Unsupported RTP media type

[fotosidla]

Hello

We have Vivotek Camera which produce livestream on this url:
rtsp://viewer:pass@123.123.123.123:554/live.sdp

I tried to use this url with or without port. But i am getting error
aws.iot.EdgeConnectorForKVS: stdout. 2023-12-13 20:39:09 WARN RecorderCameraRtsp:Unsupported RTP media type: application.. {scriptName=services.aws.iot.EdgeConnectorForKVS.lifecycle.Run.Script, serviceName=aws.iot.EdgeConnectorForKVS, currentState=RUNNING}

Ive installed gstreamer from offical site:

apt-get install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libgstreamer-plugins-bad1.0-dev gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-qt5 gstreamer1.0-pulseaudio

It seems that it should have plugin for sdp media type, but stream is not uploaded to kinesis.

I have all rights granted for kinesis stream, but i did not know what i should do with these errors.

Hi fotosidia,
Thanks for reaching out.
As far as I know, when the RTSP camera connects to the video recorder, it sends SDP, which contains the media types and other information of the camera, to the GStreamer rtspsrc element. Then, the GStreamer rtspsrc element creates GstPads based on the SDP information, and these GstPads also store their capabilities.
From our experience in developing this component, a RTSP camera reports SDP with media type video if it has video data and media type audio if it has audio data. Therefore, our component checks whether the media field is video or audio, and then processes these multimedia data accordingly.
The log of this issue shows that the camera gives us a GstPad with application media type, which our component does not support at the moment.
