💅 tvp514x_querystd(9) 💅

okay bestie, this is the Kernel API Manual entry for tvp514x_querystd(9) — a very specific little V4L2 decoder handler, and yes it’s giving niche-but-iconic. 💅

🌸 NAME 🌸

tvp514x_querystd — V4L2 decoder interface handler for querystd ✨

✨ SYNOPSIS ✨

int tvp514x_querystd (struct v4l2_subdev *sd , v4l2_std_id *std_id );

🫶 ARGUMENTS 🫶

• sd — pointer to the standard V4L2 sub-device structure, aka the device context this whole vibe check runs through.
• std_id — the standard V4L2 std_id ioctl enum, aka where the detected-standard info goes.

💖 DESCRIPTION 💖

okay so this function returns the current standard detected by TVP5146/47. That’s the whole main-character job. 📺✨

If no active input is detected, then *std_id is set to 0 and the function returns 0. No active input, no drama — just zeroes, bestie. 🫶
