--match-filter FILTER Generic video filter. Specify any key

(see the "OUTPUT TEMPLATE" for a list

of available keys) to match if the key
|

is present, !key to check if the key is
|

not present, key > NUMBER (like
|
||||
"comment_count > 12", also works with
|

>=, <, <=, !=, =) to compare against a
|
||||
number, key = 'LITERAL' (like "uploader
|
||||
= 'Mike Smith'", also works with !=) to
|

match against a string literal and & to
|
||||
require multiple matches. Values which
|
||||
are not known are excluded unless you
|
||||
put a question mark (?) after the
|
||||
operator. For example, to only match
|
||||
videos that have been liked more than
|
||||
100 times and disliked less than 50
|
||||
times (or the dislike functionality is
