STRUCT V4L2_VP9_FRAME_MV_CONTEXT(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… struct v4l2_vp9_frame_mv_context β€” NAME

okay so bestie, this is struct v4l2_vp9_frame_mv_context from the Kernel API Manual, and it's basically the motion vector probability storage era πŸŽ€ β€” that's the whole vibe. It holds all the motion vector-related probabilities, one little u8 corner at a time.


✨ SYNOPSIS ✨

no cap, here's the whole struct, copy it exactly:

struct v4l2_vp9_frame_mv_context {
    u8 joint[3];
    u8 sign[2];
    u8 classes[2][10];
    u8 class0_bit[2];
    u8 bits[2][10];
    u8 class0_fr[2][2][3];
    u8 fr[2][3];
    u8 class0_hp[2];
    u8 hp[2];
 };

🫢 Members 🫢

the way each field is literally just a probability bucket, i'm obsessed:

  • joint β€” motion vector joint probabilities. three of them, living their best life 🌸
  • sign β€” motion vector sign probabilities.
  • classes β€” motion vector class probabilities.
  • class0_bit β€” motion vector class0 bit probabilities πŸŽ€
  • bits β€” motion vector bits probabilities.
  • class0_fr β€” motion vector class0 fractional bit probabilities.
  • fr β€” motion vector fractional bit probabilities.
  • class0_hp β€” motion vector class0 high precision fractional bit probabilities ✨
  • hp β€” motion vector high precision fractional bit probabilities.
