Output File Patterns:
-
The -o argument specifies the name of the file(s) to write to. If the
argument does not include any escape characters, the output will be
written to a single file. Otherwise, the filename will be calculated by
expanding the following escape characters:
- %w
-
- Frame width
- %h
-
- Frame height
-
%<n> - Frame number, zero padded to <n> places (1..9)
-
Pattern arguments are only supported in conjunction with the --yv12 and
--i420 options. If the -o option is not specified, the output will be
directed to stdout.
