Live Stream Setup page in Wowza Video

This article introduces the different parts of the Live Stream Setup page to help you find your way around the Wowza Video user interface.

The Live Stream Setup page acts as a wizard that helps you to create your live stream.


Live Stream Setup page

This page includes 5 tabs that you can navigate through in order to create a live stream.

Live Stream Setup tab

  • Live Stream Name – A short, descriptive identifier for the stream that differentiates it from other streams. The Live Stream Name is required and can't be more than 200 characters in length. It doesn't have to be unique.
  • Broadcast Location – The geographic region where Wowza Video transcodes and processes your live stream. Select a Broadcast Location that:
    • Supports 4K streaming (3840x2160 resolution), if you want to use it,
    • Supports the billing mode you're using, pay as you go or 24x7, and
    • Is as close as possible to where your stream will originate.
  • 24x7 streams can't be recorded.
  • Asia Pacific (Taiwan), EU (Belgium), US Central (Iowa), and US East (South Carolina) don't allocate dedicated GPU resources to 4K, 24x7 streams. As a result, running 4K streams in the 24x7 billing mode at these locations is not recommended.
  • For information about the features available at each location, see the technical article Wowza Video broadcast location features.
  • For information about 24x7 and passthrough subscriptions, see the Wowza Video 24x7 streaming plans page.
  • The Broadcast Location can only be changed by editing it on the Transcoder Setup tab of the stream's transcoder detail page. For details, see the user guide topic Edit a transcoder's settings, outputs, or targets.

Video Source and Encoder tab

  • Camera / Encoder – A source for your stream:
    • Wowza Streaming EngineTM – Wowza Streaming Engine can push streams Wowza Video to deliver streams through Wowza Video output targets.
    • Wowza ClearCasterTM – An appliance for broadcast-quality, reliable streaming.
  • Wowza GoCoderTM – A mobile encoding app for iOS and Android devices.
  • Web Browser (WebRTC) – WebRTC is an open-source project that enables real-time communication of audio, video, and data in web browsers and apps. This is for capture via webcams with no encoder required.
  • Works with WowzaTM partner – Choose a professional encoder or IP camera from a Works with Wowza partner, including Axis, NewTek, Sony, Telestream, or Teradek.
  • IP Camera – Any IP camera that supports RTSP and H.264.
  • Other RTMP – Any encoder that supports RTMP and H.264.
  • Other RTSP – Any encoder that supports RTSP and H.264.
  • Other SRT – SRT is an open source video transport protocol that is designed to deliver secure, high-quality, low latency live streams over unpredictable network conditions.
  • Other UDP – UDP is a connectionless protocol that makes it easier to transmit information quickly, but is also more prone to network issues, packet loss, and packets arriving out of order.
  • Stream from File – A .mp3 or H.264-encoded .mp4 or .flv file hosted in a publicly accessible location on a web server, Google Storage, or Amazon S3 bucket.
  • Live Stream Type – Live streams can be Adaptive bitrate or Passthrough. An Adaptive bitrate stream generates multiple renditions of the source video, at different bitrates, which means the playback is optimized for all device capabilities and bandwidth. A Passthrough stream sends the source video directly to the hosted page or other target without performing transcoding.

If your subscription plan covers passthrough streaming, select whether you want to create a passthrough or adaptive bitrate live steam.

Important: The Live Stream Type can't be changed after the live stream is created.
  • Billing Mode – If your subscription plan covers 24x7 billing, choose whether you want to run the stream in Pay as you go or 24x7 mode. 24x7 is for always on, whereas, Pay as you go is for events.
  • 24x7 streams run until they are stopped either manually or by using a schedule. They do not automatically stop after the transcoder has been idle for 20 minutes.
  • 24x7 streams can't be recorded.
  • 24x7 streams don't support 4K resolution.
  • The Billing Mode can't be changed after the live stream is created.
  • Adaptive bitrate or Passthrough – For Other RTMP or Other RTSP, specify whether the encoder will Push the stream to Wowza Video or whether Wowza Video needs to Pull the stream to the transcoder.
  • Push or Pull – For Other RTMP push streams, select Push directly to Wowza Video to send the stream directly to the transcoder at your Broadcast Location. Alternatively, select Push to a stream source to route the stream through a CDN endpoint.
  • Source URL – For IP cameras, including IP cameras from Works with Wowza partners, and for RTMP and RTSP pull streams, enter the device's web address. Consult the device's documentation for the syntax of the stream address and enter it in the Source URL field.
Note: By default, Wowza Video uses TCP port 1935 for RTMP streaming and TCP port 554 for RTSP streaming. If you don't use the default port, be sure to indicate that in the source URL.

For .mp3, .mp4, and .flv files, enter the URL where the file is located. The URL must be publicly accessible. Supported protocols are http, https, gs, and s3.

  • Reduced Latency – If the Delivery Protocol is HLS, you can create a reduced-latency stream. Reduced-latency streams use modified transcoder buffer settings and send smaller video packets to players from Wowza CDN on Fastly. This can reduce latency to as little as 10 seconds, but it also creates additional network overhead. If the client doesn't have enough bandwidth, playback may stall. Also, playback may be affected on some older devices. Select Yes, create an HLS stream with reduced latency only if your viewers experience unacceptably long latency while watching your live stream over Wowza CDN on Fastly. 
  • The reduced latency option can't be changed on the Video Source and Transcoder page. Adjust the incoming buffer size and turn on the sort packet buffer on the live stream's transcoder detail page (see the user guide topic Edit a transcoder's settings, outputs, or targets).
  • Real-Time streaming at scale provides half-second latency to all your viewers, no matter where they are and may be an option for you if latency is important. Real-time streaming is perfect for interactive use cases like video chats, auctions, esports, fitness, e-commerce, gambling, and more.
  • Aspect Ratio – The aspect ratio and pixel dimensions, or frame size, of the source video. Choosing the correct aspect ratio and dimensions ensures that the video won't be distorted, squeezed, or cropped when it's played.

The higher the resolution of the incoming video, the more bitrate renditions Wowza Video generates. A bitrate rendition is a version of the live stream at a specific frame size and bitrate, such as 640x360 pixels at 1200Kbps. Wowza Video creates multiple bitrate renditions, based on the resolution of the source video, to offer the best possible playback experience given a viewer's device and bandwidth. The following tables show how many bitrate renditions Wowza Video generates.


Source Video Frame Size Number of Bitrate Renditions
≤ 3840 x 2160 7
≤ 1920 x 1080 6
≤ 1280 x 720 5
≤ 848 x 480 4
≤ 640 x 360 3
≤ 512 x 288 No transcoding. One output rendition.


Source Video Frame Size Number of Bitrate Renditions
≤ 768 x 576 4
≤ 640 x 480 3
≤ 384 x 288 No transcoding. One output rendition.

  • Save to Asset Management– A recording is a MP4 file of your live stream that you can download and save locally. Use this option to save a recording as an asset to the Asset Manager. We also save the HLS for VOD replay.
Note: Recordings incur storage costs. For more information about recording streams and usage, see the user guide topic Record live streams and transcoders.
  • Closed Captions – Wowza Video can receive closed caption data with your source stream so that captions appear when the stream is played using the HLS protocol. Choose the type of caption your video source is sending to Wowza Video: CEA-608 (digital), Action Message Format (AMF) onTextData, or CEA-608 (digital) and onTextData. To omit captions from playback, leave the closed captioning option set at None.
Note: Wowza Video supports only the digital CEA-608 portion of the CEA-708 closed captioning standard.
  • Source Security – By default, Wowza Video secures Wowza GoCoder, Wowza ClearCaster, Other RTMP / Push directly to Wowza Video, and Other RTSP / Push Stream connections by requiring a source username and password for authentication. Select Disable authentication if you don't want to use authentication with your video source connection. Usernames and passwords can contain only upper and lowercase letters; numbers; and the period (.), underscore (_), and hyphen (-) characters. No other special characters can be used.

Playback Settings tab

Playback settings are used by the player on your Wowza Video hosted webpage. If you use a different player or play streams in Safari using the HLS playback URL, playback settings are disregarded.

  • Player – The player you want to use for your live stream:
    • Wowza Video subscribers
      • Wowza Flowplayer – Wowza Flowplayer is the only player option. This player leverages an easy-to-use, commercial-grade player which you can customize if you embed it into your site.
    • Other subscribers
      • Original HTML5 player – A HTML5-based player that plays HLS and supports closed captions.
      • Wowza Player – Wowza™ Player is a lightweight HTML5 player that plays HLS and doesn't support closed captions.
        Note: In order to choose Wowza Player, Closed Captions must be None. If necessary, go to Video Source and Transcoder Settings to set the Closed Captions option.
Note: If you are an upgrade customer and have live streams that use our older players, you can update your existing streams to use Wowza Flowplayer, but you won't be able to change them back later.
  • Player Width – The width of the player can be either fixed or variable. If you choose Responsive, the player's width adjusts for the device on which it's being viewed. If you choose Fixed Width, enter a width, in pixels. The height is calculated automatically based on the aspect ratio of the video source. The dimensions, whether fixed or responsive, are used in the player embed code.
Note: For a fixed-width player, we recommend a minimum width of 365 pixels. If you need a smaller player, use a responsive player instead of a fixed-width player.
  • Countdown Clock – (Optional) A countdown clock that appears in the player before the stream begins. If you include a countdown clock, provide the date and time zone of the event.
  • With the original HTML5 player, if you display both a poster image and a countdown clock, the poster image appears behind the clock.
  • With the original HTML5 player, the countdown clock doesn't appear in the Flash fallback player.
  • Video Poster Image – (Optional) A poster image to appear in the player before the stream begins. To prevent distortion or cropping, make sure the image has the same aspect ratio as the source video. Poster images must be GIF, JPEG, or PNG format and no larger than 2.5 MB.
  • Player Logo – (Optional) A logo or other partially transparent image that appears in the player before and during playback. Upload a logo or other image file that's GIF, JPEG, or PNG format and no larger than 2.5 MB. Then, specify the corner of the player to which you want to anchor the logo.
Note: With the original HTML5 player, the player logo doesn't appear in the Flash fallback player.

Hosted Page Settings tab

  • Wowza Video Hosted Page – A webpage hosted by Wowza Video that includes the video player. Select Yes to have Wowza host a webpage for your live stream. Select No to manage video playback yourself.

If you don't use a hosted page, you can embed the player on your own webpage or use your own player. After you create the live stream, Wowza Video provides the embed code and playback URLs you need for those playback methods.

Note: You can't add a hosted page after the live stream is created.
  • Hosted Page Title – A short, descriptive title that appears above the player. HTML, JavaScript, and other tags aren't allowed. If you leave the Hosted Page Title field empty, Wowza Video uses the Live Stream Name as the page title.
  • Hosted Page Logo – (Optional) A graphical logo of your choosing that appears above the player. The logo file must be GIF, JPEG, or PNG format and no larger than 2.5 MB. Wowza Video resizes the image to fit the space on the page.
  • Hosted Page Description – (Optional) A longer text description of the stream or event that appears below the player. HTML, JavaScript, and other tags aren't allowed.
  • Sharing Icons – (Optional) Buttons that let viewers quickly share the link to the video on Facebook, Google+, Twitter, and by email. Sharing icons appear below the player and below the Hosted Page Description, if there is one.
