@Max_Lindblad @FFmpeg github.com/wader/catgolf more here 🥳

@mwader @FFmpeg you got to be shitting me

Post your best FFmpeg memes!

@ponceto91 Thanks for the shoutout! 🥳

Vous connaissez l'utilitaire jq pour manipuler des documents JSON ? Et bien voici fq, un utilitaire proposant des fonctionnalités analogues mais pour des fichiers binaires de formats très différents (mp3, gif, etc ...). A avoir dans sa toolbox ⬇️ github.com/wader/fq

@manic_pixie_agi @morphillogical Strange, have an example? jq should not require new line between values, any whitespace or even no separator is needed in some cases

@DomWitczak @__femb0t there is a game of life video filter so yes i guess :)

@__femb0t But is it Turing complete?

"easy syntax to remember"

@MuskratElno @FFmpeg @type They might be doing new and nobel things but i would guess open source is what makes that even possible

If you say so...

@FFmpeg @type $ yt-dlp -qf hls-636 rumble.com/v5mw93e-jhank-… --output - | ffmpeg -v quiet -i pipe:0 -c copy -f h264 - | fq -Vrd avc_annexb 'grep_by(.nal_unit_type=="sei").sei.data' x264 - core 164 - H.264/MPEG-4 AVC codec - Copyleft 2003-2023 - videolan.org/x264.html - options: cabac=1 ref=5...

@FFmpeg $ yt-dlp -qf hls-636 rumble.com/v5mw93e-jhank-… --output - | mediainfo --Output=JSON - | jq -r '.media.track[] | select(."@type"=="Menu").ServiceProvider' FFmpeg 🤔

@TheYasinSpace Hey, you can probably do all of it in jq if you want: jq -Rs 'split(".")[1] | @base64d | fromjson'

@yashsoni9919 like this jqplay.org/s/lMCcXBsKp9Zb… ?

@orhundev @FFmpeg yes #life" target="_blank" rel="nofollow noopener">ffmpeg.org/ffmpeg-filters…

is @FFmpeg turing complete?

damn, since when ffmpeg can create spectrograms? 🤯 ffmpeg -i file.wav -lavfi showspectrumpic=s=1920x1080:mode=separate spectrogram.png

@awesomekling regnradar.se and onthegomap.com

What's a website you visit regularly that most people don't know about?

@DeclanK 🥳 thanks for the shoutout

fq seems like an interesting tool - inspired by jq for exploring files and binary formats github.com/wader/fq

@HSVSphere @sasuke___420 Mostly shell but it’s used as a query/transform language is a bunch of services

@sasuke___420 Not exactly. Where else is jq used outside of POSIX shells?

jq is a crude solution to a problem that shouldn't even exist. Nushell fixed that

@angealbertini brb pressing fork button

The Winamp source code is released with an awful licence. github.com/WinampDesktop/…

@Jeffinatorator @lemire The decnum one? Could try build jq without decnum support and i think it will use something from libc but not sure. Maybe also try gojq or jaq, might be faster.

Redis is a popular in-memory data structure store that can be used as a database, cache, and message broker. A few hours ago, Redis has adopted the fast_float C++ library for faster number parsing. It lead to performance gains of up to 25% in some instances. Number parsing comes up ridiculously often as a bottleneck. The fast_float C++ library is used by WebKit/Safari, GCC (glibc++), Chromium (Chrome and other browses). Other systems have adopted the same algorithm with an independent implementation: LLVM, Rust, C# (.NET), Go and many other systems.

@joostvanmeeuwen tip: -r if you want to output as a "raw" string

Want to extract just the data you need? Use `jq '.field'` to focus on specific JSON keys. No more noise! 🧘 #jq #JSON #api

@sasuke___420 @haskuya jaq has some jq benchmark stuff, might be interesting also #performance" target="_blank" rel="nofollow noopener">github.com/01mf02/jaq?tab…

@mwader @haskuya this is very silly but I'm happy to steal the included benchmarks

@sasuke___420 @haskuya someone should! there is github.com/jdroob/cjq but it's not very practical (yet)

@haskuya great, you can compile the jq language and i'll make the internal representation for the json documents

@JammUtkarsh ☺️ is nice if you spend a lot of time debugging and transforming binary and text formats!

@mwader Wow, fq looks interesting, I'll check it out.

Bro knowing jq is like a superpower. I processed about 22.86 Million lines of JSON within a few hours. YOU SHOULD LEARN jq. LEARN jq. LEARN jq. LEARN jq. (yes, I'm shouting !!!!!!!!!!!!!!!!!!!!!!!!!!!!)
