Hi all,
     I play RTSP stream with ffplay, then complain that 
>  [swscaler @ 0x7f94a834e400] deprecated pixel format used, make sure you did set range correctly

    After that, I try with the command `ffplay rtsp://a:a@ -pix_fmt yuvj422p`, error log:
>  Option -pix_fmt is deprecated, use -pixel_format.
    Following the tips, it’s still not ok.
>  Option pixel_format not found.
   What should I do to solve the issue?
