 Could not open audio codec: Error number -22 occurred

 2. mp4 i get following error

 It seems like error is coming from avcodec_open2() in open_audio()

 Please let me know if i am missing something or i need to set something
 else to make it work

 How to reproduce:
 % muxing.exe test.mpg

 ffmpeg version

 built on Windows using MSVC 2012
