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:

- WebM Project VP8 Decoder v1.6.0
- WebM Project VP9 Decoder v1.6.0
