💖 yuvinactive(1) — the MJPEG tools manual, but make it make sense 💖

okay bestie, gather round, because yuvinactive is one of those lil MJPEG tools that's lowkey iconic once you get what it's doing 🎀 it lives in the MJPEG tools manual and it's here to help you ✨hide stuff✨ in your video.

🌸 NAME 🌸

yuvinactive — set a part of the video to a defined state

✨ SYNOPSIS ✨

yuvinactive [options] </dev/stdin >/dev/stdout

🦋 DESCRIPTION 🦋

so the whole vibe here is: you draw an imaginary rectangle on your video, and yuvinactive does something to just that rectangle. main character energy, but for a box. 💅

by default it makes that area really black. like, fully black. but you can also tell yuvinactive to darken the area, or fill it with a certain color. it can also make the content of the area unreadable — think extreme softening of the area, like a blur that ate too much sugar 😭. or it can copy the surrounding area into the specified area. slay.

usually you gotta use the -i option, which sets the area in which yuvinactive will work. if no additional option is given, yuvinactive sets the area to black. but you can use the -d, -s, -a, -c options to tell yuvinactive that it shall do something different with that area. and here's the thing — you can only use one additional option. just one. pick your fighter. 🫶

yuvinactive was built to remove unwanted things like a logo, from the movie. yes, it's giving "logo begone". 💀

💅 OPTIONS 💅

lav2yuv accepts the following options:

🙈 okay so the man page literally says lav2yuv here, not yuvinactive. no cap, that's what it says. keeping it real, keeping it exact.

• -h — some help output. she's a little vague, but she's there for you. 🌸
• -iXxY+XOFF+YOFF — specifies the area yuvinactive shall work with. with this option the area is set to black. there are no restrictions because of interlacing. 👑
• -d num — how much darker the area should be compared to the original color. this is done by setting a lower value for the luma. the value is in percent from the original luma. dark academia aesthetic, but for pixels. 🖤
• -s num — here you specify a certain color in the yuv format. 🎨
• -a num — with this option the program uses one pixel and averages the surrounding pixels with the same color to make the original less readable. the number tells the program how many pixels around the original pixel should be overwritten with the same color. you have to use an even number here. (even numbers only bestie, it's not a suggestion 💀)
• -c num — sets the number of surrounding pixels yuvinactive should use to copy them into the given area. you have to use an even number here. yuvinactive uses the lines above and below the specified area for copying them into the area. 🧚

💀 BUGS 💀

right, there are bugs hidden. the thing is not well tested, and not every option might work. yuvinactive is in the first state of becoming a useful program. so like… she's a work in progress, she's growing, we love her anyway. 🌈 (but fr fr, expect some chaos.)
