STRUCT HVA_ENC(9)

🎀 struct hva_enc(9) 🎀

okay so bestie, welcome to the Kernel API Manual — this is the page for struct hva_enc, aka the hva encoder. it's giving "the blueprint every encoder has to fill out" energy, and honestly? iconic. let's get into it 💅

---

✨ NAME ✨

struct hva_enc — hva encoder

like, literally the struct that is an encoder. no cap 🫶

---

🌸 SYNOPSIS 🌸

struct hva_enc {
    const char      *name;
    u32 streamformat;
    u32 pixelformat;
    u32 max_width;
    u32 max_height;
    int (*open)(struct hva_ctx *ctx);
    int (*close)(struct hva_ctx *ctx);
    int (*encode)(struct hva_ctx *ctx, struct hva_frame *frame, struct hva_stream *stream);
};

look at her. main character struct. every field is a whole personality trait 💖

---

🦋 Members 🦋

okay so let's go member by member, bestie, because each one matters:

• name — the encoder name. it's her name. her whole identity. say it with your chest ✨
• streamformat — fourcc code for compressed video format (H.264...). yes, the compressed one, the squeezed one 🍓
• pixelformat — fourcc code for uncompressed video format. the raw, unbothered, unfiltered version 💅
• max_width — maximum width of frame for this encoder. she has limits, and that's healthy 🌸
• max_height — maximum height of frame for this encoder. same vibe, vertical edition 🎀
• open — open encoder. wake her up, do her hair 💖
• close — close encoder. nap time, she earned it 😭
• encode — encode a frame (struct hva_frame) in a stream (struct hva_stream). this is the moment, this is the whole point, this is when she slays 🔥👑

mwah, go write some encoders, ily 🫶💖
