nal-hrd help a little incomplete

[jpsdr]

In the nal-hrd help :

--nal-hrd <string> Signal HRD information (requires vbv-bufsize)
- none, vbr, cbr (cbr not allowed in .mp4)

The default setting is not specified.

[Trahald]

Nalhrd is not on by default (it's wasteful if you don't need it) so there is no default setting

[jpsdr]

In that case, default setting is "none". Each time a command has parameters, and is not just an ON/OFF commande,
help tells the default setting. According the help format of the others settings, it should display something like this

--nal-hrd <string> Signal HRD information (requires vbv-bufsize) ["none"]
- none, vbr, cbr (cbr not allowed in .mp4)

[Trahald]

Then ask for the 'none' to be removed. see --pass

[jpsdr]

I ask nothing, i personnaly know that's it's disabled by default.
I just wanted to notify something wich i thought was not correct.
I've notify, now, if after your said it's normal, fine for me.
