# dav1d(1)

fast and small AV1 video stream decoder

## NAME

dav1d - fast and small AV1 video stream decoder

## SYNOPSIS

**dav1d** \[*options*\]

## DESCRIPTION

dav1d is an AOMedia Video 1 (AV1) cross-platform decoder and focused on speed and correctness. dav1d supports the following features: Support for all features of the AV1 bitstream. Support for all bitdepth, 8, 10 and 12bits. Support for all chroma subsamplings 4:2:0, 4:2:2, 4:4:4 and grayscale. Full acceleration for AVX-2 64bits processors. Partial acceleration for SSSE3 processors. Partial acceleration for NEON processors.

## OPTIONS

- **-i**, **--input**=*$file*

  input file (required)

- **-o**, **--output**=*$file*

  output file

- **--demuxer**=*$name*

  force demuxer type ('ivf' or 'annexb'; default: detect from extension)

- **--muxer**=*$name*

  force muxer type ('md5', 'yuv', 'yuv4mpeg2' or 'null'; default: detect from extension)

- **-q**, **--quiet**

  disable status messages

- **-l**, **--limit**=*$num*

  stop decoding after $num frames

- **-s**, **--skip**=*$num*

  skip decoding of the first $num frames

- **-v**, **--version**

  print version and exit

- **--framethreads**=*$num*

  number of frame threads (default: 1)

- **--tilethreads**=*$num*

  number of tile threads (default: 1)

- **--filmgrain**

  enable film grain application (default: 1, except if muxer is md5)

- **--oppoint**=*$num*

  select an operating point of a scalable AV1 bitstream (0 - 32)

- **--alllayers**=*$num*

  output all spatial layers of a scalable AV1 bitstream (default: 1)

- **--verify**=*$md5*

  verify decoded md5. implies --muxer md5, no output

- **--cpumask**=*$mask*

  restrict permitted CPU instruction sets (0, 'sse2', 'ssse3', 'sse41', 'avx2' or 'avx512'; default: -1)
