Live Stream Details 

Use the Live Stream Details tab to view the live stream information.  In order to initiate a webcast, please refer to the Webcasting Producer Guide.

In the encoder output settings, configure the following information:

RTMP Primary URL  (mandatory) - This is the primary stream target URL for a webcast that uses an encoder. 

RTMP Secondary URL (optional) - This is the backup stream target URL. If it exists, your encoder will broadcast to both primary and backup endpoints for cases when redundancy is required.

RTMPS Primary URL - (RTMP over SSL) is the encrypted version of the RTMP protocol. This means you can send live content in an encrypted, secured and reliable way from your encoder to the Kaltura cloud.

RTMPS Secondary URL - (RTMP over SSL) is the encrypted backup endpoint. If it exists, your encoder will broadcast to both primary and backup endpoints for cases when redundancy is required.

Stream Name - This is the unique stream name that is used to identify your stream. Note that if you are broadcasting multiple bit-rate from your encoder, you will need to define several stream names with different suffixes (for example, myStream_1, myStream_2, etc.)

SIP User - This option is no longer in use. Use RTMP live streaming to broadcast with Kaltura Live from your video conferencing tool of choise. Check the following guidelines for Zoom and WebEx.

XML for FMLE - Download a configuration file for FMLE software.

SRT Ingestion

We also support Secure Reliable Transport (SRT) to ingest video stream for a live broadcast. This is an open source transport technology that optimizes streaming performance across unpredictable networks, such as the Internet. The SRT protocol brings several benefits in areas such as video quality, low latency, and end-to-end security. Use KMC or liveStream.get API call to get endpoints URLs and stream IDs for the primary and the backup SRT streams. To enable end to end AES-128 encryption for the stream, set the passphrase found in the liveStream object using the API.

Stream Configuration

• DVR On/Off (not configurable)
• Recording On/Off (not configurable)
• Transcoding Profile (not configurable)
• Preview Enable/Disable
  • If checked (enabled), the user must click on the Go Live button from either the Producer Application or from the KMC Real-Time Dashboard.
  • The default value is checked.
  • If the entry is live, this feature is disabled. 

Low Latency 

Historically, HLS has favored stream reliability over latency. Low-Latency HLS extends the protocol to enable low-latency video streaming while maintaining scalability. The new low-latency mode lowers video latencies over public networks into the range of standard television broadcasts.

To enable Low-Latency streaming check the Low Latency checkbox under the stream configuration section. Alternatively you can enable Low Latency from KMC or add the "lowlatency" admin tag to your live entry using the developer API. 

You can find more in our article Low latency streaming guidelines. 

Copy to Clipboard

The Primary and Backup details may be copied to clipboard. Click the copy icon next to the info you want to copy.
