Output File Patterns:
-
The
-oargument 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
--yv12and--i420options. If the-ooption is not specified, the output will be directed to stdout.
