retrieved from the reply of the "publish" request for the original publisher. So, maybe Janus-gateway can add these stream's info （"audiolevel_ext_id""videoorient_ext_id""playoutdelay_ext_id" ） to the reply of "publish/configure" request of the normal publisher in next version. The current code which return the publisher's stream info is like below:
while(temp) {
......
temp = temp->next;
/* Add to the info we send back to the publisher */
json_t *info = json_object();
json_object_set_new(info, "type", json_string(janus_videoroom_media_str(ps->type)));
json_object_set_new(info, "mindex", json_integer(ps->mindex));
json_object_set_new(info, "mid", json_string(ps->mid));
if(ps->disabled) {
json_object_set_new(info, "disabled", json_true());
} else {
if(ps->description)
json_object_set_new(info, "description", json_string(ps->description));
if(ps->type == JANUS_VIDEOROOM_MEDIA_AUDIO) {
json_object_set_new(info, "codec", json_string(janus_audiocodec_name(ps->acodec)));
if(ps->acodec == JANUS_AUDIOCODEC_OPUS) {
if(ps->opusstereo)
json_object_set_new(info, "stereo", json_true());
if(ps->opusfec)
json_object_set_new(info, "fec", json_true());
if(ps->opusdtx)
json_object_set_new(info, "dtx", json_true());
}
} else if(ps->type == JANUS_VIDEOROOM_MEDIA_VIDEO) {
json_object_set_new(info, "codec", json_string(janus_videocodec_name(ps->vcodec)));
if(ps->vcodec == JANUS_VIDEOCODEC_H264 && ps->h264_profile != NULL)
json_object_set_new(info, "h264_profile", json_string(ps->h264_profile));
else if(ps->vcodec == JANUS_VIDEOCODEC_VP9 && ps->vp9_profile != NULL)
json_object_set_new(info, "vp9_profile", json_string(ps->vp9_profile));
if(ps->simulcast)
json_object_set_new(info, "simulcast", json_true());
if(ps->svc)
json_object_set_new(info, "svc", json_true());
}
}
json_array_append_new(media, info);
}
If Janus-gateway can return "audiolevel_ext_id""videoorient_ext_id""playoutdelay_ext_id" for the normal publisher, it's more convenient for orchestrator to create the remote publisher. Thanks
