KinesisVideoStream GetMedia gets stuck if gstreaming is pushing data simultaneously #2203
Description
Describe the bug
I am finding that both GetMediaAsync as well as GetMedia get blocked if I am simultaneously running gstreamer plugin to push the media from the camera. It works fine if I stop the gstreamer session.
Here is the stack where it is stuck:

Expected Behavior
The GetMedia call should return successfully and return the Stream.
Current Behavior
API gets blocked.
Reproduction Steps
-
Run the gstreamer command to push the media to the kinesis video stream. The command line that I am using is:
gst-launch-1.0 v4l2src do-timestamp=TRUE device=/dev/video0 ! image/jpeg ! jpegdec ! x264enc tune=zerolatency ! h264parse ! video/x-h264,stream-format=avc,alignment=au ! kvssink stream-name="<stream_name>" storage-size=512 access-key="" secret-key="" aws-region="us-west-2" -
Run a sample to get call the GetMediaAsync or GetMedia.
The call will not return until the gstreamer session is canceled.
