AOMDEC(1)

✨ NAME ✨

okay bestie, so this page is all about aomdec 🦋, the AOMedia Project AV1 Decoder 💜. It lives in the User Commands section, so it's the stuff you type straight into your terminal 💻.

💜 SYNOPSIS 💜

aomdec <options> filename

🎀 OPTIONS 🎀

okay here's the full menu of options, every single one, no cap 💅

• --help — pulls up the usage options and then bounces 👋
• --codec=<arg> — picks which codec to use 🎬
• --yv12 — spits out raw YV12 frames 🍓
• --i420 — spits out raw I420 frames 🌸
• --flipuv — flips the chroma planes in the output 🔄
• --rawvideo — outputs raw YUV frames 🦋
• --noblit — skips processing the decoded frames 🙈
• --progress — shows progress after each frame decodes 📈
• --limit=<arg> — stops decoding after n frames 🛑
• --skip=<arg> — skips the first n input frames ⏭️
• --summary — shows a timing summary ⏱️
• -o <arg>, --output=<arg> — output file name pattern (see below) 📁
• -t <arg>, --threads=<arg> — max threads to use 🧵
• --row-mt=<arg> — turns on row based multi-threading, default: 0 🌀
• -v, --verbose — shows the version string 🔖
• -S, --scale — scales output frames uniformly 📐
• --frame-buffers=<arg> — how many frame buffers to use 🧺
• --md5 — computes the MD5 sum of the decoded frame 🔐
• --framestats=<arg> — outputs per-frame stats in .csv format 📊
• -k, --keep-going — (debug) keeps decoding even after an error 🐛
• --output-bit-depth=<arg> — output bit-depth for decoded frames 🎨
• --annexb — the bitstream is in Annex-B format 📦
• --oppoint=<arg> — picks an operating point of a scalable bitstream 🎚️
• --all-layers — outputs all decoded frames of a scalable bitstream 🌈
• --skip-film-grain — skips applying film grain 🎞️

🗂️ Output File Patterns 🗂️

okay so the -o argument is the name of the file (or files) you're writing to. If it doesn't have any escape characters in it, everything goes into one single file. If it does, the filename gets built by expanding these escape characters:

• %w — frame width
• %h — frame height
• %<n> — frame number, zero padded to <n> places (1..9)

Pattern arguments only work together with --yv12 and --i420. If you don't specify -o, the output gets sent to stdout 📺.
