[vlc] Unable to transcode audio track to mp2

[Rett D. Walters]

Hello:

I am trying to use VLC to transcode a mpeg2 video file
that contains mpeg2 video and mp3 audio to a file that
contains the same mpeg2 video stream but with an mp2 audio
stream.  I am using the vlc gui to transcode the video
file, by selecting the file, and setting sout options to
PS file format, mp2a 192kbit, 2 channels. (Leaving the
video unselected).  I am unable to get VLC to generate the
stream.

Here is the error output of VLC when I try this:

[00000237] main input debug: set input option: sout to
#transcode{acodec=mp2a,ab=192,channels=2}
[00000237] main input debug: waiting for thread completion

instance, aborting
[00000237] main input debug: thread -1260684368 joined
(src/input/input.c:290)

Is it possible that I am missing a library that supports
mp2 encoding, or is there something else wrong?

I am using vlc-0.8.1 (Gentoo ebuild) using the recommended
gentoo use flags for vlc shown on the videolan.org
website.

Thanks,
