Defined in:
lib/airvideo.rb

Overview

The AirVideo Client. At this stage it can emulate the iPhone app in all major features.

Minor features, such as requesting a specific streams when using the Live Conversion feature aren’t yet supported, but it’s just a question of figuring out what the server is expecting.

Setting #max_height and #max_width should be working with the Live Conversion, but for some reason it’s not quite happening. Defaults are 640x480

Defined Under Namespace

Constructor Details

#initialize(server, port = 45631, password = nil) ⇒ Client

Specify where your AirVideo Server lives. If your HTTP_PROXY environment variable is set, it will be honoured.

At the moment I’m expecting ENV to have the form ‘sub.domain.com:8080’, I throw an http:// and bung it into URI.parse for convenience.

Instance Method Details

#cd(dir) ⇒ Object

Changes to the given directory. Will accept an AirVideo::FolderObject or a string. Returns the AirVideo::Client instance, so you can string commands:

AirVideo::Client.new('127.0.0.1').ls[0].cd.ls

NB. This will not check to see if the folder actually exists!
