Hi,

we would really like to provide some hardware for a bunch of clients to securely connect to our VMIX session.

We would really like to use some Android Tablets for that purpose. I did some testing today but found out that all of our test tablets (Huawei, Samsung, Yestel) only connect at 640x380, allthough the camera is much more powerfull to even do full HD (I know that VMIX call is limited to 1280x720).

I did a test with the WebRTC testing site (https://test.webrtc.org/) and it showed up all resolutions of up to 1920x1080 as available. Only on VMIX call I get only 640x380.

So what is the problem here?


Cheers

pro.

OK - I found this in the vmixcall.js:

Quote:
if (navigator.userAgent.match(/Android/i)) {
// constraints = {
// audio: true,
// video: {
// width: { min: 180, max: 640 },
// height: { min: 180, max: 640 },
// frameRate: 30
// }
// }
constraints = {
audio: true,
video: { width: 640, height: 360 }
}
t.mobile = true;
}


That means that vmixcall limits all Android connections to 640x360!

Why? We need better resolutions from our Android devices - all of the cameras have at least 1920x1080.

Could you please change that that we can get 1280x720 from Android devices?

Come on - we are in the Corona restrictions. We will need a modern,high-quality VMIX-Call more that ever. Please change that useless restriction.


Anyone from the VMIX Team?

Cheers

This means frame rates will be a bit lower and why we set the resolution to 640x360 by default.

iPhones/iPads on the other hand use a hardware encoder and can send 720p quite easily.

Just to clarify, Android devices have much the same hardware encoding capabilities as iOS devices and most apps use these capabilities (such as the built in recording apps for 4K video and apps like Larix Broadcaster). However Chrome and FireFox apps on Android do not take advantage of this functionality for WebRTC specifically, though it is possible they may in the future.


Anyone knows if the future perhaps has arrived?

Yes and no. If you use the "Desktop site" feature" in Chrome, you can bypass the limitation. I just tested it and successfully got 720p30 on a OnePlus 8T
