How to create an empty mp4 (without mp4ui)

[JoeBG]

Hi,

hope noone kills me for this question :)
But I need a commandline possibility to create an empty mp4 with mp4creator or mp4box. mp4ui can do this, so there must be a commandline for mp4creator for this, but I can´t find it :( .
I just need a little tip pleas :)

I don't know that there is a direct way to do this. AFAIK mp4ui incorporates the source for mp4creator and as such isn't limited to the command line options. You can use a short track to create the MP4 and then delete the track i.e.

mp4creator -create dummy.aac empty.mp4
mp4creator -delete=1 empty.mp4

Works great, many thanks :)

of course this creates the .mp4 fitting the aac, a stream which than gets simply deleted, so its not really an empty .mp4

JoeBG, why do you need such an empty mp4 btw?

:D For the new mp4muxer coming from movie2digital. He can mux everything, AAC in mp4, ASP in mp4, AVC in mp4, AAC, mp3, AVC in AVI, Xvid or Divx in AVI, srt and ttxt. You just add the mp4, avi, srt or raw stream. He muxes everything in an existing mp4 without changing the content of the container (Chapters, menues, all you want)or streams. If you don´t add a mp4, he (now :) ) creates a empty mp4 and muxes everything in this new empty one. The basic idea was, to start the encoder and building a chapter.mp4 while the encoder is working
:D - but now you can use this option for everything or do not use it.

You can do basics: just adding one avi and one mp4 with aac or you can do more complex things like one or two mp4 with aac, mp3, subs, a chapter mp4. one AVC video in avi or in mp4 :) Hope you all will like it.

Coming before weekend (latest tomorrow).

It´s totally empty because dummy.aac is not existing and don´t needs to get deletet. mp4creator really creates just a empty mp4 - very good for the new muxer.

In the video field you can add everything, but no ASP.mp4 (but you can add it in the mp4 field :) ). I don´t have a solution for this (http://forum.doom9.org/showthread.php?s=&threadid=89595) problem.

I´ll make an extra threat for mp4muxer tomorrow, now it´s time for bed :)
