How to multiplex avi files on linux/mac/windows? (command line)

[Selur]

I got an Xvid video (5hrs+ ~4.5GB)
Multiple audio streams with negative delays.
I want to multiplex them.

Goal: find a command line tool which allows to use multiple delays

Problem is:
a. mencoder only supports multiplexing only a single audio stream afaik. (using '-audiofile' can't be used multiple times)
b. ffmpeg can't handle negative delays with multiple audio streams (https://trac.ffmpeg.org/ticket/1349)

My current workaround is to use ffmpeg and cut the audio using delaycut before multiplexing, but I'm wondering is there a cross platform tool which can do what ffmpeg&mencoder can't ?

Should do the same as delaycut with negative delays, shouldn't it?

[Selur]

Probably. I usually use delaycut to remove all delays when when I remove the negative delays.
But I would like to avoid cutting the audio.

But removing negative delays is cutting audio?

With positive delays I only see: 1. encode silence 2. cat

still would be nice to at least do this in one call and not process each audio on it's own
