海外TECH	DEV Community	Adding Chat to Your Amazon IVS Live Stream	https://dev.to/aws/adding-chat-to-your-amazon-ivs-live-stream-43i6	Adding Chat to Your Amazon IVS Live StreamWelcome back to this series where we re learning all about live streaming in the cloud with Amazon Interactive Video Service Amazon IVS If you re new to this series here s what we ve covered so far Getting Started Live Streaming in the Cloud with Amazon IVSCreating Your First Live Stream Playback Experience with Amazon IVSEnhancing Your Amazon IVS Playback ExperienceCreating Interactive Live Streaming Experiences Using Timed Metadata with Amazon IVSIn this post we re going to level up the interactivity and add live chat alongside our live stream viewer If you want to play along at home with this blog post you will need to create your own chat room Amazon IVS Chat rooms require custom user tokens so you ll need to plug in your own token and chat endpoint in the embedded demo below to try it out Creating a Chat RoomThe first step here is to create a chat room for our application Free The AWS Free Tier for Amazon IVS provides messages sent and messages delivered every month Sign up to get started for free I should also mention that as of the the published date of this post Amazon IVS Chat is available in the following regions us east us west eu west Keep an eye out for future region support if you are trying to create a chat room in a region other than those listed above Using the ConsoleOne way to create our chat room is by using the Amazon IVS Management Console From the console home page expand Chat and select Rooms From the chat room list page click on Create room On the create room page enter a Room name and leave Default configuration selected under Room configuration The default configuration gives us a maximum message length of characters and messages per second If this is not sufficient for your application you can select Custom configuration and override it as necessary Next under Message review handler leave Disabled selected The message review handler is a really powerful way to provide AI moderation of chat messages via an AWS Lambda function Per the help text When a message review handler is associated with a room it is invoked for each SendMessage request to that room The handler enforces any business logic that has been defined and determines whether to allow deny or modify a message We ll cover using a custom event handler in a future post but for now we ll leave it disabled Enter any desired tags for this resource and then click Create room Our room will be created with no delay and we ll be redirected to the room details page On that page you ll see a summary of the room configuration The important bit that we ll need from this section is the Messaging endpoint Since Amazon IVS Chat rooms are based on WebSockets this is the secure endpoint that we ll use in the frontend to connect to our chat room There is also a panel titled Chat tokens that gives us a helpful tool to generate a chat token for development purposes As I mentioned above if you d like to try the embedded chat experience below you ll need a token and this is one way to generate it Using the AWS CLIWe can also use the AWS CLI to create a chat room via the following command aws ivschat create room name my first ivs chat roomWhich returns the chat room information in JSON format arn arn aws ivschat us east redacted room redacted createTime T id jmJloyMmOy maximumMessageLength maximumMessageRatePerSecond name my first ivs chat room tags updateTime T The CLI does not return the messaging endpoint However it s easy to determine this There are only three options and they correspond to the region in which your chat room was created RegionEndpointus east wss edge ivschat us east amazonaws comus west wss edge ivschat us west amazonaws comeu west wss edge ivschat eu west amazonaws comTo retrieve a chat token from the CLI you can use the following command But hold off on generating that for now until we need it below because the token will expire pretty quickly To clarify the token itself is used to authorize a chat user expires and establish a session The default timeout for the session established via the token is minutes at which point a new session will need to be established via logic in your application more on this later on aws ivschat create chat token room identifier YOUR CHAT ROOM ARN user id A UNIQUE ID FOR THIS USER capabilities SEND MESSAGE Integrating ChatNow that we have a chat room let s build out a demo to see it in action As I mentioned above since the chat room requires a chat token we ll create a form to capture the token and the messaging endpoint lt form id settings form class needs validation novalidate gt lt div class mb row gt lt label for chat token class col sm col form label gt Chat Token lt label gt lt div class col sm gt lt input type text class form control id chat token required gt lt div gt lt div gt lt div class mb

gt lt div gt lt div gt lt div class mb row gt lt div class col sm offset sm gt lt button type submit class btn btn dark id submit settings disabled gt Submit lt button gt lt div gt lt div gt lt form gt You can generate your own token to plugin to this form via the console or the CLI methods shown above In your production applications you ll use an SDK to generate this token and refresh if necessary Here s how you might generate a token with the Node SDK reference docs import AWS from aws sdk const credentials new AWS Credentials accessKeyId process env ACCESS KEY secretAccessKey process env SECRET KEY const IvsChat new AWS Ivschat region us east credentials const createToken async let token const params roomIdentifier YOUR CHAT ARN userId UNIQUE USERID attributes capabilities

div gt lt div id chat input container gt lt div class input group gt lt input id chat input placeholder Message maxlength type text class form control gt lt button id submit chat class btn btn outline secondary gt Send lt button gt lt div gt lt div gt lt div gt We ll listen for the form submission and when that happens we can initialize the chat room WebSocket connection const endpoint document getElementById chat endpoint value const token document getElementById chat token value window chatConnection new WebSocket endpoint token All of the standard WebSocket events apply here For example to listen for incoming messages we use onmessage window chatConnection onmessage event gt parse the event data const data JSON parse event data append the incoming msg to the chat const msgHtml lt div class mb gt lt b class text primary gt data Attributes username lt b gt data Content lt div gt const chatContainer document getElementById chat chatContainer innerHTML msgHtml chatContainer scrollTop

msgInput document getElementById chat input const payload action SEND MESSAGE content stripHtml msgInput value attributes username username try window chatConnection send JSON stringify payload catch e console error e msgInput value msgInput focus The DemoLet s see our chat demo in action Use one of the methods we looked at above to get a chat token and use your chat room s messaging endpoint to login and give it a shot Check out the full source in the CodePen above to see the complete example SummaryIn this post we created our first Amazon IVS Chat room and learned how to integrate it into our live streaming application We ll switch gears in the next post and focus a bit more on broadcasting to our live stream If you have questions leave a comment or reach out to me on Twitter Image by

海外TECH	Engadget	SteelSeries Arena 9 review: Bringing 5.1 surround sound back to gaming PCs	https://www.engadget.com/steel-series-arena-9-review-gaming-speakers-130059973.html?src=rss	SteelSeries Arena review Bringing surround sound back to gaming PCsOnce upon a time desktop computer speakers actually mattered That was more than a decade ago long before gaming headsets filled the land and wireless Bluetooth headphones were any good In the early s more people also had actual desktops computers chained to desks so it was worth investing a bit in decent audio SteelSeries new Arena surround sound PC speakers reminds me of that era a time when I eagerly strung cables throughout my dorm room to connect Logitech s legendary Z surround sound speakers Apologies for anyone who lived near me I tried to keep things civil I swear Luckily it s not as tough to go surround sound today though it will still cost you a ton The Arena connect over USB so you don t have to worry about a specialized sound card and they feature wireless rear satellites which only need to be connected to power and each other There s no need to string anything to the front speakers That solves a huge pain point and it makes the Arena a far more viable option for the cable averse But is setting up a surround sound system worth it when gaming headphones are cheaper more immersive and kinder to your neighbors You ll have to decide that for yourself Assuming you do want to fill your room with speakers the Arena are notable for existing at all There aren t many PC alternatives today and they re mostly several years old like Logitech s Z released in You could of course set up an amplifier and connect whatever speakers you d like but anyone doing that probably isn t in the market for a self contained kit SteelSeries is striking a delicate balance between complexity and convenience for the most part I think the Arena is a success Devindra Hardawar EngadgetIn the box you ll find two front speakers both equipped with RGB lighting along their base and rears two wireless rear satellites a center channel a control module and a inch downward firing subwoofer The two way speakers don t exactly feel high end but their matte plastic casing should blend in with your keyboards and other PC components They re also far lighter than I expected which is rarely a good sign with audio gear My biggest gripe though comes down to the cabling The front and center speakers are hard wired to the rear of the subwoofer From what I can tell there s no easy way to replace those cables so you re stuck chucking the entire speaker if something goes wrong or getting very familiar with soldering I d much rather have removable cables instead of superfluous RGB lighting SteelSeriesI can understand why SteelSeries chose to include all of its audio inputs behind the subwoofer It gets more cables away from your desk and it s a smart place to house the amplifier and power components But that s also the only place with an aux connection so you ll need to string a long mm cable if you want to plug in any other devices Thankfully there s also Bluetooth support which gives you an easy way to wirelessly stream tunes when your computer is off For devices with digital audio like the PlayStation you can connect them via an optical cable there s also optical output port to pass sound to other gear Unfortunately the PS can only output sound two front speakers and the subwoofer over optical or USB You could upmix that audio across all of your speakers via the control pod but that would still just be simulated surround That s a shame for anyone who wants a system that can seamlessly work across their gaming systems and computers It s also doubly disappointing since the Logitech Z handled Dolby Digital and DTS surround processing from consoles and other devices all the way back in for just For the price I m surprised the Arena can t handle their own decoding Devindra Hardawar EngadgetAt least SteelSeries isn t trying to push the Arena as an ideal surround sound system for your home theater What s notable is that it s the first gaming speakers that work over a single USB connection Typically PC speakers either rely on three mm jacks or a digital connection like optical or coaxial Since it s relying on USB setup is simple even for laptop users who would typically have to get some sort of external sound card to use a system It only took a few minutes to get the Arena s front and center speakers hooked up to the subwoofer while the rears found homes on bookshelves behind my desk chair Those took a bit more effort since I had to find a nearby outlet to power the right rear speaker as well as string a cable across the floor to the left one If you ve got a large space you can also use an extra long RCA cable to connect those speakers On my desk the Arena looks cleaner than the huge KEF Q bookshelves I typically use Devindra Hardawar EngadgetI ll be honest though I care far more about sound quality than aesthetics when it comes to speakers Despite their relatively small size and average build quality the Arena sounds fantastic across games and movies The opening monster attack in Netflix s The Sea Beast rocked my office with explosions the sounds of giant waves and the rumble of a pissed off monster While playing Halo Infinite I felt fully immersed in every firefight so much so that I could clearly hear enemies creeping up behind me on the rear speakers One Halo Infinite match which equipped everyone with rocket launchers and skewers sounded like I was front row in a minute long fireworks show The Arena s are best when you can crank the volume as much as possible making them ill suited for apartments and smaller homes Do as I say not as I did They re peppy and energetic enough for games and films with large soundscapes I would have liked to see a larger subwoofer though A inch ported unit for a system this expensive just feels limiting I had to push the subwoofer s volume dial almost to its maximum to get a satisfying amount of low end punch A larger sub wouldn t need to work so hard Unfortunately the Arena s aren t as well suited to music something that seems to be the case for most gaming speakers They handled some of my typical speaker and headphone testing tracks just fine like Clint Mansell s Death is the Road to Awe from The Fountain as well as George Benson s “White Rabbit But the sound felt trapped by the small front boxes and the sub was far too boomy for my tastes Maybe my ears have been spoiled by my KEF speakers but I would have liked a larger sense of presence from the Arena Flipping on the simulated surround sound which plays music across all of the speakers just made the limitations of the entire system all the more clear I ll admit the Arena have a bit more depth than the Logitech Z s but they can t touch Klipsch s classic ProMedia speakers when it comes to music That system is legendary at this point it was originally released in which is when I bought it for college but the same exact hardware is still being sold today These complaints won t matter much if you re focused on gaming but discerning audiophiles would be better off with a bigger set that s better suited to tunes As much as I love great gaming headsets like SteelSeries own Arctis Pro and Nova Pro there s something more visceral about having speakers moving the air around you If you re a gamer looking for something a bit different and you have the money and space to spare the Arena could help you appreciate your favorite titles in entirely new ways But if you don t have the freedom to blast your nightly Halo Infinite runs at full volume it doesn t make sense to spend on PC surround sound speakers Get a decent system for music and stick with your headphones for gaming	2022-09-16 13:00:59
