BLIND-NEXT-FRAME(1)

📦 version 1.1, in alpine 3.24

💅 blind-next-frame — bestie edition ✨

okay so picture this: you're sitting on a video stream and you just want ONE frame. not the whole thing. one. that's literally this tool. welcome 🫶

This is the blind-next-frame page from the blind manual, and I'm gonna walk you through it like we're texting, but I promise ngl every single detail is still here. 💖

🦋 NAME 🦋

blind-next-frame — extracts the next frame from a video ✨

Like, just the next one. The one after that is a whole other conversation. 💅

🌸 SYNOPSIS 🌸

blind-next-frame [-f frames] width height pixel-format ...

🎀 DESCRIPTION 🎀

okay so here's the vibe: blind-next-frame reads the first frame available in stdin, and prints it, with a head, to stdout. that's it. that's the whole job. 👑

and the icon behaviour: no excess bytes are read. none. zero. she's precise like that. so you can run blind-next-frame again to extract the next next frame. it just picks up right where it left off. main character energy fr fr. ✨

You must specify the width, height, and pixel format of the video — with width, height, and pixel-format, respectively. like, she can't guess bestie, she needs the numbers. 😭 And heads up: blind-read-frame(1) is used to extract this information. so that's your source for the deets.

And here's the cute part — any argument following pixel-format is appended to pixel-format with a <space> in between. so anything extra you throw at the end just gets glued onto the pixel format with a space. boom. 🫶

✨ OPTIONS ✨

  • -f frames — Read and output the first frames frames rather than the first single frame. so instead of one little frame you get a whole lil batch. slay. 💖

💀 EXIT STATUS 💀

  • 0 — Successful completion. we ate and left no crumbs. 🎉
  • 1 — End of file reached, no more frames available. that's it, that's the end of the video, nothing left to give. 😭
  • 2 — An error occurred. something went wrong, and honestly? rude. 🙈
