    16  is basically equivalent to:
    17 {{{
    18   ffmpeg -i INPUT -map single_highest_quality_video_stream -map single_highest_quality_audio_stream OUTPUT
    19 }}}
    20 and OUTPUT will receive those two streams.  All other streams are discarded.  When you want to control which stream is included, or include more than one stream in the output, then you will need/want to specify the "-map" command manually.
     16is to, in essence, discover the "highest quality" (single) video input stream and "highest quality" (single) audio input stream from all input(s), and "send" that to the OUTPUT.  All other input streams are in essence discarded.

    2218The "map" command basically means "include this stream into the immediately following OUTPUT file."

     20If we wanted to "show" the same behavior using the map command, it would look like this:
     21
     22{{{
     23  ffmpeg -i INPUT -map single_highest_quality_video_stream_from_all_inputs -map single_highest_quality_audio_stream_from_all_inputs OUTPUT
     24}}}
     25and OUTPUT will end up with 2 streams, one audio, one video.
     26
     27When you want to control which streams are included, or include more than one stream in the output, then you will need/want to specify the "-map" command manually, and change these parameters.
