Ideal Interleaving setting for http streaming mp4

[UltraTV]

I'm in the process of developing an iphone app, and noticed that while youtube videos begin playback almost instantly, my own videos take nearly 20 seconds to load. I'm wondering if this could be do to the way I'm packaging my mp4's.

I usually just use the standard mp4box -add -add -new. Does anybody have any experience optimizing mp4 containers for this kind of thing? Much appreciated...

I am not sure how mp4box does it but some mp4 muxing programs put the metadata at the end of the file which would need a complete download of the file before the playback starts. If this is the problem then there are tools to fix it.

I use this one:

@UltraTV stay away from that apps: it corrupts subs&chapters in apple's style...

i never had any problems with mp4box muxing for apple's apps&devices...what is your exact command line?
