Streams

Kiswe allows to add SRT & RTMP stream as ingest and output streams, for admin roles only.

RTMP

Kiswe Studio offers your admin the ability to create new  RTMP Ingests. They come as a combination of your team name and a random string generated by the platform.

SRT ingests & outputs

Using SRT as an ingest and output protocol, you can improve the rate of packet loss issues, the jitter caused by timing issues and your latency. Because of the improved reliability and latency, we have also reduced the local buffering in our Studio cloud to less than a second, compared to 5 seconds for RTMP ingests. With SRT also comes encryption of your valuable content streams.

You can

  • Create and manage your own SRT Inputs
    • In multiple regions
    • Mapping multiple audio-tracks for mixing in Studio ànd for passing through (see next section)
    • Add any SRT parameters for finetuning transmission metrics
  • Create and manage your own SRT Outputs

Input 

Options

  • Audio PID detection of stream PIDS when they change before event
  • SRT Mode (Caller - Listen)

Output

  • Constant bitrate

The rate at which a codec's output data should be consumed is constant. CBR is useful for streaming multimedia content on limited capacity channels since it is the maximum bit rate that matters, not the average, so CBR would be used to take advantage of all of the capacity.

  • Audio codec: AC3 / AAC

Known as Dolby Digital, AC3 is an audio compression technology that stores audio in a lossy form. It contains up to six discrete channels of sound and the most common use is associated with the 5.1 channel configuration - five channels for normal-range speakers and one channel for the extra low-frequency effects.

  • H264 Profile (high / low)

A H.264 profile defines what features the encoder can use when compressing your video. Main profile is used for modern devices and web streaming.  High profile for long-term storage, PCs or Macs, Blu-ray authoring, etc

  • Passthrough audio tracks with SRT

Map multiple audio-tracks from the ingest. In the 'create' or 'edit' dialogues, you can add your tracks and map their PIDs to one of the Studio mixer ingests, the Broadcast or the Nats feeds. Additionally, you can also specific tracks for passthrough. We are offering up to three passthrough tracks (Passthrough1, Passthrough2 and Passthrough3). 

You can have a single track being mapped to Broadcast ànd one of the Passthroughs.In the output SRT configuration, you can then map the different audio tracks available to PIDs in the output. You will have the Mixer audio track coming from your Studio event, ànd the different passthrough tracks available to you. In our current model, we are not checking whether the full passthrough mapping is correct. We assume you will validate this while combining inputs with outputs at time of creating your events.

Should you be faced with a conflict or missing mapping during or at the start of a live event, update your input and output settings appropriately, and remove/add those feeds back to your live event. That will update the entire end-to-end configuration.
