# vpxdec(1)

VP8 and VP9 video decoding encoding tool

## NAME

vpxdec - VP8 and VP9 video decoding encoding tool

## SYNOPSIS

**vpxdec** *\<options\> -o dst\_filename src\_filename*

## OPTIONS

- **--codec=**\<arg\>

  Codec to use

- **--yv12**

  Output raw YV12 frames

- **--i420**

  Output raw I420 frames

- **--flipuv**

  Flip the chroma planes in the output

- **--rawvideo**

  Output raw YUV frames

- **--noblit**

  Don't process the decoded frames

- **--progress**

  Show progress after each frame decodes

- **--limit=**\<arg\>

  Stop decoding after n frames

- **--skip=**\<arg\>

  Skip the first n input frames

- **--postproc**

  Postprocess decoded frames

- **--summary**

  Show timing summary

- **-o** \<arg\>, **--output=**\<arg\>

  Output file name pattern (see below)

- **-t** \<arg\>, **--threads=**\<arg\>

  Max threads to use

- **--frame-parallel**

  Frame parallel decode

- **-v**, **--verbose**

  Show version string

- **-S**, **--scale**

  Scale output frames uniformly

- **--frame-buffers=**\<arg\>

  Number of frame buffers to use

- **--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
