[FFmpeg-user] ffplay and a cctv file

Hi,

I have a cctv data file (h264, I think) and when I try to play it with
ffplay the bottom half of the video is corrupted. Is there some command
line options which will enable playing if?

I have attached a screenshot and uploaded a 1MB sample to
https://www.dropbox.com/s/8n8s40mz5zrw7jj/cctv.sample?dl=0

Thank you,

John
