What software can remove an audio stream from an mp4 file?

[LeetPirate]

Hey guys, I'd like to hear about any software you guys use to strip unwanted audio streams from mp4 or m4v files. The problem is sometimes I have files with multiple audio tracks and I only need one. I want to just delete unwanted audio streams and repack the streams I want into the mp4 container without doing any encoding. I came across this app called MP4Box which looks like it can get the job done but I wanted to your opinions about MP4Box or any alternatives you may know about.

FFMPEG maybe?

First run

ffmpeg -i file.mp4

to see which streams exists in your file. You should see something like this:

Stream #0.0: Video: mpeg4, yuv420p, 720x304 [PAR 1:1 DAR 45:19], 23.98 tbr, 23.98 tbn, 23.98 tbc

Stream #0.1: Audio: ac3, 48000 Hz, 5.1, s16, 384 kb/s

Stream #0.2: Audio: ac3, 48000 Hz, 5.1, s16, 384 kb/s

Then run

ffmpeg -map 0:0 -map 0:2 -acodec copy -vcodec copy -i file.mp4 new_file.mp4

to copy video stream and 2nd audio stream to

new_file.mp4

See if this helps --- tsmuxer , http://www.videohelp.com/tools/tsMuxeR

Simply drop in the mp4 file and hit on demux .

What it will does is , it will break down the media file into individual Audio and Video files .

Simply get the Audio file you want and convert it into any format you desire .

tsmuxer is great for encoding any file into Blu ray format ( m2ts , mts ) so that it is easily played on the Blu ray players .

Helps me in this , when i found this side function of demuxing , where i use it to get mp3 of some rare songs via videos downloaded from Youtube .

You are on the good way.

You have to use a Multiplexer/Demultiplexer. Like MP4Box. Like other members proposed.

Here you are a great site for this kind of stuff : http://www.videohelp.com

If you go on the Video De/Multiplexers section, you have a lot of tools, like "My MP4Box GUI" which is a GUI for MP4Box.

Cheers.

You'll be doing great using MP4Box :) , if you don't like it,try tsmuxer,both of them are easy to understand/use :showoff:

Thanks for the information guys

Thank you for the many informative replies. I am a long time visitor of videohelp.com, since the days of tweaking Hanks encoder to build dvd until ConvertXtoDVD came and saved me tons of time. :D

I looked at txmuxer which is a solid app I have used to create AVCHD discs in the past. I will sift through the list of Video De/Multiplexers but I think I am comfortable with the 3 suggestions here, ofcourse I prefer gui so I will try Mp4Box GUI and tsmuxer and if the results are not satisfactory then cmd line ffmpeg is last resort.
