-====== ffmpeg - Audio - Adding audio to a video file ======
-Adding an audio file to a video is achieved with mapping.
-  * Video files can contain more than just a video and audio stream, they can have multiple audio streams for different language as well as subtitle files.
-  * Mapping for a video stream also contains the different quality and bitrate options.
-----
-===== Example =====
-<code bash>
-ffmpeg -i video.mp4 -i audio.mp3 -c copy -map 0:v:0 -map 1:a:0 output.mp4
-</code>
-<WRAP info>
-**NOTE:**  This maps the video to the first video stream of the output (default) and the audio onto the first audio stream in the output file.
-  * This command copies the two files into one without any compressing;
-  * If one file is longer than the other use **-shortest** which finishes the encoding when the shortest stream ends.
