[FFmpeg-user] Is there a way to determine the level of compression

I most of the time use:
    -vcodec libx264 -crf 26

Depending on the video this works great. Often the new size is between
1/6 and 1/14 of the original file. But in certain situation the size
of the new file increases. In those cases I could better use copy. Is
much faster and creates a smaller video. Is there a way to determine
the crf value of a video? Then I could use that to determine if I
should use copy, or not.
