Stéphan KochenKinda stuck on <a href="https://hachyderm.io/tags/FFmpeg" class="mention hashtag" rel="nofollow noopener" target="_blank">#FFmpeg</a>.I'm using libavcodec to decode a HEVC stream, but when I render it with <a href="https://hachyderm.io/tags/SDL3" class="mention hashtag" rel="nofollow noopener" target="_blank">#SDL3</a>, the image is squished vertically, with bars above and below.Strangely, I also have a hardware accelerated path working on RPi 5 (from their FFmpeg branch) using DMABufs and `eglCreateImage` and that is instead squished _horizontally_.There's no crop or weird pixel aspect according to the AVFrame. Feels like I'm missing something simple. 😕

aaronI just had the idea that it’d be cool to create a FUSE filesystem that transcodes modern audio formats to MP3 on the fly, so I can play my music collection (mostly AAC and ALAC) in Winamp on one of my Windows 98 machines.

PeterOh, FFS! Are people really only now realising that writing assembly code leads to faster processing?> wielding the art of handwritten assembly codeI cut my teeth on machine language and assembly code. Interpreted and compiled languages never gave faster *results*, they just allowed faster *coding*, which meant saving money on wages.Come to think of it, that was in the 1970s, so modern coders probably equate it to alchemy and the dark arts.<a href="https://www.tomshardware.com/software/the-biggest-speedup-ive-seen-so-far-ffmpeg-devs-boast-of-another-100x-leap-thanks-to-handwritten-assembly-code" rel="nofollow noopener" translate="no" target="_blank">https://www.tomshardware.com/software/the-biggest-speedup-ive-seen-so-far-ffmpeg-devs-boast-of-another-100x-leap-thanks-to-handwritten-assembly-code</a><a href="https://theblower.au/tags/Coding" class="mention hashtag" rel="nofollow noopener" target="_blank">#Coding</a> <a href="https://theblower.au/tags/Computers" class="mention hashtag" rel="nofollow noopener" target="_blank">#Computers</a> <a href="https://theblower.au/tags/FFMPeg" class="mention hashtag" rel="nofollow noopener" target="_blank">#FFMPeg</a> <a href="https://theblower.au/tags/CodersAssemble" class="mention hashtag" rel="nofollow noopener" target="_blank">#CodersAssemble</a>

Rich Puchalsky ⩜⃝Let's take <a href="https://mastodon.social/tags/ffmpeg" class="mention hashtag" rel="nofollow noopener" target="_blank">#ffmpeg</a> as an example -- a project under a GNU license. You're going to do something with video not through a shittified package? You pretty much need ffmpeg.Not sure how it is on other platforms, but ffmpeg on a mac does not follow a single one of the general rules that user expects for installing something on a mac. Does it show up as a program in Applications? No. It's a command line install. How do you know if it's installed? Command line.

Paco Hope #resistOk, any <a href="https://infosec.exchange/tags/video" class="mention hashtag" rel="nofollow noopener" target="_blank">#video</a> folks out there who know how to do what I want to do? I don't know what words to search for because I don't know what this technique is called. Boosts welcome, suggestions welcome.I have a pool cleaning robot. Like a roomba, but for the bottom of the pool. We call it poomba. Anyways, I want to shoot an MP4 video with a stationary camera (a GoPro) looking down on the pool while the robot does its work. So I will have this overhead video of like 3-4 hours.I want to kinda overlay all the frames of the video into a single picture. So the areas where the robot drove will be dark streaks (the robot is black and purple). And any area the robot didn't cover would show the white pool bottom. Areas the robot went over a lot would be darker. Areas it went rarely would be lighter.I'm just super curious how much coverage I actually get. This thing isn't a roomba. It has no map and it definitely doesn't have an internet connection at the bottom of the pool. (Finally! A place they can't get AI, yet!) It's just using lidar, motion sensors, attitude sensors and some kind of randomizing algorithm.I think of it like taking every frame of the video and compositing it down with like 0.001 transparency. By the end of the video the things that never changed (the pool itself) would be full brightness and clear. While the robot's paths would be faint, except where it repeated a lot, which would be darker.I could probably rip it into individual frames using <a href="https://infosec.exchange/tags/ffmpeg" class="mention hashtag" rel="nofollow noopener" target="_blank">#ffmpeg</a> and then do this compositing with <a href="https://infosec.exchange/tags/ImageMagick" class="mention hashtag" rel="nofollow noopener" target="_blank">#ImageMagick</a> or something (I'm doing this on <a href="https://infosec.exchange/tags/Linux" class="mention hashtag" rel="nofollow noopener" target="_blank">#Linux</a>). But 24fps x 3600 seconds/hour x 3 hours == about 260K frames. My laptop will take ages to brute force this. Any more clever ways to do it?If I knew what this technique/process was called, I'd search for it.

Tommi 🤯 @ WHY 📞9848So I have hundreds of videos of ~1 minute recorded from my phone ~10 years ago, and they generally don’t have that great compression, nor they are stored in a modern and advanced video format.For archiving purposes, I want to take advantage of my workstation’s mighty GPU to process them so that the quality is approximately the same, but the file size would be strongly reduced.Nevertheless, compressing videos is terribly hard, and way more complex than compressing pictures, so I wouldn’t really know how to do this, what format to use, what codec, what bitrate, what parameters to keep an eye on, etc.I don’t care if the compression takes a lot of time, I just want smaller but good looking videos.Any tips? (Links to guides and tutorials are ok too)Also, unfortunately I am forced to use Windows for this (don’t ask me why 🫠), but I know nothing about Windows because I hate it.

doboprobodyne<a href="https://mathstodon.xyz/@christianp" class="u-url mention" rel="nofollow noopener" target="_blank">@christianp</a> Just a thought, from a knuckle-dragging biology scientist.
