Was streaming from one pc to another using xbox controllers on the client pc. One day it simply stopped working. However unlike original poster, I'm not subscribed to steam beta on host or client. Affected games include Overcooked and Rocket League. Controllers work fine on host and work fine when running other games on the client.
From the official support article on in-home streaming: My game controller input doesn't affect the game. If your game controller isn't recognized by any game, check to see if Steam Big Picture recognizes it in the controller settings on the client computer. You may need to configure your controller there in order to use it for streaming.
The story doesn’t explicitly say it won’t work with oculus, only that AMD can’t make that marketing claim, due to Oculus’ marketing rules. If it doesn’t work week 1, I bet a hack has it.
It used to work great until then, I tried different client OS'es, different remote streaming settings, ethernet, wlan, putting steam in Big Picture. Tried updating drivers on the host, tried both propriatery and opensource drivers on the client.
Ok, I got it working on GNOME on X11. Looks like it doesn't work on Wayland for now. I'd really rather have it working on Wayland desktops, X11 desktops are VERY Insecure. Also to clarify, I was streaming from another computer, this is about video decoding. So please don't start arguments with me about X11 window capture vs Wayland window capture.
You can tune streaming resolution and bitrate for the best experience on your setup with Advanced Settings. Over a 5 GHz network, our target is a resolution of 1080p at 60 frames per second, with good quality for most scenes. If you have a powerful gaming rig, a wired network, and a capable client device, it's possible to stream 4K at 60 FPS.
Today at the Vive Ecosystem Conference 2018 in China, HTC announced that the Vive Focus standalone headset will be able to wirelessly stream PC VR content from both Steam and Viveport over a 5GHz.
While the Wireless Adapter still doesn’t work on Steam Link, Bluetooth is far more open than that dongle. And you can likely expect that Valve will get support for the Xbox One S controller.
