The `on_connect` hook is firing more than one time when sending the transcoder output to another vhost.

[basemkhirat]

I am transcoding to 360p and sending the output to another vhost which named by the engine name.

I am using on_connect and but It's firing twice.

One when connecting the origin vhost and the other when SRS connected internally to the quality host.

To authenticate, I send a secret with the stream_key like stream_key?secret=09mY6AsPSeSF and check it using on_connect hook. like what implemented in srs-cloud.

The data sent from SRS to the first on_connect request:

{
  "server_id":"vid-776x7h7",
  "service_id":"j0356409",
  "action":"on_connect",
  "client_id":"2u38x628",
  "ip":"127.0.0.1",
  "vhost":"site.streamer",
  "app":"test-app",
  "stream":"stream_key",
  "param":"?vhost=site.streamer&secret=09mY6AsPSeSF",
  "tcUrl":"rtmp:\/\/127.0.0.1:1935\/test-app",
  "pageUrl":""
}

And the data sent from SRS to the second on_connect request:

{
  "server_id":"vid-776x7h7",
  "service_id":"j0356409",
  "action":"on_connect",
  "client_id":"5z3833fo",
  "ip":"127.0.0.1",
  "vhost":"site.streamer",
  "app":"test-app",
  "stream":"stream_key",
  "param":"?vhost=site.streamer?vhost=site.streamer",
  "tcUrl":"rtmp:\/\/127.0.0.1:1935\/test-app?vhost=site.streamer",
  "pageUrl":""
}

And the last one not having the secret, so it will fail to connect.

    }

        on_hls http://localhost:8000/v1/hooks/on_hls;
   }

}       

Is there a method to allow firing on_connect once? or a method to forward the secret to the other vhost to be authenticated also, or recommned another authentication method to do this.

This issue is related to the HTTP callback bug.

As a workaround, you can manage the FFmpeg process independently, since the transcoder is essentially an FFmpeg process. By managing FFmpeg yourself, you can bypass this bug.

You can add [param] after the output as follows, and try again.

transcode {
        enabled     on;
        ffmpeg     /usr/local/bin/ffmpeg;

        engine 360p {
            enabled         on;
            ... ...
            output   rtmp://127.0.0.1:[port]/[app]/[stream][param];
        }
}
