chromecast

Chromecast

Implements a basic number of the google chromecast commands. Other than the basic commands, it also allows you to play media files from your computer either individually or in a playlist; the playlist command will look at all the files in a folder and play them sorted by numerically.

Media Content Playable

Can play / load a local media file on your chromecast.

Supported Media formats:
    - MP3
    - AVI
    - MKV
    - MP4
    - WebM

If an unknown file is found, it will use ffmpeg to transcode it to MP4, and stream it to the chromecast.

Cast DNS Lookup

A DNS multicast is used to determine the Chromecast and Google Home devices.

The cast DNS entry is also cached, this means that if you pass through the device name, -n <name>, or the device uuid, -u <uuid>, the results will be cached and it will connect to the chromecast device instanly.

Playlist

There is support for playing media items as a playlist.

If playing from a playlist, you are able to pass though the --select flag, and this will allow you to select the media to start playing from. This is useful if you have already played some of the media and want to start from one you haven't played yet.

A cache is kept of played media, so if you are playing media from a playlist, it will check to see what media files you have recently played and play the next one from the playlist. --continue=false can be passed through and this will start the playlist from the start.

Watching a Device

If you would like to see what a device is sending, you are able to watch the protobuf messages being sent from your device:

$ go-chromecast watch
