Couchcast
by The Couchcast Authors
Watch an HDMI capture device and control it with a gamepad
About
Couchcast turns a Fire TV, Android TV box, or other streaming stick captured over HDMI into what feels like a native app on your Linux PC or Steam Deck. It shows the live low-latency video and audio full-screen and forwards your controller and keyboard input back to the device, so you can navigate and play from the couch with just a gamepad. Features: - Low-latency full-screen video from any V4L2 HDMI capture device - Audio passthrough kept in sync with the video - Controller input forwarded to the device (Fire TV / Android TV over ADB) - Editable button mapping - Fully controller-navigable — no mouse required, built for SteamOS Gaming Mode
