Clojure Destructuring Tutorial and Cheat Sheet

Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.

Live stream Xiaomi Ants Smart Camera via FFMPEG

This assumes you have a Xiaomi Ants Smart Camera that still has the open RTSP enabled. I think newer firmware might remove this capability. If you Google enough you can find instructions on how to downgrade.

FFMPEG

FFMPEG is where most of the magic happens. I use OSX and as such am a fan of using Homebrew to install free software. Here is my ffmpeg install command:

brew install ffmpeg --with-faac --with-fdk-aac --with-ffplay --with-fontconfig --with-freetype --with-frei0r --with-libass --with-libbluray --with-libcaca --with-libquvi --with-libsoxr --with-libssh --with-libvidstab --with-libvorbis --with-libvpx --with-opencore-amr --with-openjpeg --with-openssl --with-opus --with-rtmpdump --with-schroedinger --with-speex --with-theora --with-tools --with-webp --with-x265
