💅 tuner_fixup_std(9) 🎀

okay so bestie, welcome to the Kernel API Manual ✨ — yes this is a real kernel manpage, yes it's giving "deep magic", and yes you're gonna get it. buckle up 🦋

🌸 NAME 🌸

tuner_fixup_std — force a given video standard variant, no cap 💅

---

✨ SYNOPSIS ✨

v4l2_std_id tuner_fixup_std (struct tuner *t , v4l2_std_id std );

literally the whole signature, character for character, because we don't play about code 🔥

---

🎀 ARGUMENTS 🎀

• t — the tuner internal struct 💖 that's your context bestie, it's the inside-scoop data structure for the tuner
• std — TV standard, the actual standard you're working with ⭐

🧚 DESCRIPTION 🧚

okay so here's the vibe: a few devices or drivers have problem to detect some standard variations 😭 like they just can't tell the variants apart, it's giving "can't read the room".

on other operational systems, the drivers generally have a per-country code, plus some logic to apply per-country hacks 🙈 but listen — the V4L2 API doesn't provide such hacks. periodt. instead, it relies on a proper video standard selection from the userspace application 💅 that's the main character energy right there.

however — and this is the plot twist — as some apps are buggy, not allowing to distinguish all video standard variations, a modprobe parameter can be used to force a video standard match 🌈 so yeah, that's the workaround, that's the whole point of this function 🫶

fr fr: this exists because apps are buggy and we needed a way to force the match. not me being dramatic, that's literally what it says 💀
