There's audio/mp3_check which accepts an arbitrary number of files (ie: you 
can wrap it in find+xargs). 
I'm not sure how much time this may cost though.

As for video: this entirely depends on the format and what 'corrupted' means 
exactly. A corrupted header might be easy to find, but other than that, most 
(if not all) video formats allow for arbitrary lengths, which means that each 
frame has it's own checksum or equivalent.
