Add Motion JPEG Video (MJPG) [ANSWERED]

Spongemak

@Monocle it should be possible to use HTTP and stream to RTSP, I tried to do it via VLC but you don’t support MJPEG Codec.

I don’t believe that Amazon/Alexa will support HTTP/S streaming. They only document support for RTSP and WebRTC.

I agree with you that Amazon should support HTTP/S MJPEG streaming, but last time I tested it, Alexa refused to stream it.

The Monocle gateway and servers do not touch the audio and video data, we do not re-encode or transcode anything as that would add too much latency.

PS: VLC will render HTTP/S streams because VLC supports HTTP streaming.

Thanks, Robert

@Monocle I’m using raspberry to stream my camera via RTSP buy it won’t work becase the lack of MJPEG Codec

raspivid -n - | cvlc -vvv http://192.168.68.152:8080/?action=stream:chroma=mjpg:width=640:height=480 --sout ‘#rtp{sdp=rtsp://raspberrypi.local:8554/}’

I have a RTSP stream with MJPEG but won’t work in echo, I dont know if it has something to do with your codec support or alexa.

Ok, tomorrow I’ll try to add the MJPEG option in the Web UI and you can test it. Apart from adding it to the camera configuration there is not much else we can do on our end. Alexa is a black box with respect to accepting and playing streams.

Thanks, Robert

@Monocle Thanks! I let you know if it works, Regards.

Will be interested to see if this works or not.

The MJPEG option is now available. After updating your camera feed and making the Alexa request, make sure to check your camera feed history in the Monocle web portals and make sure “MJPEG” is listed in the request data for the “videoCodec”:

Example:

    "timestamp": "2020-06-05T19:21:24.826Z",
    "request": "InitializeCameraStreams",
    "response": [
      {
        "uri": "...",
        "proxy": "...",
        "resolution": {
          "width": "320",
          "height": "240"
        },
        "authorizationType": "DIGEST",
------> "videoCodec": "MJPEG",
        "audioCodec": "NONE",
        "protocol": "RTSP"
      }
    ]
  },

Thanks, Robert

@Monocle I couldn’t get it to work, I think they better try converting the stream to H264, thanks a lot for the help anyway. regards.
