Unable to create still image from mp4 at ffmpeg

I am trying to create a still image (jpg) from mp4 file using ffmpeg of static in CentOS 7.2.
I remember using ffmpeg installed in yum before (I remember...), but I couldn't make it because of an error, so I brought a static ffmpeg.But it's a similar event.
I brought "-ss" in front of me because I want to make it at high speed.Below is the log of the execution and the contents of the error.If you know how to deal with it, please let me know.

$./ffmpeg-ss200-i/mnt/ram/enc/fb9f7f36627a684271c2b7154b6b3f10.mp4-vframes1-image2-s320x180/mnt/ram/enc/fb9f7f366271c2b7154b6b3f10.jpg

As far as the logs are concerned, the reason is that the mp4 file contains only audio data (mp4a format).
