airstream

Airstream

A command line tool for sending videos and images to airplay-compatible devices (like AppleTV). The airplay protocol can basically play videos in mpeg-4 (mp4, mov, ts, m4v) format that are accessible via http. Thus for sending a local file a webserver will be created, see below.

Local or remote images can be sent directly to an airplay-device.

Playing audio or offering a stream to an airplay device is not yet implemented but is planned to. Do not hesitate to send me any ideas or bug informations.

Installation

gem install airstream

See Troubleshooting below, if you experience any problems while installing.

Basic Usage

Use the output argument to specify the ip-address of the remote device. Remote files will be played directly, local files are hosted with a small webserver (webrick). Check your firewall settings, port 7000 is used to host the file.

airstream http://example.com/sample.mp4 -o 192.168.1.8
airstream /home/me/sample.mp4 -o 192.168.1.8

You can also use wildcards and handle files as usually...

airstream /home/me/*.mp4 -o 192.168.1.8
airstream /home/me/my-birthday-20{08,10,12}.mov -o 192.168.1.8

Use airimg to send images to the airplay device.

airimg http://example.com/photo.png -o 192.168.1.8
airimg ~/Pictures/photo.png

Use -n option to set the interval between switching to the next picture.

airimg ~/Pictures/*.png -n 8

See the help for further command line options. To specify default options use the configuration file initial generated in ~/.airstreamrc.

Controls

airstream only while playing a video file:

q ... quit
> ... skip to next file
'
