 I have an mp4 file that was pulled off a Flash Media Encoding Server that
 was post processed with f4vpp.exe and I am trying to do a straight codec
 copy to seperate the audio stream from the video stream and I can't seem
 to get it to work with newer builds of ffmpeg.

 I have an older build of ffmpeg (2008-09-24) that works but I want to use
 a newer build because I am unhappy with the quality of video that this
 build produces. Was looking for any advice on what might be the best way
 to do this:

 This command line:


 {{{
 d:\ffmpeg.NEW.exe -i d:\Testing\MovieConversionIssue\Issue.mp4
 -vcodec copy -an d:\Testing\MovieConversionIssue\videostream.mp4 2>
 d:\Testing\MovieConversionIssue\out.txt
 }}}

 Produces this output:
