Setting up SRT stream from a mobile phone via Larix Broadcaster to Vmix
Click OK.
A new input will be added to Vmix and if all parameters are configured correctly, your stream will appear in a couple of seconds. For this workflow, teams usually combine Paywall & access, Ingest & route, and 24/7 streaming channels.
9. Adjust the sound to send the sound of this Input to the Master.
Congratulations, you can now use your mobile phone as a Vmix camera from anywhere in the world!
In some cases it might be helpful to use Larix Talkback.
Larix Talkback is a technology for communication between a director and a cameraman.
In essense, this is just another SRT stream going from Vmix back to Larix.
So when is this useful?
Communication between the director and the operator
The remote operator conducts a report and, during the broadcast, receives sound from the director’s microphone into the headphones. Something among these lines : we are preparing for the broadcast, broadcast, change the angle, zoom in, move, adjust the microphone, etc.
Communication between the presenter in the studio and the remote correspondent
The remote correspondent hears the signal from the studio and is able to communicate live directly with the presenter: answer questions, conduct a dialogue.
Let’s begin :
1. Bus A B C D and master (M) are used to send sound output to different audio devices as well as to different streams (stream/SRT/NDI).
First, check that bus A is active:
Settings → Audio Outputs → A: Enabled → OK
You may need to reboot the Vmix to change the audio configuration. Don’t worry, your preset will be saved and loaded automatically. (Preset is the current Vmix configuration with all settings and added inputs).
2. Connect the director’s microphone
Add input → Audio input → select the microphone connected to your computer
Unmute sound from this Input:
1 — turn off the Master (M), because the director’s voice should not be heard by the viewer
2 — enable bus A to transmit microphone sound via SRT to Larix
The sound of any other Input will also be transmitted to Larix when bus A is enabled on it. If you want the remote operator to hear the broadcast on your device, send the broadcast sound to bus A
3. To set up Larix Talckback, let’s create a second SRT Callaba Cloud server. It will be completely similar to our first server, give it a different name and specify a different port. For example, 1936
Click “Save”
4. Open the “Info” of the new server. We will use these parameters to create an SRT broadcast from Vmix to Larix.
Leave this window open for now, we will need it very soon.
5. Open Vmix
Click Settings in the upper right corner
Go to the section output/NDI /SRT
For broadcasting to Larix, we will use output 2 (since the first is usually taken by the master broadcast).
The source value is not important, since only the audio stream will be sent back.
Click the gear icon to open Output 2 options
6. Let’s configure Output 2
Audio Channels: bus A (we will use bus A to broadcast the director’s microphone
Enable SRT: on
Type: Caller
Next, we will use the data of the second SRT Callaba Cloud server
Latency: 120 (your latency value)
Hostname: IP address of Callaba Cloud
Port: 1936
Stream ID: input/talkback/srt-stream-01 (publisher stream id of your SRT server)
By the way! You can always open the last used vmix preset with the Last button in the upper left corner
7. Now let’s move on to setting up Larix Talkback to get voice feedback from our studio. Let’s add a new connection:
Settings (gear icon) → Talkback → “+” icon
Create a name for this connection
URL: srt://adress:port of your server
Srt receiver mode: Caller
latency (msec): 120 (the value we calculated earlier)
streamid: output/talkback/srt-stream-01 (receiver stream id of your talkback SRT server)
Click “Save”
Make sure there is a check mark next to the new connection and return to camera mode “Settings” → “Back”
Check the status: “talkback ONLINE” means the connection is successful, the bus A sound from Vmix is transmitted to Larix and you can hear it on your mobile device.
That’s all! If you have any questions, please contact us at [email protected]. We will reply to you within 24 hours.
We wish you successful broadcasts, minimal latency and a wide communication channel!
