-acodec copy does not copy wav file correctly (at least with with pcm_s24le )

[NabilStendardo]

What we have:

An audio file encoded in wav pcm_s24le(let us call it a.wav) from the output of a previous ffmpeg command.

What we want:
To execute:

$ffmpeg -i a.wav -acodec copy b.wav

and have an identical (and valid) wav file.

What we get with cmp:

$cmp -b a.wav b.wav

a.wav b.wav differ: byte 39, line 1 is 30 ^{X 0} @

Of course 30 is octal for 24, which is the expected value from the first file (bits per sample). 0 here is clearly wrong. Note that b.wav does not play under gstreamer (which is somewhat normal because it is AFACT invalid)

Please add the complete, uncut output of your ffmpeg command.
