[FFmpeg-user] Play Camera RTSP H264 Stream

I'm trying to view a H264 stream from an Avigilon camera which has the option
to create a RTSP stream.  I can view the stream succesfully n VLC so it
seems as though the stream is correct?  However, when I try to view it in
ffplay or transcode it in ffmpeg I repeatedly get the PPS errors below
followed by a conversion error and no video.  Anyone know what the issue is
or have a suggestion?
