Dear Mark,
Thank you for your reply. But I'm looking at the syntax of Stream
specifiers. It clearly specifies 7 forms.
1. stream_index
2. stream_type[:additional_stream_specifier]
3. g:group_specifier[:additional_stream_specifier]
4. p:program_id[:additional_stream_specifier]
5. #

Please write your replies *below* the quoted text that you refer to,
not above. That makes it easier to follow the thread of conversation
in chronological order, and it reduces the risk of misquotes.

Thank you so much for the detailed explanation. That clarified a lot!
I then searched Google for the map syntax you provided, and it turns
out to be from the `--help` option of ffmpeg.
I had always believed the help information was available online. Now I
know I have to read `ffmpeg --help`.
