KinesisVideoStream GetMedia gets stuck if gstreaming is pushing data simultaneously

### 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="" 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.
