 This issue can be reproduced on both latest Zeranoe build and Linux build.

 I used ffmpeg command: ffmpeg.exe -i input.mp4 out.swf to convert a mp4
 file into a swf file.

 Then the generated swf file when played in Adobe flash player, couldn't
 stream audio. But the same file can stream audio correctly when played in
 VLC player.

 I tried different versions of Zeranoe build and found that the first
 version that has this issue is ffmpeg-git-1eabd71-win32-static, which was
 release in 07 May 2012.
