I used a command like:
ffmpeg -i video.avi -i audio.mp3 -vcodec codec -acodec codec output_video.avi -newaudio
in latest version for adding new audio track to video (not mix).
But I updated the ffmpeg to the newest version (ffmpeg version git-2012-06-16-809d71d) and now in this version the parameter -newaudio
doesn't work.
Tell me please how I can add new audio to my video (not mix) using ffmpeg
.
If you are using an old version of FFMPEG and you cant upgrade you can do the following:
ffmpeg -i PATH/VIDEO_FILE_NAME.mp4 -i PATH/AUDIO_FILE_NAME.mp3 -vcodec copy -shortest DESTINATION_PATH/NEW_VIDEO_FILE_NAME.mp4
Notice that I used -vcodec
mp3 music to wav
ffmpeg -i music.mp3 music.wav
truncate to fit video
ffmpeg -i music.wav -ss 0 -t 37 musicshort.wav
mix music and video
ffmpeg -i musicshort.wav -i movie.avi final_video.avi
Code to add audio to video using ffmpeg.
If audio length is greater than video length it will cut the audio to video length. If you want full audio in video remove -shortest from the cmd.
String[] cmd = new String[]{"-i", selectedVideoPath,"-i",audiopath,"-map","1:a","-map","0:v","-codec","copy", ,outputFile.getPath()};
private void execFFmpegBinaryShortest(final String[] command) {
final File outputFile = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/videoaudiomerger/"+"Vid"+"output"+i1+".mp4");
String[] cmd = new String[]{"-i", selectedVideoPath,"-i",audiopath,"-map","1:a","-map","0:v","-codec","copy","-shortest",outputFile.getPath()};
try {
ffmpeg.execute(cmd, new ExecuteBinaryResponseHandler() {
@Override
public void onFailure(String s) {
System.out.println("on failure----"+s);
}
@Override
public void onSuccess(String s) {
System.out.println("on success-----"+s);
}
@Override
public void onProgress(String s) {
//Log.d(TAG, "Started command : ffmpeg "+command);
System.out.println("Started---"+s);
}
@Override
public void onStart() {
//Log.d(TAG, "Started command : ffmpeg " + command);
System.out.println("Start----");
}
@Override
public void onFinish() {
System.out.println("Finish-----");
}
});
} catch (FFmpegCommandAlreadyRunningException e) {
// do nothing for now
System.out.println("exceptio :::"+e.getMessage());
}
}
Nothing quite worked for me (I think it was because my input .mp4 video didn't had any audio) so I found this worked for me:
ffmpeg -i input_video.mp4 -i balipraiavid.wav -map 0:v:0 -map 1:a:0 output.mp4
If the input video has multiple audio tracks and you need to add one more then use the following command:
ffmpeg -i input_video_with_audio.avi -i new_audio.ac3 -map 0 -map 1 -codec copy output_video.avi
-map 0
means to copy (include) all streams from the first input file (input_video_with_audio.avi
) and -map 1
means to include all streams (in this case one) from the second input file (new_audio.ac3
).
None of these solutions quite worked for me. My original audio was being overwritten, or I was getting an error like "failed to map memory" with the more complex 'amerge' example. It seems I needed -filter_complex amix.
ffmpeg -i videowithaudioyouwanttokeep.mp4 -i audiotooverlay.mp3 -vcodec copy -filter_complex amix -map 0:v -map 0:a -map 1:a -shortest -b:a 144k out.mkv
