Kinesia kvs_gstreamer_sample error: Failed to un-pause curl

I followed the tutorial made by Paul Shiner on Youtube for IoT streaming of RTSP to Kinesia.

I am using the command

./kvs_gstreamer_sample camera_inhouse rtsp://<<username>>:<<password>>@192.111.1.96:554/

But I keep getting into the error

Bus error

The stream does run succesfully as I have tested it using VLC.
I've tried some experimentation by editing the streaming format of the RTSP camera (such as changing the frame rate) but to no avail.

As I understand putKinesisVideoEventMetadata() thows the error because it senses that the stream is not running.

I figure the error is due to the notifyDataAvailable() being unable to un-pause the curl command.
But I have no idea what is causing the issue with un-pause and how to resolve it.
