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.

Included decoders:

- av1
