okay so bestie, this is the doc::libswscale(3) manual page — manual name doc::libswscale, we're in the doc namespace, iconic — and it's all about libswscale, the video scaling and pixel format conversion library. Buckle up 🎀

🌸 NAME 🌸

libswscale — video scaling and pixel format conversion library. That's the whole vibe, no cap. 💅

✨ DESCRIPTION ✨

okay so the libswscale library performs highly optimized image scaling and colorspace and pixel format conversion operations. Like, not just doing it — doing it highly optimized. Slay. 🔥

Specifically, this library performs the following conversions:

  • Rescaling: is the process of changing the video size. Several rescaling options and algorithms are available. This is usually a lossy process.
  • Pixel format conversion: is the process of converting the image format and colorspace of the image, for example from planar YUV420P to RGB24 packed. It also handles packing conversion, that is converts from packed layout (all pixels belonging to distinct planes interleaved in the same buffer), to planar layout (all samples belonging to the same plane stored in a dedicated buffer or "plane").
    • This is usually a lossy process in case the source and destination colorspaces differ.
lowkey important: both of those are usually lossy, so don't expect magic teleportation of every pixel. 😭

and that's a wrap on doc::libswscale(3) 💖 the footer is literally just doc::libswscale(3) again — no version or date drama listed, just main character energy repeating their own name, periodt. now go scale something and convert some pixels, bestie. 🦋🌸
