Sorry about not pasting the log, thought that the one of ffprobe was enough
to understand the problem...

So the problem are the default values for probesize and analyzeduration.

probesize defaults to 500k, analyze duration to 5 secs. I think I can
easily raise those values in my pipeline without big size effects, except
for a small delay...

but, also when the decoder find the format hints it needs, it seems that
the file misses something:

shelob-2 $ ./ffmpeg -analyzeduration 2000000000 -probesize 25000000 -i

... so I'm still worrying if the source file is correct (I do not like all
those missing picture parameter set references). We are gonna receive a lot
of similar files from a (paid) video supplier, so if the format is somewhat
broken I have to make them fix it.

remove it, it's a stupid company policy.
