Comment (by Sami32):

 Thanks, {{{-f ipod}}} do include the audio stream, but it is not
 streamable by default as {{{-f m4v}}} can be for a pipe output. Adding
 {{{-movflags}}} with the correct parameters do the job though, but it make
 the command line longer ;-)

 That mean that i misunderstood M4V format, because i thought that it could
 contains audio stream.
 But it seem that you said that it cannot, so i will try to remember it.
