[FFmpeg-user] Verify integrity of a video file?

I want to verify (on Win 7) the integrity of a video file (e.g. *.avi or *.mp4 or *.mkv)
Therefore I enter according to some suggestions:
ffmpeg -i videofile.avi -f null -
This seems to work. However a lot of "normal" stuff is outputted as well.
I only want an output message in case of error.
As far as I read the "-v error" should do the trick:
ffmpeg -v error -i videofile.avi -f null -
but this yields absolutely NEVER an output (even if I verify a non-video *.png or *.log file).
So how else can I get only-a-short-error-message-in-case-of error?
Just a second question:
Is it possible to verify with ONE ffmpeg command all *.avi/video files in a directory tree?
Something like that:
ffmpeg -i:recursivedir D:\videos\*.avi -f null -
or do I have to search for all videofiles in dir tree beforehand and enter the command for each file separately?
