I have 3 files: video.mp4, audionl.mp4 & audioeng.mp4.
I tried adding them all together in 1 output.mp4 file like this:
ffmpeg -y -i video.mp4 -i audionl.mp4 -i audioeng.mp4 -map 0:v -map 1:a -map 2:a -metadata:s:a:0 language=nl -metadata:s:a:0 title="NL" -metadata:s:a:1 language=eng -metadata:s:a:1 title="ENG" -acodec copy -bsf:a aac_adtstoasc -vcodec copy -movflags faststart output.mp4 2>&1
This is the output I see from ffmpeg:

So that looks fine.
But when I open it in VLC, I see under Audio tracks:

So I went back to check on ffmpeg with "ffmpeg -i output.mp4":

And here they are English again...
Afterwards I tried this:
ffmpeg -y -i audionl.mp4 -c:a copy -metadata:s:a:0 language=nl output.mp4
But also that failed to set the correct language on the output file...
I'm at a loss here and hope someone can help me set these languages correctly.
Thanks a lot!
FFmpeg expects ISO 639-2 codes for languages, so for Dutch, it's either
-metadata:s:a:0 language=dut
or
-metadata:s:a:0 language=nld

I have a file that was formed by concatenating three different files: a.mp4, b.mp4 and c.mp4.
do ffmpeg -f concat -i "concat-file.txt" -map 0:v -map 0:a -c:v libx264 -crf 23 -fflags +genpts joined-file.mp4"
After that I run this command, mentioned here: How to add a new audio (not mixing) into a video using ffmpeg?
ffmpeg -i joined-file.mp4 -i audio.mp3 -filter_complex "[0:a][1:a]amerge=inputs=2[a]" -map 0:v -map "[a]" -c:v copy -ac 2 -shortest output.mp4
What is causing this issue?
Thanks. :)
UPDATE:
Here are the commands that I have been running:
ffmpeg -i "middle/b.mp4" -c:v copy -video_track_timescale 30k -c:a aac -ac 6 -ar 44100 -shortest "wrap/b.mp4"
ffmpeg -f concat -i "concat-file.txt" -map 0:v -map 0:a -c:v libx264 -crf 23 -fflags +genpts "joined/abc.mp4"
ffmpeg -i "joined/abc.mp4" -i audio.mp3 -filter_complex "[0:a:0][1:a:0]amerge=inputs=2[a]" -map 0:v -map "[a]" -c:v copy -ac 2 -shortest "final/abc-cmplt.mp4"
Here is the "concat-file.txt":
file 'bits/a.mp4'
file 'wrap/b.mp4'
file 'bits/c.mp4'
All the video files a.mp4, b.mp4 and c.mp4 have their original audio. After I run the commands above, the joint video abc-cmplt.mp4 has combined audio (audio.mp3 plus their own) for the first (a.mp4) and last parts (c.mp4). However, the middle part only has its own audio and the extra audio I am trying to add does not seem to merge with the audio of b.mp4 in the final joint file.

All files to be concatenated by the concat demuxer must have these same attributes. b.mp4 has a different H.264 profile and lacks audio. Fix that:
ffmpeg -i "middle/b.mp4" -f lavfi -i anullsrc=cl=stereo:r=48000 -c:v libx264 -profile:v main -video_track_timescale 30k -shortest "wrap/b.mp4"
Then concatenate and mix the audio:
ffmpeg -f concat -i "concat-file.txt" -i audio.mp3 -c:v libx264 -crf 23 -filter_complex "[0:a:0][1:a:0]amerge=inputs=2" -ac 2 "joined/abc.mp4"
Option
Description
-f lavfi
Tell ffmpeg the following input is a filter instead of a file.
-i anullsrc=cl=stereo:r=48000
Use the anullsrc filter to generate silent stereo audio with 48000 sample rate.
-profile:v main
Set H.264 Profile to Main.
-video_track_timescale 30k
Set timescale to 30k to match the other videos (30k tbn).
I've read a number of other answers with similar problems, but they all have other variables/complications that (apparently) I don't understand, because I've had no luck in trying to apply them to the problem.
I'm trying to prepend a 10 second disclaimer video with no audio (created from a png file) to an MP4 video WITH audio, and am losing the audio altogether when I concatenate them.
What I'm doing is:
ffmpeg.exe -i MyDisclaimer.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts temp1.ts
ffmpeg.exe -i MyVideo.MP4 -c copy -bsf:v h264_mp4toannexb -f mpegts temp2.ts
ffmpeg.exe -i "concat:temp1.ts|temp2.ts" -c copy -bsf:a aac_adtstoasc "final.mp4"
Step 2 results in a .ts file that DOES have audio, but something in the 3rd step is ignoring/dropping the audio in the final output.
While creating MyVideo.MP4, I'm using -acodec copy to keep the original audio quality. How can I accomplish the same thing while concatenating, or at least stop losing it altogether?
Here's my output (with long paths removed), and the FFMpeg version is included at the bottom.
C:>ffmpeg.exe -i MyDisclaimer.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts temp1.ts

I am converting multiple mp4 video to ts and then stitching it together.
But this sometimes causes audio issues on my videos where the audio sounds like it was recorded with two mics at the same time causing loud sound.
I can only reproduce it sometimes and I am still not sure why it's doing that? Can anyone help?
Here is how I am converting to ts from mp4. I have noticed that the longer the video gets, the audio gets worse and its also off by a couple of seconds.
ffmpeg -i video1.mp4 -f lavfi -i anullsrc=channel_layout=mono:sample_rate=48000 -shortest -c copy -bsf:v h264_mp4toannexb -c:a aac video1.ts
ffmpeg -i video2.mp4 -f lavfi -i anullsrc=channel_layout=mono:sample_rate=48000 -shortest -c copy -bsf:v h264_mp4toannexb -c:a aac video2.ts
ffmpeg -i video3.mp4 -f lavfi -i anullsrc=channel_layout=mono:sample_rate=48000 -shortest -c copy -bsf:v h264_mp4toannexb -c:a aac video3.ts
and then I save these paths to a txt and call my stitching command like this
ffmpeg -f concat -safe 0 -i list.txt -c copy -bsf:a aac_adtstoasc finalvideo.mp4
Here is the complete output of the 4 videos

So I am certainly no expert when it comes to either of these tools, but I have a web-based project that's executing commands on an Amazon Linux server to concatenate two video files that are uploaded.
Both files are converted to mp4s first using FFMPEG, and those play perfectly in a browser after conversion:
ffmpeg -i file1.mpg -c:v libx264 -crf 22 -c:a aac -strict -2 -movflags faststart file2.mp4
Then, I attempt to combine these two resulting mp4s into a single mp4. I tried using FFMPEG to do this but to no avail. Switching to try MP4Box got me much closer: the videos are concatenated together, but the audio stops playing at the end of the first clip, and the second clip is silent.
MP4Box -force-cat -keepsys -add file.mp4 -cat file2.mp4 out.mp4
I've tried varying versions of the above command with no better results. Any input is greatly appreciated.

At least one output file must be specified
I have an ffmpeg that merges 3 mp4 videos and then another command that adds audio to the output file from the first command. The commands are as follows:
ffmpeg -i vid-1.mp4 -i vid-2.mp4 -i vid-3.mp4 -filter_complex "[0:v][1:v][2:v]concat=n=3:v=1" -preset ultrafast -crf 1 output.mp4
ffmpeg -i output.mp4 -i audio.mp3 -preset ultrafast -crf 1 final.mp4
vid-1.mp4 (does NOT have audio stream)
vid-2.mp4 (does NOT have audio stream)
Is there anyway to do this in one command? I would like to also add the audio to the video that is getting created in the first command. Is this possible?
Console output of "ffmpeg -i vid-1.mp4 -i vid-2.mp4 -i vid-3.mp4 -i audio.mp3"

I recommend to manually define mappings with -map instead of relying on the default stream selection behavior.
The -shortest option is added because the concatenated video duration is shorter than the audio duration.
