No the format is:
 DE name      description

D = decoding supported
E = encoding supported
name = unique name for the format
description = human readable description

The name has nothing to do with the extensions, also the extension
doesn't detect the format in a file reliably (you should probe for
that). But some formats are bound to some extensions, and this
information can be retrieved in the AVInputFormat/AVOutputFormat
public struct, so you could write a simple program for listing that

(BTW this is a user-related question, so it is off-topic in this
development-only mailing list).
