Is it possible to use a Chromecast device to be a 2nd external output from vMix?

Actually, I would like to be able to use vMix to transmitter to a Chromecast device over a network as an additional display or external display.

In other words, I would like to be able to "Cast" from vMix.

A common misconception regarding Chromecast is that a control device (eg a smartphone) transmits to a Chromecast device (eg inserted into a TV-set). But in fact the Chromecast device gets the content (eg a live video stream) directly from internet (via it's WiFi connection). The control device merely sends information to the Chromecast about what to play, and controls it (eg pause, play, volyme, etc).

In other words, vMix cannot "transmit" its output to a Chromecast device.

In theory someone could write a Chromecast app that plays video streamed to the network from vMix. Imagine the Chromecast works as an NDI player. But given NDI's heavy use of bandwith that's probably not a good idea. Furthermore I am not sure if Chromecast is powerful enough to manage an NDI stream. An app that controls the Chromecast app would also be needed.

To sum up, I don't think its worth pursuing. Sorry...

I stand corrected, and apologize.
Forgot about that (after I tried it year ago and thought it was useless).

I just did a quick check, casting from a laptop using the plugin for Chrome.

Works OK, but seemingly with reduced frame rate and heavy compression when video material is casted. It uses around 5 Mbps, measured by the laptops performance meter. If I played a YouTube video in my laptop, Chromecast switched over to its YouTube app and plays from the web instead of casting the video from my laptop, while I am still controlling it from Chrome.

Maybe it's not that difficult for Martin to implement streaming from vMix to Chromecast. Perhaps there is some stuff in the libraries he used for Web browser input.

Given the reduced quality it could be useful in some cases, for example for studio monitors (so the talents could see themselves. And for presenting still images, or animations when fps is not important. But not for serious stuff such as IMAG.

Probably no use to the original post as you cant do this nativly in vmix, and still need a 2nd output device to playout the video, but..

it works, kind of, ish..

Using out2, my PC's HDMI out. I fed that signal into a magewell capture dongle.
Captured the dongle image using VLC and streamed over my LAN.
On this same PC I grabbed the stream in Google chrome browser. Which sent the content of its webpage to my Chromecast..

The latency shown on the Chromecast monitor was terrible, and suffered low frame rates. As I'm using a PC that regularly handles 6 1080 sources, +effects +overlays & titles + recording etc with 2 video outputs I know it's not the PC being under powered.

Another test. This time using vmix program out over SDI, using a 'BMD duo card' again capturing and streaming via VLC.
The image on the chromecast was still very much delayed behind the original source and again with poor frame rates. The image quality was fair, and certainly viewable (except for the lower frame rates).

Watching the video in VLC and the video in chrome, i saw no noticeable delay. The delay must be between Google chrome and the Chromecast WiFi connection.

So, id say this isn't a good solution for displaying a Vmix 2nd output.

A.

The first step is to open the VLC Media Player on your PC. At that point, pick the file you want to watch.

Pause your video on the off chance that it begins playing naturally.

Now go back to your Chrome browser and tap on the casting tab. This uses your Chromecast so you can watch your VLC video.

Tap the drop-down bolt and select cast desktop.

Next, select your Chromecast gadget in the list.

You'll see a pop-up saying Chrome might want to share your screen. To permit it simply tap the share buttonin the lower right.

Next backpedal to your VLC media player and begin your picked video. Tap the play button and influence your video to full screen measure.

That is it. You're currently viewing your VLC media with your Google Chromecast device through the Chrome browser on your PC.
