Adding 2 audio streams to a video

[Jawz22]

Hi, I have recently been trying to improve my knowledge using FFmpeg and have been playing around with adding more than one audio stream to a video. I successfully managed to add two different English audio streams to my video, 6-channel, and 2-channel. I'm wondering if there is a way to name the channels something like English 6 channel and English 2 channel?

Command Line I'm using:

ffmpeg -i v_dec.mp4 -i a_dec.mp4 -i a1_dec.mp4 -map 0 -map 1 -map 2 -metadata:s:a:0 language=eng -metadata:s:a:1 language=eng -c copy final.mp4

Not tested but try:

ffmpeg -i v_dec.mp4 -i a_dec.mp4 -i a1_dec.mp4 -map 0 -map 1 -map 2 -metadata:s:a:0 title="EN6ch" -metadata:s:a:1 title="EN2ch" -c copy final.mp4

ffmpeg -i v_dec.mp4 -i a_dec.mp4 -i a1_dec.mp4 -map 0 -map 1 -map 2 -metadata:s:a:0 title="EN6ch" -metadata:s:a:1 title="EN2ch" -c copy final.mp4

Thank you, this worked a treat. With Quotation marks, you can name them anything you like. So I named them English 6-Channel and English 2-Channel.

@codehound was wondering if you could help me combine these 2 command lines into one.

This one I'm using this like the above to name the two sound channels:

ffmpeg -i v_dec.mp4 -i a_dec.mp4 -i a1_dec.mp4 -map 0 -map 1 -map 2 -metadata:s:a:0 title="[English 6-Channel]" -metadata:s:a:1 title="[English 2-Channel]" -c copy final.mp4

and this one I'm using to add subtitles to the mp4 video and also name the language of the subtitles:

ffmpeg.exe -i final.mp4 -sub_charenc ISO-8859-1 -i a.vtt -map 0:v -map 0:a -map 1 -c:v copy -c:a copy -c:s mov_text -metadata:s:s:0 language=eng New.mp4

I want to combine them if possible because when I run them one after another, the naming of audio channels is taken over by the naming of the subtitles when I run the second command. So my sound channels are no longer named as I wanted.

Thanks

If you're fine with mkv format, mkvtoolnix has option to name tracks whatever way you want.

Thanks, I'm aware of mkvtoolnix, nice program. But ideally want to keep the files to mp4.

Cheers

Use clever FFmpeg-GUI.
Portable, no installation, small.
You can simply add the audiostreams you want and edit/change/insert the language, and stream title tag, the delay and the default tag.

Thank you very much, great work on the GUI
