Stream not starting when sending OpenVidu rtmp to medialive/mediapackage

Hello i created a medialive/mediapackage stack using the worflow wizard as an rtmp push to push a stream from an OpenVidu application to the mediapackage channel, but when i start the stream i only get the preview, that one minute video in the mediapackage channel. From the logs of the server is used the following ffmpeg command to send the stream:

{
  "Image": "openvidu/openvidu-recording:2.26.0",
  "name": "broadcast_SessionABC",
  "Env": [
    "DEBUG_MODE=false",
    "CONTAINER_WORKING_MODE=BROADCAST",
    "BROADCAST_URL=MEDIA_LIVE_INPUT_URL",
    "ONLY_VIDEO=false",
    "RESOLUTION=640x360",
    "FRAMERATE=30",
    "BROADCAST_COMMAND=ffmpeg <./stop -y -progress pipe:1 -f alsa -i pulse -f x11grab -draw_mouse 0 -framerate $FRAMERATE -video_size $RESOLUTION -i :$DISPLAY_NUM -c:a aac -c:v libx264 -preset ultrafast -tune zerolatency -copyts -f flv $BROADCAST_URL"
  ],
  "HostConfig": {
    "AutoRemove": false,
    "networkMode": "host",
    "Binds": [
      "/opt/openvidu/recordings/:/recordings"
    ],
    "Ulimits": [
      {
        "Name": "core",
        "Soft": -1,
        "Hard": -1
      }
    ],
    "RestartPolicy": {
      "Name": "no"
    }
  }
}

The channel acts as if the rtmp signal never started, but if i send the same signal to Twitch for example it displays normal.

This are the medialive channel settings:

I would like to know if there are some possible causes to this or if i am configuring the service wrong, thank you.
