       --md5  Compute the MD5 sum of the decoded frame

       --error-concealment
              Enable decoder error-concealment

       -k, --keep-going
              (debug) Continue decoding after error

   VP8 Postprocessing Options:
       --noise-level=<arg>
              Enable VP8 postproc add noise

       --deblock
              Enable VP8 deblocking

       --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.

   Included decoders:
       vp8    - WebM Project VP8 Decoder v1.6.0

       vp9    - WebM Project VP9 Decoder v1.6.0
