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).

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

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

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
