Gstreamer RTSP Docs Update

Hoping this help others avoid hours of frustration.

As noted in the helpful but well hidden issue comment awslabs#193 (comment), the Gstreamer examples for RTSP do not run at all.  I'm no Gstreamer expert but using `h264parse` works perfectly, while `video/x-h264, format=avc,alignment=au` just causes the pipeline to hang.
