Quick good or AVI/MPG file test??

Hey guys,

I just recovered a load of video files from a failed RAID array.
AVI mostly, but some MPG, MP4

A good chunk of them seem to be fine, but I have some that won't open and some that open but no video.

I'm hoping to find some kind of tool to run a quick and dirty test on them for now.
The equivalent of opening them in a player and closing them, you get the idea.

I have thousands of files so I don't want to go through a full check at this point.


I already wrote a program to loop through the files and log the results I just need the tool.
Command line utilities are fine.

I wrote the program to use with "AVIMaster" but the that utility is completely unreliable
It reports good files bad, bad files good.

Thanks,

Kenny
