FlowCaster Quick Start for SRT (Secure Reliable Transport). This article explains how to set up and test the FlowCaster output with freely available player tools.
FlowCaster Quick Start - SRT
Here is a quick start guide on how to enable FlowCaster’s SRT output:
Download and install FlowCaster
Download and install VLC (on the same machine to start with)
Determine your computer’s IP address (Windows Terminal: ipconfig, macOS/Linux Terminal: ifconfig or Control Panel)
Run your creative software (Adobe Premiere in this example)
Open the FlowCaster configuration dialog. For Premiere, the menu Preferences | Playback. For Avid Media Composer, the menu Tools | Hardware Output, when enabled.
Click on the Preferences | Playback menu.
In the Adobe Preferences dialog, enable the checkbox next to FlowCaster Transmitter, and select FlowCaster Transmitter as your Audio Device. Click the Setup link next to FlowCaster Transmitter to bring up the FlowCaster configuration dialog.
Set up the dialog as shown above
- Transmit Type: SRT Listener
- URL: srt://<your ip>:5000
- Latency: 90
- Encryption: None
- Password: Empty
- User: Empty
- Stream: 0
- Compression: h.264/AVC1
- Structure: IPPP
- Bit Rate: 2500
- Audio Mode: Stereo
There are just to get the initial output tested. You can modify them as you need for your final workflow, once these tests are complete. Click Ok on the FlowCaster Config and Adobe Preferences and you will be transmitting Premiere’s output.
To receive the signal you will need VLC version 3.0.12 or greater to support SRT. Run VLC and select the menu Media | Open Network Stream.
This will bring up the Network Open Media dialog
in the network URL text box and click Play and VLC will start receiving the SRT stream from Premiere.
If you have the FlowCaster App installed on your phone you can receive the SRT there as well. Close VLC and open FlowCaster on your phone. After logging in, select Play an SRT Stream.
This will bring up the configuration screen.
Select Caller and set the Address to <your ip> and the Caller’s Port to 5000. Click Play to start receiving the SRT stream
Once you have FlowCaster set up, configuring it for various scenarios will be a combination of transmission type, address and port, to match the sender and receiver. Here are some of the basic rules to follow:
- If FlowCaster is a Listener, then the receiver must be a Caller
- If FlowCaster is a Caller, then the receiver must be a Listener
- If FlowCaster is in Rendezvous mode, the receiver must also be in Rendezvous mode, and the internet facing IP addresses must be used
- To get the internet facing IP address, go to https://www.netxfer.com/action.php?action=getmyip&format=human on both machines
- VLC only supports Caller mode (so FlowCaster must be a receiver)
- Whoever is the Listener must use a local address on the machine to listen on
- The Caller’s address and port should match the Listener’s address and port
- Rendezvous address will be the ones outside your firewall, on the actual network/internet
