MP4: Reorder audio tracks

schaggo · 15th November 2011, 00:26

Hi community

I really seem to fail here. I don't seem to be able to find the right tools or interpret tutorials and/or how-to's on their validity concerning my case. Everything seems to be understandably AVI-centric and somehow doesn't apply to MP4.

Ok, I got myself a nice Nero Recode-encoded MP4 collection. I'm not too good on those things but I believe they are AVC and I believe AAC, the Nero default in any case. All safely tugged in in my NAS. To complement my setup I recently got myself a nice network ready Philips-TV. It does read MP4, it only decodes the first audio track though. Unfortunately all my files are encoded the wrong way round. I'd like to switch the order of the audio tracks without having to recode everything.

Is this possible? MP4Box seems not to be able to do it on the go... Any help is highly appreciated here!

Oh, PS: Windows 7, 64bit...

Try the following command:
mp4box -add "source.mp4#1" -add "source.mp4#3" -add "source.mp4#2" "output.mp4"

Hmm... I recognise this command, I did use it. But somehow it didn't lead to the desired results. I will try again and report back, maybe I did something wrong back then.

Thanks for your answer! Highly appreciated.

My input is somehow borked, although the -info output doesn't mention anything while the -add operation fails immediately after execution. Here we go:

Code:

mp4box -info source.mp4
