The Wowza Streaming Cloud service provides quite a lot of options to simplify your streaming structure, enabling you to stream high-quality video to audiences of any measurement, on any gadget, wherever. As a result of Wowza Streaming Cloud is constructed on the Wowza Streaming Engine software program, you’ll be able to profit from most of the identical options, however with minimal configuration.

With new superior options and performance being up to date usually in Wowza Streaming Cloud, we’d wish to share 5 workflows that you might have thought had been solely accessible in Streaming Engine, however you may be utilizing now in Streaming Cloud.

1. WebRTC Ingest and Playback

With Wowza Streaming Cloud, you’ll be able to seize video out of your browser and ship a WebRTC stream with all main browsers that help the WebRTC APIs. When you join and begin the stream, you should use the hosted pages offered by Streaming Cloud to each publish and play again WebRTC streams with minimal configuration.

It’s necessary to take into account that an end-to finish WebRTC workflow implies that Wowza Streaming Cloud will ingest a single-bitrate WebRTC supply stream and ship it straight from the transcoder for WebRTC playback. That makes it a passthrough stream the place no transcoding is carried out. This workflow is finest suited to stay stream broadcasts with fewer than 300 viewers. For audiences bigger than 300, we recommend you as a substitute use Streaming Cloud’s WebRTC to HLS workflow, which can ingest a WebRTC video from a browser, course of the stream in its adaptive bitrate transcoder and use the CDN to scale and ship your stream over HLS.

2. Stream Scheduler

Scheduling your streams can simplify your workflow, prevent a major quantity time, and hold your viewers knowledgeable of upcoming occasions. In the event you or your group stream regularly, configuring every particular person stream can shortly add as much as a number of hours of valuable time every week. Configuring a stream schedule is helpful in case you have a every day streaming occasion and in addition prevents any streams and transcoders from being left working when an occasion has ended. Wowza Streaming Cloud permits you to schedule the beginning and cease of a stream at a predetermined date and time with the choice to configure a repeating schedule.

Further scheduling choices embody streaming to stream targets like Fb Reside, YouTube Reside, or different social media websites; configuring your schedule utilizing the Streaming Cloud REST API; and viewing the high-level particulars of all of your schedules on the Schedules web page.

3. Metadata for Interactive Streams

Timed metadata is custom-made information used to supply data at a really particular time limit throughout a stream. The timed metadata flows by a server to the shopper the place, throughout playback, the timecode serves as a cue level to invoke some motion on the information. Metadata consists of information a few stream that’s synchronized to video frames by a timestamp and permits you to add cued interactivity comparable to textual content overlays, bidding, betting, GPS information, or question-and-answer video games to a stay stream. The Wowza Streaming Cloud REST API permits you to ingest AMF information that’s embedded into an RTMP stream from supply encoders, cameras, or Wowza Streaming Engine. That stated, the AMF information should be transformed to ID3 tags to ensure that the metadata to work in HLS playback. When a participant that helps ID3 tags receives an HLS stream, it could pay attention for and course of the metadata.

Listed below are the steps:

Wowza WSC stay metadata injection

1. Create Wowza Streaming Cloud stay Stream by way of the Relaxation API
2. Allow metadata processing
3. Change default transcoder chunk measurement
4. Take away the stream smoother and cut back some inside buffers
5. Begin stay stream (non-compulsory — stream will auto begin if you happen to don’t do that)
6. Begin inbound stream
7. Name metadata API
8. Confirm in output HLS

For full step-by-step directions and code samples for injecting metadata right into a stream, go to Wowza’s GitHub web page.

4. Stream a File

You might be shocked to be taught that Wowza Streaming Cloud permits you to stream .mp3 and H.264-encoded .mp4 and .flv information, however the information should be hosted on an internet server, Google Storage, or Amazon S3 bucket. You’ll be able to simply configure this in both the Streaming Cloud Supervisor or Streaming Cloud Relaxation API.

To stream a file utilizing the Cloud UI, signal into the Cloud Supervisor, create a brand new stream, then choose Stream from File because the supply on the Video Supply and Transcoder Settings web page.

When you begin the stay stream or transcoder, Wowza Streaming Cloud will obtain the file from the desired URL after which begin the stream. We do counsel including a buffer of 10–15 seconds to the top of the file to make sure that the stream doesn’t reduce off prematurely.

You too can stream a file utilizing the Streaming Cloud REST API, however be aware that this characteristic is barely accessible in model 1.5 of the REST API and later. In each the Cloud UI and Streaming Cloud REST API workflow, Wowza provides superior transcoder properties when streaming a file comparable to enjoying a file on a loop or making a stream schedule to instruct Streaming Cloud to start streaming the file at a sure date and time.

5.  Webhooks Notification

In January 2021, the Wowza Streaming Cloud crew introduced a brand new performance permitting you to make use of webhooks to combine with different functions to streamline or automate your workflows. In the event you’re not acquainted, webhooks are notifications that Streaming Cloud sends when particular occasions occur in your Wowza Streaming Cloud account.

Sometimes, with the intention to decide when an occasion has occurred, you’d use the REST API to ballot your account. For instance, chances are you’ll wish to know when a recording is uploaded and accessible, when a transcoder has began, or when your stream is stay. Typically, it might require a number of polling makes an attempt to find out the occasion standing. However with webhooks, Wowza pushes notifications to you, eliminating the necessity to dedicate code and bandwidth to sending repeated REST API requests. As an alternative, you’re in a position to create a webhook endpoint that listens for the occasion notification after which your software can reply to the notification when it’s obtained.

To obtain occasion notifications, you could allow webhooks on your Streaming Cloud account and create a webhook endpoint. Wowza Streaming Cloud sends webhook occasions for transcoder and recording actions in JSON format by a POST request.

Right here is an instance of a webhook notification when a transcoder has stopped.

{
  "model": 1.0,
  "occasion": "cease.full",
  "event_id": "9be47e2a-b5ff-492a-a291-c7be79c060ba",
  "event_time": 1588864470.813283,
  "object_type": "transcoder",
  "object_id": "pl3fff7q",
  "object_data": {
    "uptime_id": 7cb5yfnx
  }

Please see our documentation on receiving occasion notifications with webhooks to discover ways to allow webhooks on your Wowza Streaming Cloud account and obtain occasion notifications.

Conclusion

That concludes our record of the Wowza Streaming Cloud workflows try to be utilizing. We encourage you to experiment with some or all as a simple method to simplify your streaming structure. Updates to the Wowza Streaming Cloud UI and API are posted within the What’s New panel of the Wowza Streaming Cloud UI.
