how to creating Quicktime Player v7.xx compatible 6 channel aac + x264 in mp4 file?

I'm used to convert trailers from various formats to x264+aac. These are working well when we speaking about 2 channel audio (CE-QuickTime profile in megui), but not with 6ch. (Before you asked why QT7 compatible files: lots of users are demanded it. :( ) Strange is that when I have created a 6ch *.aac (with CT) it plays fine in QT7, but if it's in an mp4 container, it doesn't. (So probably the mp4 parser of QT7 is bad.) The bad thing is that I can't remux the encoded video and audio into a mov container. (Maybe QTInput avisynth plugin can do this, but I think it doesn't support 6ch audio in QToutput ... :( ) So does anyone manage to do this? Thanks

If I am not mistaken Quicktime simply doesn't support 6ch in mp4. You can search a bit and you'll find some threads were it is mentioned.

exactly, quicktime simply su*s

Quicktime does sucks but pretty much every HD trailer in the Quicktime site has 6ch AAC. The tricky part is to get into an compatible MP4 container.

again, my qt doesnt support 6ch aac in mp4, be it mpeg-4 or mpeg-2 if you have a working sample i would be happy if you could upload it somewhere btw mp4box will signal the aac as mpeg-4 or mpeg-2 depending on whether mpeg-2 or mpeg-4 is signalled in the raw .aac

is 6 channel aac in mp4 that works fine for me in QuickTime. And I knew that mp4box would set mpeg2 or mpeg4 based on the .aac; I just thought there was a way to force one or the other.

It doesnt play on QT 7.1.3 for windows... tried on 3 PCs...

i tried a 6ch aac mov and it works here. seems damn apple limits it in mp4 only on windows...

Not quite related, but found this in another thread: it shows how "good" the Quicktime h264 decoder is (tests made on Windows)... . Which makes me wonder why do people really care about Quicktime on Windows at all...

1. QuickTime sucks (mov is "nice" but thats a different part) 2. Apple will fix this in the next days or weeks cause of if they don't change they are not longer allowed to say "quicktime supports ISO / ISMA MPEG-4" and this apple dont want ... loss of money/customers. But to fix this problem ourself, just totally ignore QuickTime and perhaps make your files inreadable by Quicktime (just change a bit in the mp4-container). If we start ignoring Apple/QT, they'll stop ignoring us! Sorry for my "english"
