ENUM V4L2_MPEG_VIDEO_AV1_PROFILE(9)

🦋 enum v4l2_mp..._av1_profile(9) — AV1 profiles

okay bestie, welcome to the Kernel API Manual entry for this absolute icon of an enum. We're talking AV1 profiles and which ones a decoder can handle — no cap, it's giving "how much AV1 can u actually decode?" energy. The header calls it enum v4l2_mp..._av1_profile(9) so if u saw the truncated name, yep, that's her. 💅

🎀 NAME 🎀

enum v4l2_mpeg_video_av1_profile - AV1 profiles

✨ SYNOPSIS ✨

enum v4l2_mpeg_video_av1_profile {
    V4L2_MPEG_VIDEO_AV1_PROFILE_MAIN ,
    V4L2_MPEG_VIDEO_AV1_PROFILE_HIGH ,
    V4L2_MPEG_VIDEO_AV1_PROFILE_PROFESSIONAL

};

🌸 Constants 🌸

• V4L2_MPEG_VIDEO_AV1_PROFILE_MAIN — compliant decoders must be able to decode streams with seq_profile equal to 0. Simple, main-character, zero drama. 💖
• V4L2_MPEG_VIDEO_AV1_PROFILE_HIGH — compliant decoders must be able to decode streams with seq_profile equal less than or equal to 1. (Yes bestie, that's exactly how the manual says it — "equal less than or equal to"; we're keeping the lore intact. 😭)
• V4L2_MPEG_VIDEO_AV1_PROFILE_PROFESSIONAL — compliant decoders must be able to decode streams with seq_profile less than or equal to 2. Professional behavior only, periodt. 👑

💜 Description 💜

This enum conveys the highest profile a decoder can work with. That's the whole vibe: it's the decoder's ceiling, the "this is how far I can go" energy. ✨
