VP8 Postprocessing Options:

--noise-level= <arg>

Enable VP8 postproc add noise

--deblock

--demacroblock-level= <arg>

Enable VP8 demacroblocking, w/ level

--pp-debug-info= <arg>

Enable VP8 visible debug info

--pp-dbg-ref-frame= <arg>

Display only selected reference frame per macro block

--pp-dbg-mb-modes= <arg>

Display only selected macro block modes

--pp-dbg-b-modes= <arg>

Display only selected block modes

--pp-dbg-mvs= <arg>

Draw only selected motion vectors

--mfqe

Enable multiframe quality enhancement

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.
