amazon-kinesis-video-streams-producer-sdk-cpp: Internal data stream error when streaming from RTSP source.

I’m using the producer library in a Docker container to stream from RTSP source. The RTSP source is Amcrest cameras (model # AMNV20M8-4B-B).

I’m using the following startup script to trigger the stream.

#!/bin/bash

AWS_ACCESS_KEY_ID=$1 AWS_SECRET_ACCESS_KEY=$2 AWS_DEFAULT_REGION="us-east-1" gst-launch-1.0 rtspsrc location=rtsp://$3 short-header=TRUE ! rtph264depay ! video/x-h264, format=avc,alignment=au ! kvssink stream-name=$4 storage-size=512

There are 2 issues. It tries to receive UDP packets for 5 seconds and then switches to TCP. On my Mac, I have switched off firewall to ensure that’s not a problem.

After it switches to TCP it gives warnings about could not transform video/x-h264 and eventually fails with internal data stream error.

Below are the logs after the pipeline starts playing.
