STRUCT V4L2_HDMI_COLORIMETRY(9)

🌈 NAME ✨

okay so welcome to the Kernel API Manual bestie, and today's main character is struct v4l2_hdmi_colorimetry — literally the struct that describes the HDMI colorimetry information 💅

🎀 SYNOPSIS 🎀

no cap, here's the whole shape of it, character for character:

struct v4l2_hdmi_colorimetry {
    enum v4l2_colorspace colorspace;
    enum v4l2_ycbcr_encoding ycbcr_enc;
    enum v4l2_quantization quantization;
    enum v4l2_xfer_func xfer_func;
 };

💖 Members 💖

four members, four little icons, all serving their own vibe:

• colorspace — it's an enum v4l2_colorspace, and it's the colorspace 🌈
• ycbcr_enc — it's an enum v4l2_ycbcr_encoding, aka the Y'CbCr encoding 🦋
• quantization — it's an enum v4l2_quantization, and it holds the colorspace quantization ⭐
• xfer_func — it's an enum v4l2_xfer_func, holding the colorspace transfer function ✨
