  3. A Dacast account

1 – Video Tutorial: 


Check out this quick tutorial, and discover how you can quickly launch a live stream on your phone or tablet, with Larix Broadcaster Mobile App:

 

2 – Written tutorial: 

Larix Broadcaster is a free app for iOS and Android that you can use to live stream on the Dacast platform from your mobile device.

Note that Dacast supports iOS 13.1.1+ and Android 9+ so please check your device versions and update if required

Setup is easy.

To start off, once you open up the app (if you have just downloaded it), it will ask permission for it to use your camera, microphone, and location. All of these should be allowed.

Now once everything has been allowed, it will now take you straight away to the main screen which is essentially the camera capture part, as evidenced below. What you need to do is click on the screw icon (which is the settings part). To manually configure the encoder, make sure you follow our Live Encoder Configuration Guide and you should be good to go.

Now you will then be redirected to the settings page. What you can do is configure the settings first for the video:

What you can change is the video size based on the resolution that you wish to stream at. You can set it all the way up to the highest (1920X1088) or the lowest (176X144). Your upload speed should factor in the setting of this resolution:

For FPS, 30 fixed rate is the preferred frame per second. This should be fine moving forward.

Scroll all the way down then under the Encoder settings part, you can change the video bitrate accordingly (again based on your upload speed and as per our encoder settings guide):

For Keyframe Frequency, we recommend, setting it at 2 seconds. This should be fine moving forward.

Now everything will then be automatically saved, you can scroll back to the main Settings page and then click on Audio:

Now under the Audio parameters page all, you need to change are the following:

  • Channel count: Stereo
  • Sample Rate: 48000

Check out the Audio Parameters settings here:

These are again, based on our preferred encoder settings, and both should be set to these options respectively moving forward.

Next, scroll back to the main Settings page, then click on Advanced Options:

What you need to change from within this page are the following:

  • Frame Height
  • Frame Width

Again based on the resolution that you wish to stream at, choose in the corresponding frames per height and width. Please reference our encoder settings guide.

Now once everything has been changed you can now go straight to the Connections section so that you can manually configure your stream based on the Dacast live channel you will stream at:

Live Video Streaming - Larix Mobile Broadcaster - connections settings

Either clicking on New connections (to establish a one-time connection) or Manage connections (to save the given stream details moving forward) will work. Upon clicking you will be redirected to the stream settings part, this is called Outgoing connections:

In this example we chose a new connection:

These are based on the Dacast live channel encoder setup. Please input the following settings:

  • URL: Server/Stream Key (put a slash after the Server URL, then put the Stream key afterward.

In this example my Server URL on my Dacast account is 

  • rtmp://0736d04f-2f1c-b384-d89e-05ec581d0c52.dacastmmd.pri.lldns.net/dacastmmd

Then my Stream key on my Dacast account is 

  • 131a743dc3bf46eeab2537eba0a34c3a_3500

Put them together on the Larix app under URL as:

  • rtmp://0736d04f-2f1c-b384-d89e-05ec581d0c52.dacastmmd.pri.lldns.net/dacastmmd/131a743dc3bf46eeab2537eba0a34c3a_3500

Next, setup your credentials:

  • Login: Username
  • Password: Password

Now all of these pieces of information can be found under your Dacast live channel. 

Go to the General Tab, then click on Encoder Setup:

    Hello, I am new to all of this but I have been reading all of your articles. I want to live stream my church service from an Android tablet. You are suggesting broadcast me, but when I went to Google Play, they had pretty poor reviews oh, and were instead suggesting larix broadcaster. Does your service work with that particular software? Thanks, John
