Cast to TV GNOME Shell extension v10 brings Playercast app support, allowing users to cast media files to other Linux devices on the same network remotely, from GNOME Shell.
Cast to TV is a GNOME Shell extension to cast videos, music and pictures to Chromecast or other devices over a local network. It supports video transcoding on the fly (for videos that can't directly play on the device), customizable subtitles, it can show a music visualizer while casting music, and much more. For controlling the device, the Gnome Shell extensions adds a new button on the top panel with playback controls.
The latest v10 release of Cast to TV extension doesn't come with any exciting features for Chromecasts, but it brings support for Playercast app.
Playercast is a small, simple application that runs in the background, turning any Linux computer on the same network, be it another Linux desktop, a Raspberry Pi, etc., into a receiver for Cast to TV. Install Playercast on a Linux device, no matter what desktop environment it's using, and you'll be able to cast media files to it using Cast to TV installed on your host computer.
