dav1d(1)

💖 dav1d — like, the manual page, bestie 💖

okay so this is dav1d(1), from the General Commands Manual, and honestly? she's an icon. let's get into it 🫶

✨ NAME ✨

dav1d — a fast and small AV1 video stream decoder. yes, both. fast and small. she contains multitudes 💅

🌸 SYNOPSIS 🌸

dav1d [options]

that's it. that's the whole vibe. you give her options, she gives you decoded video. iconic behaviour, no notes.

🦋 DESCRIPTION 🦋

dav1d is an AOMedia Video 1 (AV1) decoder, cross-platform, and she is focused — like, laser-focused — on speed and correctness. not one or the other. both. main character energy fr fr.

here's everything she supports, and bestie, it's a lot:

• Support for all features of the AV1 bitstream. all of them. every single one. 👑
• 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

like… she really said "I'll do all of it" and then did all of it. obsessed.

🎀 OPTIONS 🎀

one bullet per option, bestie, exactly like the original, no skipping, no summarising, we respect the source material in this house 💖

• -i, --input=$file — the input file. required, so like… don't forget her, she's not optional, she's the whole point 🙈
• -o, --output=$file — the output file.
• --demuxer=$name — force the demuxer type. your choices are 'ivf' or 'annexb'. default? she detects it from the extension, she's smart like that 💅
• --muxer=$name — force the muxer type. options are 'md5', 'yuv', 'yuv4mpeg2' or 'null'. default: detect from extension, again, she just knows ✨
• -q, --quiet — disable status messages. for when you want her to stop texting you updates 🫶
• -l, --limit=$num — stop decoding after $num frames. she'll know when to stop, she has boundaries 💅
• -s, --skip=$num — skip decoding of the first $num frames. not me ignoring the first bit, lowkey relatable 😭
• -v, --version — print version and exit. quick lil hello, then she's gone.
• --framethreads=$num — number of frame threads (default: 1).
• --tilethreads=$num — number of tile threads (default: 1).
• --filmgrain — enable film grain application (default: 1, except if muxer is md5). the ✨aesthetic✨ grain stays on unless you're doing md5, in which case, nope.
• --oppoint=$num — select an operating point of a scalable AV1 bitstream, range 0 - 32.
• --alllayers=$num — output all spatial layers of a scalable AV1 bitstream (default: 1). all the layers. like an onion but make it video 🧅
• --verify=$md5 — verify decoded md5. implies --muxer md5, no output. so heads up, she's checking, not writing 👀
• --cpumask=$mask — restrict permitted CPU instruction sets. values are 0, 'sse2', 'ssse3', 'sse41', 'avx2' or 'avx512'. default: -1. vibe check your CPU before you go wild 💀
