Comment:

 ͏    Effective:
 ͏    `"select='eq( n, 0 ) + not( mod( t, 10 ) )'"`

 ͏    See also:
 ͏    https://ffmpeg.org/ffmpeg-filters.html#select

 ͏    Documentation too vague: unable to tell exact meaning.
 ͏    But likely the example is misuse: "expr" seems to expect something
 like boolean, mostly.
 ͏    (but with strange implementation to handle sort of eerie stream
 mapping...)
