 > Are you sure that the avi header explicitely contains the delay?

 Well, not quite sure (may be it's a defective video), but 2 symptoms point
 to it:

 1- When processed through ffmpeg, audio rewinds 2.5 seconds back from its
 correct position.

 2- Incidentally ''Media Player Classic'' also informs about a 2.5 seconds
 delay. Please see this capture: [https://i.stack.imgur.com/bl7CI.png]
 These is the delay I expected '''ffprobe''' to inform me.

 > The conversion needs {{{-async 1}}}

 Thanks for the tip, I will test it.
