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.

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


	async Task CompileModelAsync()
	{
	//Define remote URL
	var model_remote_url = "";
	var model_name = "FruitModel";
	var model_file_extension = "mlodel";

	string path = Environment.GetFolderPath(Environment.SpecialFolder.Personal);
	string model_path = Path.Combine(path, $"{model_name + model_file_extension}");

	public class GzipWebClient : WebClient
	{
	protected override WebRequest GetWebRequest(Uri address)
	{
	var request = base.GetWebRequest(address);
	if(request is HttpWebRequest)
	{
	((HttpWebRequest)request).AutomaticDecompression = DecompressionMethods.Deflate \| DecompressionMethods.GZip;
	}

	Logger.Info("Sending analytics request to Segment.io ..", props);

	var start = DateTime.Now;

	HttpResponseMessage response = null;

	try {
	//breakpoint hit
	response = _client.SendAsync(request).Result;

	public class EventArgs<T> : EventArgs
	{
	public T Data { get; set; }

	public EventArgs (T data)
	{
	Data = data;
	}

	public static EventArgs<T> From (T data)

	if (UIDevice.CurrentDevice.CheckSystemVersion (6, 0))
	{
	var status = ABAddressBook.GetAuthorizationStatus();
	if (status == ABAuthorizationStatus.Denied \|\| status == ABAuthorizationStatus.Restricted) {
	// no address book
	} else {
	if (this.addressBook == null)
	this.addressBook = new ABAddressBook();

	if (status == ABAuthorizationStatus.NotDetermined) {

	public static ABAddressBook Create (out NSError error)
	{
	IntPtr intPtr;
	IntPtr value = ABAddressBook.ABAddressBookCreateWithOptions (IntPtr.Zero, out intPtr);
	ABAddressBook result;
	if (value == IntPtr.Zero)
	{
	error = new NSError (intPtr);
	result = null;
	}

	public class MyViewController : UIViewController {

	public override void ViewDidLoad ()
	{
	base.ViewDidLoad ();
	for (int i = 0; i < Int32.MaxValue; i++) {
	DoStuffAsync();
	}
	}
