Set up an SRT stream using caller and listener modes
When you're configuring an SRT stream on Pearl Mini, you can also adjust the recovery bandwidth overhead
using the Admin panel. This setting defines how much of the stream's total bandwidth is dedicated for the
exchange of SRT control and recovery packets between the source and destination. Ensure that the total SRT
stream bitrate (i.e. the bandwidth required for the stream plus the recovery bandwidth overhead) is less than the
network bandwidth you have available.
Set up Pearl Mini as a streaming source in caller/listener mode using the Admin panel
1. Log in to the Admin panel as admin, see
Connect to the Admin panel
.
2. From the Channel(s) menu, select the channel and click Streaming. The Streaming configuration page
opens.
3. Click New stream and choose SRT push. The new stream with the default name
Stream 1 is created.
4. Click the stream name to see the stream settings.
5. In the Connection mode field, select if this Pearl Mini is the caller or a listener.
a. If Caller is selected, do the following:
i. In the URL field, enter the IP address of the SRT destination (decoder) using the format
srt://
provided by the CDN, media server, or another SRT decoder device.
ii. (Optional) In the Source port field, enter the port number that this Pearl Mini should use for
SRT traffic.
b. If Listener is selected, enter the Port number that this Pearl Mini should use for SRT traffic. See
Network ports used by Pearl Mini
to determine available ports.
6. (Optional) In the Stream ID field, enter a unique name for this stream.
7. (Optional) Check Encryption and choose the AES key length if the SRT destination requires AES
encryption. These settings must match the encryption settings of the destination device, see
Set AES
encryption and a passphrase for SRT
.
8. (Optional) If the SRT destination has a required security Passphrase along with the AES encryption, you
can enter that here.
9. (Optional) In the Latency field adjust the amount of latency to apply to the stream. The default value is 125
ms.
We recommend using the default latency and recovery bandwidth overhead values for an
initial test stream. After you perform a test stream, you can determine the Quality of Service
(QoS) and calculate the latency requirements. To set the SRT stream latency, see
Adjust
latency and view the SRT stream status
.
10. (Optional) In the Recovery bandwidth overhead field, adjust the % value of the bandwidth that's
dedicated for SRT control and recovery packets. The default value is 25%.
11. (Optional) Rename the stream. Click the current name and enter a different name, then press Enter.
Refresh your browser if the new stream name doesn't immediately display.
