• Main Sample: https://nanocosmos.github.io/webcaster/samples/index.html?streamName=[stream-name]
• Minimal Sample: https://nanocosmos.github.io/webcaster/samples/minimal/index.html?streamName=[stream-name]
• Screen Share: https://nanocosmos.github.io/webcaster/samples/screenshare/index.html?streamName=[stream-name]

Usage

The main sample showcases the lifecyle of the Webcaster, you can perform the following actions there:

• append your bintu stream name to one of the URLs
• configure stream properties in the editor WebcasterApiV6.Config
• click Create New Instance to create a new Webcaster instance with your configuration
• click startPreview to preview the MediaStream that will be streamed to our CDN
• click startBroadcast to start the ingest
• click stopBroadcast to stop the ingest
• click recover to restart the webcast with the same configuration
• click dispose to destroy the Webcaster instance
• click setMuted to mute the ingest

Configuration

All samples can be configured by the following URL query parameters:

• streamName
• ingestUrl
• serverUrl
• maxAudioBitrateBps
• transcodeAudioBitrateBps
• maxVideoBitrateBps
• maxEncodingFramerate

Config Interface

For explanation of the configuration options, please see the definition of the Config interface.

Main Sample

The main sample can be pre-configured through the webcasterconfig URL query parameter.
Please see this example link:

• In this example webcasterconfig encodes the following payload:

{"inputCfg":{"mediaStreamCfg":{"maxFramerate":30,"resolution":[640,480],"audioConstraints":{"autoGainControl":true,"channelCount":2,"echoCancellation":true,"noiseSuppression":true}},"broadcastCfg":{"transcodeAudioBitrateBps":128000,"maxAudioBitrateBps":128000,"maxVideoBitrateBps":500000,"maxEncodingFramerate":30}},"previewVideoElId":"preview","streamName":"[STREAM-NAME]","serverUrl":"https://bintu-webrtc.nanocosmos.de/p/webrtc"}

Configuration can be changed in the JSON editor under the WebcasterApiV6.Config section.
Changes to this config will be reflected into the location bar of the browser.

This means:

• you can change the settings, like resolution, bitrates, streamName etc
• you can then:
  • reload the window and changes will be persisted
  • or share your config by copying the URL from the location bar

Playback

You can play back your Webcaster ingests with our H5Live Player.

The main sample from preceding includes a side-by-side player for your convenience when testing. To create a shareable player link, append the stream name to our player demo URL:

• Player URL: https://demo.nanocosmos.de/nanoplayer/release/nanoplayer.html?entry.rtmp.streamname=[stream-name]
