I think i may have found a regression or at least a difference: on my
laptop, avplay open the stream without any problem. On my desktop, it
hangs forever and i can make it works using the -probesize option (as
in my code).
my laptop runs a debian testing with a mix of debian and
debian-multimedia repositories. My desktop runs a debian testing with
only debian repository.
on the desktop, avplay says :
avplay version 11_beta1-6:11~beta1-2, Copyright (c) 2003-2014 the Libav
developers

on the laptop:
ffplay version 2.3.3 Copyright (c) 2003-2014 the FFmpeg developers

so i suppose that debian-multimedia is using ffmpeg instead of libav
(but it needs to be checked). If i install libav-tools from debian repo
on my laptop, it hangs, like the desktop
