MP4 Muxer that Supports Audio Delay Functions

[ScootyPuffJr]

Hello Everyone.

I'm trying to mux some x264 encoded video with NeroAAC encoded audio. I've been using mp4box successfully for a while, but now I've come acrsoss some content that I need to adjust the audio delay for, and the mp4box audio delay features don't work. Can someone suggest a free alternative muxer that supports audio delay?

Thanks,
SPJ

The other full-featured free muxer is mp4creator. I have no idea if it supports delay though.

mp4box can set the delay. the question is whether the demuxer/player you are using is supporting it

So setting the delay doesn't physically mux the tracks slightly off? It justs adds a paramater that the players are supposed to honor?

I'm using Apple's Quicktime Player / an iPod to view the contnet, so apparantly it doesn't honor the delay setting.

At this point I assume my option is to re-encode using AVISynth and adjust the delay at that point, or physically add/remove a delay to the aac file then?

Thanks!
