Video::Info::FOO - what is it useful for? an example list:
-video codec -audio codec -frame height -frame width -frame count
use Video::Info::FOO; my $video; $video->vcodec; #video codec $video->acodec; #audio codec ...
What does the module do? What are it's limitations? Is it built on top of other code? If so, what are the details and where can I get it?
Video::Info::FOO has one constructor, new(). It is called as: -file => $filename, #your RIFF file -headersize => $headersize #optional RIFF header size to parse Returns a Video::Info::FOO object if the file was opened successfully.
The Video::Info::FOO object to parses the file by method probe(). This does a series of sysread()s on the file to figure out what the properties are.
Now, call one (or more) of these methods to get the low-down on your file:

Audio codec name mapping is incomplete. If you know the name that corresponds to an audio codec ID that I don't, tell the Video::Info::Magic author, Allen Day <email@example.com>.
