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)
