The lag is terrible with mirroring. Apple TV won't be viable for gaming until the game is played on the box itself and there is a low-latency controller.
Yes, this. It is really stretching it to say that you can effectively "game" on your TV when airshare'ing from your iPad /iPhone to your Apple TV. It sucks.
Similarly, I've never understood the purpose of ChromeCast. The lag makes it completely unusable for video (I'm getting ~1 frame / 3 seconds), making it a glorified radio with cellphone/laptop remotes.
I think people confuse the ChromeCast tab/screen mirroring (which is slow and laggy) and ChromeCast DIAL/casting from apps like Netflix which actually just sends a URL to the Chromecast to stream
Yeah, ChromeCast is a great product and a major marketing failure. Hardly anybody (even techies!!) understands that it is about competing with Apple TV (and now Amazon Fire TV) in the streaming market, not sending arbitrary stuff from the browser to your TV. Honestly, they should have launched without any of the confusing and crappy tab-casting functionality at all and probably called it something different than ChromeCast. The thing has (ridiculously cheaply) solved my entire internet-television-entertainment problem but I've literally never once used it for a browser tab.
as a techie that doesn't know how to use ChromeCast the way it should be used (as you've mentioned) would you mind enlightening me? How, exactly do you use it if not with the tab-casting?
I don't understand why Google are so bad at advertising and marketing. Probably the only reason Chrome itself took off was that they put a big ad for it on the Google homepage. Maybe they should now switch that ad and advertise something else?
Okay, that's great. But I don't use Netflix at all. I'd like to watch something from VLC, but apparently the plug in that enabled that was killed. Google's so simple its stupid makes it impossible for me to find out how the thing actually works and why I can't try to configure it to work any better.
AllCast (one of the more notable apps that supports streaming from local apps like VLC) got its Chromecast support back once the official SDK (finally) came out:
I believe there is something more nuanced going on with Chromecast "casting" performance.
Netflix is fast obviously because you are just telling the chromecast to stream netflix itself, not "casting" it to chromecast. Same goes with youtube.
However "casting" performance for me is even worse than the described .3fps on my Chromebook Pixel that isn't running ChromeOS. And my LAN is fast enough to use mplayer over ssh/x-forwarding... Trying chrome tab casting in Debian on a Chromebook Pixel burns the Pixel up, with it being very obvious that the Pixel is the bottleneck.
Trying to video encode the "cast" tab without using hardware support maybe? I'm not sure, I haven't really investigated it further.
Is Chrome actually decoding the file then reencoding it / pushing raw video frames, or is it just streaming the file to the Chromecast? I suspect the later.
Tried it myself. Chrome plays the video fine itself. Trying to cast that tab to Chromecast has the CPU usage on the casting computer spike way up. This is not a network bandwidth issue.
Incidentally I've just discovered that my Roku can have local videos streamed to it from my S3. It works flawlessly.
I just bought a chromecast now it's finally out in the UK. Streaming local video from my dlna server over wifi has been a total pleasure and works perfectly. Iplayer, youtube, any other html5 video I throw at it just works. What are you trying to do with it that gets that kind of lag? The only thing I've found which reduces framerate at all is the experimental fullscreen casting.
This is something I can't get my head round. I have a NAS which I sometimes stream stuff from my xbox 360 from. With chromecast do I need any other device for that to work. Or does it go NAS > Phone/Laptop > Chromecast. Or NAS > Chromecast.
You need to upgrade your router. I was using a cheapo D-Link router when I first got my ChromeCast and the connection was awful. Range to laptops and devices was terrible and the connection always dropped. I bought an ASUS router for $150 and life is incredibly easier. I can stream HD content from 40-50ft away across 3 bedrooms without any issues.
I'm confused: are you talking about wifi range (presumably fixable by using a WAP that's better than the one built into your router) or the bandwidth of the router itself? Only asking because ISTM a decent WAP is much cheaper than $150...
It's not necessarily bandwidth or range. Some of it can just be the quality of the router implementation. I remember having lots of trouble with a Chromecast (discovery issues, losing connections and other issues) and I couldn't figure out what was going on, especially since I had a brand-spanking new high-power access point.
But I wasn't using my new access point as a router. For unrelated reasons, I replaced the 10+ year-old router with something newer and the Chromecast started working flawlessly even though I hadn't changed anything on the wireless side.
OK so it's not the WAP, but I still think we could differentiate between an ethernet switch upgrade (for local problems i.e. with content streamed from one device to another) and a router upgrade (for upstream problems: NAT issues maybe?). Routers have switch functionality built-in, but since you were using a really old one you might have tried sticking a cheap switch between the router and your local network before upgrading. Anyway, I think the blanket "You need to upgrade your router." advice is unwarranted.
Have you tried the 'Videostream' app for the Chrome browser? Works flawlessly for me for playing local videos (although only mp4 right now). They also have an Android app so you can use your phone/tablet as a remote control.
That is odd. On mine on a poor connection it works like youtube -- it pauses for buffering. But it plays smoothly when it's not paused for buffering...
To the people saying they haven't had a problem with it: Have you ever tried to play an action game via mirroring on Apple TV? The lag is short enough that it might be acceptable for turn based games, but playing, e.g. Real Racing (which I have) is a terrible experience.
This is an AirPlay issue, right? For example, when I go to pause a song that is being AirPlayed to my Airport Express, there is a noticable delay before the song stops playing.
It works fine for me, and if I remember correctly the people having a problem with lag had their ATV connected via RJ-45 and switching to wifi fixed it.
