multiplex aac and mp4..

[hk]

Hi,
I got a aac file (~18MB) and a mp4 file (~175MB, created with DivX5pro´s Mp4 creator).
So I tried to multiplex both files using the command
mp4creator60 -rate=25 -I -c=audio.aac video.mp4

and got the message:
MP4 error: Mp4 Array :: (): Result too large

but there is plenty of hd space!!
Any ideas? Your help is appreciated,
HKA

Don't bother using DivX 5 Pro's mp4 maker, it stinks, use the same tool you are using for the audio (mp4creator60) to convert the avi into the mp4, then you can add the audio using mp4creator60 again. Example:

mp4creator60 video.avi example.mp4
mp4creator60 -I audio.aac example.mp4

The "-I" tells mp4creator to interleave the audio. If you want to stream your mp4, remember to use "-H" in both cases. The "-O" flag for optimizing hasn't really been necessary, Darwin Streaming Server doesn't need it (at least according to Apple's docs).

Make sure you are using a recent version of mp4creator, like 0.9.5.1, for best results.

Hi T-S,
thanks for the reply > the multiplexing did work. So far so good, but
playback with the wm4player 0951 did not work. Message:
WMP4CLIENT causes an error because of a incorrect page in Modul MSVCRT.DLL at 015f:78011b09.

(I translated the german part,HK)

So any ideas regarding this matter? There should be a new player (0952-Version) but where? Greetings,

The wmp4player is buggy, and fixing it is not a priority right now for the mpeg4ip guys. Try the EnvivioTV mp4 plugin from http://www.envivio.com - it works quite well with RealONE and Windows Media player. It does not support b-frames or 5.1 audio.

Hi tanksompson,
thanks for the tipp reg. envivio. It works, except that sound and video
are asynchronous.
I set the audiodelay in AACmachine accordingly the value DVD2avi gave me first when extracting the AC3. But when I muxed the AAC and the mp4, I did not had the option to set the delay (like it´s possible in NanDub when interleaving MP3 and DivXavi). So I guess thats why it´s asynchron. Do you know a way out of this?

Try to use besweets OTA feature to delay the transcoded audio file itself.
e.g. if audio is 80ms delayed use -ota( -d 80 )

but maybe AACmachine set the delay properly and envivo has sync problems..

Hi Zulu,
i tried it again today (with setting AACmachines delay option) and this time it worked. So all is nice and shiny...
at least so far.
