💖 GAV1_DECODE 💖

okay so bestie, welcome to the gav1_decode manual page — it lives in section 1 of the General Commands Manual, and it's literally the cutest little decoder app you ever met 🦋

✨ NAME ✨

gav1_decode, — an example application of gav1. gav1_decode can be used to decode IVF files. periodt 💅

🌸 SYNOPSIS 🌸

gav1_decode [options] <input file> [-o <output file>]

like, you give it an input file, you give it options, and if you want an output file you go -o. iconic behaviour tbh 🎀

👑 OPTIONS 👑

okay this is the main character section, let's get into it 🫶

  • -h, --help — this help message. it's giving "help me help you" 💖
  • --threads <positive integer> — (Default 1). a positive integer bestie, positive. we don't do negative threads in this house.
  • --frame_parallel. — frame parallel mode. no extra notes, she's just there, being mysterious ✨
  • --limit <integer> — stop decoding after N frames (0 = all). so 0 means go feral, decode everything 🔥
  • --skip <integer> — skip initial N frames (Default 0). sometimes you gotta skip to the good part, no cap.
  • --version. — version. that's it. that's the whole vibe.
  • --y4m — (Default false). y4m output, off by default.
  • --raw — (Default true). raw output, on by default. lowkey the default default.
  • -v — logging verbosity, can be used multiple times. stack those -vs, go wild, more v's = more lore 👑
  • --all_layers. — all layers. every single one. she contains multitudes 💜
  • --operating_point <integer between 0 and 31> — (Default 0). the integer has to be between 0 and 31, that's the range, don't try anything cute 🙈
  • --frame_timing <file> — output per-frame timing to <file> in tsv format.
⚠️ heads up bestie: this yields meaningful results only when frame parallel is off. so if you want real numbers, --frame_parallel has gotta go sit down. 💀

🧚 Advanced settings 🧚

ooh she has an advanced section, main character energy fr fr ⭐

  • --post_filter_mask <integer> — (Default 0x1f).

a mask indicating which post filters should be applied to the reconstructed frame. this may be given as octal, decimal or hexadecimal — pick your fighter, all three are valid 🎀

from LSB (least significant bit, starting at bit 0, going up):

  • Bit 0: Loop filter (deblocking filter)
  • Bit 1: Cdef
  • Bit 2: SuperRes
  • Bit 3: Loop Restoration
  • Bit 4: Film Grain Synthesis

so that default 0x1f is literally all five bits lit up — the full filter slay ✨

libgav1 0.16.1 — max bitdepth: 10, build configuration: Not available.

that's the whole build deets, iykyk 💅
