ffmpeg:audio:add_an_audio_file_to_a_video_overwriting_existing_audio
ffmpeg - Audio - Add an audio file to a video, overwriting existing audio
ffmpeg -i inputvideo.mp4 -i audiotoadd.mp3 -map 0:v -map 1:a -c:v copy -shortest outputvideo.mp4
NOTE: Overwrite any existing audio on the video inputvideo.mp4 and replace it with audiotoadd.mp3.
- Stream 0 which is the first input is mapped as the video stream.
- Stream 1 the second input becomes the audio input.
The video stream is copied (not changed) and by using the -shortest command, the encoding ends when the shortest input stream ends.
- Meaning there will be no audio without video or video with no audio in the output.
