[Libav-user] Fwd: ffmpeg converted swf can't play audio in flash player

For 'versions on Apr, May and Jun of 2012 do not work', I mean I downloaded
executable, and run those executable directly with command line option "-i
For "ffmpeg at about May 2012 works" I mean our application uses ffmpeg
libraries compiled on code released at about May 2012. Our application uses
ffmpeg API to do conversion, and it works.
It failed on latest Zeranoe build, and today I also compiled on Ubuntu with
latest code, and converted swf still has problem.

This is very difficult to understand:
Above, you write that "versions on Apr, May and Jun of 2012"
do not work for you (iiuc).
Now, "ffmpeg at about May 2012" works fine.
Could you elaborate?
Or, even better: If you compile yourself, use git bisect to
find the change introducing the regression, if you are using
Zeranoe builds use http://ffmpeg.zeranoe.com/builds/win32/static/
to find the first version not working (and the last one working).
