I have tried a lot of solutions for IP-camera streams.

Old solutions

1. Vitamio.https://github.com/yixia/Vitamio-iOS
   Result: random crashes and not working cameras

2. https://github.com/kolyvan/kxmovie
   Result: compile time error. I haven't successfully integrated it to my project.

3. GStreamer. https://github.com/sdroege/gst-player

Git/Github step-by-step Workflow

Step-by-step guide for creating a feature or bugfix branch, submit it for code review as a pull request and once approved, merge upstream. This guide is intended for internal developers with push access to all relevant repos.

You should understand rebasing and squashing. For a very good explanation on rebasing and squashing with pull requests see How to Rebase a Pull Request. Also worth reading is the Hacker's Guide to Git.

Angular2 + JSPM cheat sheet

First time setup

• install jspm beta: npm install -g jspm@beta
• set up your project: jspm init
• install dependencies: jspm install angular2 reflect-metadata zone.js es6-shim

This will create a jspm_packages folder, and a config.js file.

Open the config.js file - this file manages options for the System.js loader - tweak it as appropriate

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.
