This is really interesting and an absolute game changer. Hopefully it kills Chromecast. Like others, I only knew of Matter as a home automation consortium, that they've worked out a casting open standard and will be pushing that is amazing. I look forward to seeing it adopted. That said, apparently Matter certification is expensive and everything I've seen using Thread thus far drops connection a lot so it may take a while.

I've seen Thread mentioned twice so far, but I don't think I've heard of it, and apparently a name like that makes it impossible to find any information about it. Do you have a link plz?
Sure thing: https://www.threadgroup.org/What-is-Thread/Thread-Benefits
Basically Matter over Thread is the new Zigbee.
What's wrong with miracast? Almost every device sold these days has some kind of radio, but no way to talk to each other. Releasing a new standard every few years won't help much.
I don't know the specifics of Miracast, but my impression was that it is specifically used to cast a video stream from one device to another device. That is sometimes useful, but not what I typically use my Chromecast for.
The most useful feature of my Chromecast is the ability to be logged into Plex/Netflix/HBO/Spotify/YouTube/etc on my (or my guest's) mobile device, and effectively send a link and a (probably ephemeral) token to the Chromecast so that it can stream directly from the server to the Chromecast without my mobile device spending battery power and bandwidth being a middle-man.
And I assume the difficult part here is down to copyright reasons. Most of those streaming sites already limit the number of devices you can permit to stream content (which sucks, but is besides the point), so my impression is that they need to have some kind of under-the-table agreement with the Chromecast/Roku/Firestick/Apple TV/etc. folks to ensure that the device will correctly validate the credentials, not save any of the content, and properly dispose of everything when it's done. And I assume Google has similar talks about when a device on the network is allowed to be listed as a casting device to apps.
Does Miracast already handle this?
Isn't Miracast for sending video data? The thing I like about Chromecast is that the phone or remote app just tells the Chromecast where to load the media directly from, and then only sends playback control commands. That makes it a lot lighter resource wise because you don't need to proxy the stream through a device like a phone that wants to go to sleep to save battery.
The company says services like Plex, Pluto TV, Sling TV, Starz, and ZDF will introduce support later this year.
I always had the impression that plex was really slow when it comes to implementing new features. I'm definitely looking forward to a chromecast alternative though. Being locked into googles DNS gives me problems due to it prohibiting streaming from my local server via hostname.
I really hope it will be implemented in Jellyfin as well since I can't get my installation to work with Chromecast at all (most likely again due to the DNS issue)
Being locked into googles DNS gives me problems
I solved that by adding an 8.8.8.8 ip to my pihole interface. Because of how TCP/IP works, this has the fewest hops and is, therefore, the one to be used. I'm blocking all outbound DNS traffic for good measure.
By adding do you mean blocking it in pi-hole or somehow redirecting it to your pi-hole dns server?
I currently have it blocked in my router and can confirm this by trying to ping 8.8.8.8 without any response. If you mean redirecting to your pi-hole I would really like to know how to do it
I didn't add it to any lists, but to the network interface itself. You know the output of ip a? The one pihole listens on (wg0 in my case, because wireguard) has something like, say, 10.0.0.1, but also 8.8.8.8. So when a DNS packet is spit out by chromecast to go to 8.8.8.8 UDP port 53 - my pihole happily answers that request. You could also do a separate unbound instance on a new virtual interface with a quad8 ip and just forward everything to pihole, if you fancy.
"Matter Casting" is not a very catchy name
Also Matter is the smart home interop standard. Seems close enough for some confusion in what Matter compatible means on a device.
It's the same Matter afaik, but yeah, I had forgotten about the interop standard and originally thought "Matter" was specific to this casting spec.
Oh right, that makes sense. I was only thinking of Matter as serving low bandwidth devices but it also runs over WiFi and ethernet so I guess it can do video for security cameras etc. and evidently Casting audio and video also.
I hope to see Jellyfin support this too (Plex is already getting support apparently) and hopefully it will work desktop-to-desktop and not just between streaming devices and phones.
Although it's probably not massively needed as Jellyfin can already control remote devices.
If something could cast from one of my devices to another of my devices using the cast button, that's all I want. I can strap one of those devices to my TV and be golden.
