Hi, wma exists in a few different formats, those formats doesn't really
correlate well
to what microsoft is naming it. What you are asking about is wma
standard. Ffmpeg
can handle all wma standard files. Microsoft name it wma9 coz it is
bundled with
their version 9 of the player. There is a wmapro codec that currently
can't be decoded
with ffmpeg. The easy way to know what format you are dealing with is to
the id number. 0x161 should always be wma standard.
