Are there any (free) tools to mux (insert) audio w/out create new file ?

[vhelp]

First, I appoligies if this has been asked before.

* looking for freeware tools for this function

Ok. So a few days ago, I did some searching around for a transcoder that can take an audio file and *insert* it into an already encoded MPEG-2 file.

Often times, whenever I am capturing/editing/encoding, I dont' have the luxury of including the audio during the mpeg encoding phase. For instance, sometimes I an avisynth script w/ no audio during encoding, and sometimes its just the nature or order of things I'm doing at the time. Re-encoding is almost certainly out of the question. But the missing audio aspects is usually because I'm editing the video via a script and either forget to consider the audio or can't (because of the unique circumstance) but in some cases, I can sneak in the audio (later) using the same position of the avs script and the virtualdub .vdr (which has the audio) and then mux a separate audio ( *.mp2 ) from it. Then, I using MPEG Tools in tmpgenc, I will multiplex the A/V into a new MPEG-2 source.

The problem with the above is that it creates a second source file. I am often very low on HDD space during these pressing times. So, having searched around for the right tool, I haven't been able to find one that can do the job need--to mux (insert, without intermediate file creation) the audio into the existing .mpg file.

I did try ffmpeg, (hoping that it muxes w/ insertion in mind) but even though it seemed to work, (though creating a new file) there was no sound to be heard--very frustrating.

--> ffmpeg -i file.mpg -vcodec copy -i audio.mp2 copy -ar 48000 -ab 384 -ac 2 -y new_mpeg.mpg

So, my question is:

Are there any tools that can insert audio (mp2 or ac3) into an existing .mpg file without creating a 2nd or new source file ?

Thanks,

You could try ImagoMPEG-Muxer or maybe tsMuxeR. I've never used the first one and tsMuxeR may be overkill.

There is no such tool. Why don't create video only file in .m2v / .mpv format, and then mux it with audio?
