The avconv utility can be made to work in 'the Unix way' by specifying stdin and/or stdout instead of filenames for the input and output respectively. See: http://libav.org/avconv.html#pipe

Example:

cat input.ts | avconv -i pipe:0 -f mp4 -movflags frag_keyframe pipe:1 | cat > output.mp4

Using node's require('child_process').spawn(), we can pipe streams of video data through avconv's stdin and stdout and thus Stream All The Things.

OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

	package main

	import (
	"code.google.com/p/go.net/websocket"
	//"github.com/garyburd/go-websocket/websocket"
	//"github.com/zhangpeihao/gowebsocket"
	"net/http"
	"net/rpc"
	"net/rpc/jsonrpc"
	)

	var WebSocketServer = require('ws').Server;
	var wss = new WebSocketServer({port: 8080});

	var jwt = require('jsonwebtoken');

	/**
	The way I like to work with 'ws' is to convert everything to an event if possible.
	**/
	function toEvent (message) {
	try {

	#!/bin/bash
