Open the stream manager
- Go to the Stream page on the dashboard
- Press the "New stream" button
- Make the selection on type of stream you want to add
- Based on the selection all options will appear for setup the stream
Note: If you made a mistake or want a add a different stream, close the popup and and start the same process again.
Select the stream type
Type: Input or output
Protocol: SRT or RTMP
Using SRT improves reliability and lowers the latency, the number of packet loss issues, and the jitter caused by timing issues. Compared to RTMP ingests that take 5 seconds, Kiswe reduced buffering to less than a second. The content streams are encrypted with SRT.
Provider: Regular or Premium
The premium provider has more options like combining SCTE markersbitrate, but The regular configuration is done automatically, while the premium requires manual setup. Here is the link to the regular and premium providers. If you wish to use the premium provider, please contact Kiswe.
Mode: Caller or Listener
A client connection is opened by the caller, while a server listening for incoming connections is started by listeren mode.
Configure your system
Name: stream name
Region: For less latency, choose the region closest to you
Host: The stream host
Port: The stream port
URL: The stream URL
Key: The stream key
Source port: Receiving port in Haivision
Destination port: Haivision output port
- Audio only: Set this to audio only if the stream is only audio
Turn this on if you have a simple stream with only audio and video channels. It helps us detect PID changes and automatically sets them up.
- Video: The video stream PID
- Audio - Nats: Nats audio stream PID
- Audio - Broadcast: Broadcast audio stream PID
- Audio - Director: Direction's audio (talkback) PID
Then turn this option on and fill in which PID's we need to pass through. This includes data streams (SMPTE and SCTE) as well as other audio streams.
If you create alternative audio tracks via the production tool's multitrack panel, you can specify a PID.
Is audio split into left and right (NAT & broadcast)? Turn it on if needed.
Different configurations can be used to re-encode streams
Video quality: Choose the quality at which the stream needs to be re-encoded
Keyframe: Specify the new keyframe to encrypt the stream
Audio codec (AC3 / AAC):
A lossy form of audio is stored in AC3 as part of the Dolby Digital audio compression technology. In addition to six discrete sound channels, it is most commonly used as a 5.1 channel configuration - five channels for normal-range speakers and one channel for low-frequency effects.
H264 Profile (high / low)
When encoding your video, H.264 profiles define what features are available to the encoder. The main profile is suitable for modern devices and web streaming. The high profile is suitable for long-term storage, PCs or Macs, Blu-ray authoring, etc.
CBR - Constant bitrate:
Streaming multimedia content on limited capacity channels is best done with CBR since it is the maximum bit rate that matters, not the average, so it maximizes the capacity.
- Passphrase: you can add a passphrase to protect streams. Note that it needs to be between 10-80 characters.
