ZEC Adding HTTP Push Outputs

The HTTP Push output stream can be encapsulated in HLS or DASH.  The source of the output stream is a predefined adaptive group that has been configured in the ZEC Adaptive Groups screen. The configuration of the stream includes the option to delete outdated stream fragments on the server. SCTE-35 markers in the source input will be preserved and used to segment the stream for both HLS and DASH encapsulation. Output streams can be pushed to one ZECs or ZEC. 

The path to the destination can be formed in one of the following ways:

  • Full path – in this option the path would be constructed as follows: <base url>/<path>/<file>?<aditional params may be also with path and file>
  • Path in parameters - in this option the path would be constructed as follows: <base url>?<aditional params may be also with path and file>
  • Flat path - in this option the path would be constructed as follows: <base url>/<path>_<file>?<aditional params may be also with path and file>. Any "/" in path should be replaced with "_"

Low Latency HLS - ZEC supports low latency HLS delivery using chunked transfer encoding, which starts sending an HTTP response as chunks of data when they are ready before the complete response is available. Chunked transfer encoding can be used with transport stream (TS) segments and with fragmented MP4 (fMP4). For low latency HLS and DASH, ZEC must be used as an origin server. To enable low latency HLS and DASH, select Enable HLS Fast playback on Settings > Live Protocols screen.

To create an HTTP Push Output:

  1. In the ZEC Outputs page, click . The New Output window is displayed.



  2. Select the HTTP Push option (radio button)
  3. Type in the unique identifier for this output stream in the Output Name.
  4. Select an Input Adaptive Group to be made available on this output from the adjacent drop-down list. To create an Adaptive Group, see ZEC Adaptive Groups.
  5. Select the Show in Matrix check box to display this stream in the Matrix (see ZEC Using the Matrix). Default: not selected.
  6.  Enter the Output Parameters (see Output Stream Parameters Table). 
  7. If your destination server requires authorization credentials to connect, select the Authorization checkbox
  8. Click OK
    The new HTTP Push Output with its settings is created and now appears on the screen.

Output Stream Parameters Table

ParameterDescription
Output Parameters

Encapsulation Options

  • HLS Encapsulation - the output stream, which includes all the streams in the selected Adaptive group, will be encapsulated in HTTP Live Streaming format.
  • Dash Encapsulation - the output stream, which includes all the streams in the selected Adaptive group, will be encapsulated in MPEG DASH format.

Target URL

Depending on the selection in the Segment Path field below, this field should include the following:

  • Full path – <base url>/<path>/<file>
  • Path in parameters - in this option the path would be constructed as follows: <base url>
  • Flat path - in this option the path would be constructed as follows: <base url>/<path>_<file>
Additional URL Parameters

Depending on the selection in the Segment Path field below, this field should include the following:

  • Full path – ?<additional params may be also with path and file>
  • Path in parameters -?<additional params may be also with path and file>
  • Flat path - ?<additional params may be also with path and file>. Any "/" in path should be replaced with "_"

URL parameters support macros as follows:

  • %PATH% - file path as it appears in the playlist
  • %FILE% - file name

Delete outdated stream fragments on server

Select this checkbox to delete any outdated stream fragments from the server.

Upload DVR playlistSelect this checkbox if you are streaming a recorded/VOD stream and you want to upload a DVR playlist in addition to the live playlist.
Segment Path

Select one of the following path segmentation types:

  • Full path – in this option the path would be constructed as follows: <base url>/<path>/<file>?<additional params may be also with path and file>
  • Path in parameters - in this option the path would be constructed as follows: <base url>?<additional params may be also with path and file>
  • Flat path - in this option the path would be constructed as follows: <base url>/<path>_<file>?<additional params may be also with path and file>. Any "/" in path should be replaced with "_"
Ignore TLS certificate errors
Select this option when streaming to a trusted server that does not have a valid certificate. When this option is selected, ZEC will ignore the TLS certificate errors and transmit the stream to its destination. 
AuthorizationSelect this checkbox if your destination server requires authorization credentials to connect.
Method

Select one of the following authorization methods:

  • Basic authorization
  • Digest authorization
  • OAuth2 authorization
UsernameType the username
PasswordType the password
