ENUM V4L2_AV1_FRAME_RESTORATION_TYPE(9)

💅 enum v4l2_av1_frame_restoration_type(9) — AV1 Frame Restoration Type

okay bestie, welcome to the Kernel API Manual ✨ this one's a lil enum that tells you which restoration filter is getting applied to an AV1 frame. Short page, iconic energy, let's go 🎀

✨ NAME ✨

enum v4l2_av1_frame_restoration_type — AV1 Frame Restoration Type 🦋

🌸 SYNOPSIS 🌸

enum v4l2_av1_frame_restoration_type {
    V4L2_AV1_FRAME_RESTORE_NONE ,
    V4L2_AV1_FRAME_RESTORE_WIENER ,
    V4L2_AV1_FRAME_RESTORE_SGRPROJ ,
    V4L2_AV1_FRAME_RESTORE_SWITCHABLE

};

⭐ Constants ⭐

the whole vibe check, one constant at a time 👑

• V4L2_AV1_FRAME_RESTORE_NONE — literally nothing happens here, no filtering is applied. the "I'm just here for the vibes" option 💀
• V4L2_AV1_FRAME_RESTORE_WIENER — the Wiener filter process is invoked 🔥 she's doing the work.
• V4L2_AV1_FRAME_RESTORE_SGRPROJ — the self guided filter process is invoked 🌈 different filter, same main character energy.
• V4L2_AV1_FRAME_RESTORE_SWITCHABLE — the restoration filter is swichtable (yes that's the spelling that's in the source, we are Not touching it, iykyk 💅).
