You can watch your friends’ games with the click of a button via Steam Broadcasting, now available in beta. When you see a friend in game, simply click on "Watch Game" from their profile or from the Steam Client Friend's List to open a window into their gameplay -- no game ownership, special fees, or additional apps required.

The beta is open to everyone on Steam who wants to participate by opting in to the Steam Client beta through the Steam Settings panel. For the time being, concurrent viewing may be limited as the beta is scaled up to support the broader audience.
(View => settings => BEta participation => restart steam).

We hope to see you soon broadcasting !

The first wave of participants has been invited to the Steam Music Beta!

We're happy to announce that anyone running SteamOS will automatically have access to the feature once they opt to participate in the Steam Client Beta (via System Settings.) Others may express interest in beta participation by joining the Steam Music group. Members will receive email invites in waves, until the feature is released to everyone.

We've received a number of questions about Steam Music since our announcement of the feature, so here's a round-up of information about Steam Music.

Why is Valve adding music features to its Steam client?
For years, customers have been asking us to provide a basic way for them to access and play music while in-game. Task-switching between resource-intensive 3D games and other desktop apps has never been a graceful experience for gamers, so an in-game player can help by eliminating that pain point.

Beyond addressing this context-switching hurdle, we see an opportunity to broaden Steam as an entertainment platform which includes music alongside games and other forms of media. With our ongoing efforts to make Steam accessible in the living room with SteamOS and Steam Machines, the timing feels right for us to make an investment in this broader picture.

Why build a local music player when streaming services have become the status quo?
Like many new features of Steam, we’ve aimed to introduce a basic, reasonable set of features to begin a beta. With your beta feedback in mind, we hope to build more features, creating the experience that’s most compelling to our customers. Interested in some sort of streaming music experience? Let us know what you're looking for in the discussions.

What file types does the Steam Music player support?
Steam supports MP3s at this point in time, with support for more file types on the way.

How can I join the Steam Music Beta?
The beta is invite-only at this time, and requesting an invite on the forums will do you no good. Instead, to express interest in beta participation, simply join the Steam Music group. A random selection of group members will receive email invites in waves, until the feature is released to everyone.

I’m in the beta! How do I add my music collection to my Steam library?
First, be sure you’re opted into the Steam Client Beta (via Settings) and using SteamOS or Big Picture mode. Then, you can point Steam to your collection of MP3 files on a local hard drive. This is done either through Music Settings or the “+” button in Steam’s “Recently Played” view.

I’m running SteamOS. How do I get my music collection onto my Steam machine?
You can either attach an external drive containing your collection of MP3s, or visit the SteamOS desktop and transfer files from the source of your choice to your hard drive there. Once available as local MP3s, SteamOS will detect these files when you point Steam to their location on disk.

Does Steam Music work with In-Home Streaming?
When connecting to a remote computer to play, you can also stream its music files via the Steam Overlay.

Hey, where is the desktop user interface?
On its way!

Where is that one feature I really care about?
Unless you’re simply a big fan of the “Play” button, you may not find your favorite music feature exists here just yet. This beta is being conducted in large part to gather your feedback and respond with additional feature investments as they make sense. Hoping to route your music through your Steam controller’s haptic pistons like a freaky kazoo? Let us know in the discussions.

Will music be sold on Steam?
Steam currently offers a number of game soundtracks for sale. Your feedback will help guide where we take things next.

What features can we expect to be added to Steam Music?
Head to the forums, and join the conversation. Again, your feedback will inform what becomes of Steam Music.

Steam Machines - Prototype Details
Hello from the Steam hardware bunker.

Thanks for joining the Steam Universe community group. As we get closer to shipping the prototype Steam Machines and controllers we talked about last week, we're going to be posting info here about what we're up to, and give you some insight into the work we’ve done to get to this point.

As we talked about last week, the Steam Machines available for sale next year will be made by a variety of companies. Some of those companies will be capable of meeting the demands of lots of Steam users very quickly, some will be more specialized and lower volume. The hardware specs of each of those machines will differ, in many cases substantially, from our prototype.

Valve didn't set out to create our own prototype hardware just for the sake of going it alone - we wanted to accomplish some specific design goals that in the past others weren't yet tackling. One of them was to combine high-end power with a living-room-friendly form factor. Another was to help us test living-room scenarios on a box that's as open as possible.

So for our own first prototype Steam Machine ( the one we're shipping to 300 Steam users ), we've chosen to build something special. The prototype machine is a high-end, high-performance box, built out of off-the-shelf PC parts. It is also fully upgradable, allowing any user to swap out the GPU, hard drive, CPU, even the motherboard if you really want to. Apart from the custom enclosure, anyone can go and build exactly the same machine by shopping for components and assembling it themselves. And we expect that at least a few people will do just that. (We'll also share the source CAD files for our enclosure, in case people want to replicate it as well.)

And to be clear, this design is not meant to serve the needs of all of the tens of millions of Steam users. It may, however, be the kind of machine that a significant percentage of Steam users would actually want to purchase - those who want plenty of performance in a high-end living room package. Many others would opt for machines that have been more carefully designed to cost less, or to be tiny, or super quiet, and there will be Steam Machines that fit those descriptions.

Here are the specifications for Valve's 300 prototypes.

The 300 prototype units will ship with the following components:
GPU: some units with NVidia Titan, some GTX780, some GTX760, and some GTX660
CPU: some boxes with Intel i7-4770, some i5-4570, and some i3
RAM: 16GB DDR3-1600 (CPU), 3GB GDDR5 (GPU)
Storage: 1TB/8GB Hybrid SSHD
Power Supply: Internal 450w 80Plus Gold
Dimensions: approx. 12 x 12.4 x 2.9 in high

As a hardware platform, the Steam ecosystem will change over time, so any upgrades will be at each user's discretion. In the future we'll talk about how Steam will help customers understand the differences between machines, hardware strengths and weaknesses, and upgrade decisions.

We aren't quite ready to post a picture of our prototype - just because they're not finished enough. Before they ship we'll let you know what the prototype looks like. And we expect people to redesign the machine, too. Both from a technical perspective, deciding on different components, and from an industrial design perspective, changing the enclosure in interesting ways.

So high-powered SteamOS living room machines are nice, and fun to play with, and will make many Steam customers happy. But there are a lot of other Steam customers who already have perfectly great gaming hardware at home in the form of a powerful PC. The prototype we're talking about here is not meant to replace that. Many of those users would like to have a way to bridge the gap into the living room without giving up their existing hardware and without spending lots of money. We think that's a great goal, and we're working on ways to use our in-home streaming technology to accomplish it - we'll talk more about that in the future.

Stay tuned for some closer looks at the Steam Controller.
