Due to converting from flv to mp3 ffmpeg runs out with error

[Maxroy]

Hi!
I use webinars service in the internet and they save webinars in adobe air file format. And after that I dowloading webinar record and simply install it onto my workstation (MS Windows Vista sp2). My due is to convert from flv-format to mp3 so i could publish it on a website.

Recently I found that my ffmpeg.exe when it converts flv file to mp3 format it runs out with error (see below).
Earlier everything was OK. but now I got a problem.

Could anybody tell me what's the matter of this mistake?
any help would be

I would try another ffmpeg build, see http://ffmpeg.arrozcru.org/autobuilds/

Or check http://www.experts-exchange.com/OS/Linux/A_2592-Fixing-output-buffer-too-small-issue-f...ibmp3lame.html

Ok. this decision was useful for some flv files, but some of them are still convert with mistakes, such as:
