This This screen enables the Broadcaster to receive an HLS stream. The HLS stream is not protected by the Zixi protocol. The There are two options for pulling the stream:
- Single source (adaptive bitrate) - the stream can be an adaptive bitrate stream. In this case, Zixi Broadcaster will pull the main playlist to adapt between
...
- bit-rates according to network conditions.
- Multiple sources - it is possible to pull multiple input streams with static individual
...
- bit-rates. In this case, Zixi Broadcaster will automatically create a separate input for each bitrate.
To Add an HLS stream:
- In the Zixi Broadcaster Navigation menu, click the Inputs tab.
- In the Menu bar, click New Input. The Add a new input stream window is displayed.
Enter the unique Stream I.D.
Info Note this must be identical (case sensitive) to the stream name configured in the Zixi Feeder.
- Enter the maximum concurrent connections to this stream from the Max. Outputs drop-down list. Default: Unlimited.
- Select the Show in Matrix check box to display this stream in the Matrix (see Using the Matrix). Default: Selected.
- Select HLS for the input stream.
- Specify the Stream Parameters (see Input Streams Parameters Table b below).
- If you want to Enable time shift, select this checkbox (see Input Streams Parameters Table).
- If you want to Transmit as multicast, select this checkbox (see Input Streams Stream Parameters Table).
- If you want to configure the Recording Parameters,specify them in the respective fields (see Input Streams Stream Parameters Table).
- If you want to Enable encryption select this checkbox (see Input Streams Stream Parameters Table).
- Click OK.
The “Input added” message appears on the top of the screen. The UDP Stream HLS stream from the Zixi Feeder is added to the Zixi Broadcaster and now appears in the list of streams available in the Zixi Broadcaster inputs UI. If the "multiple sources" option was select, Zixi Broadcaster will automatically create a separate input for each bitrate.
Input Stream Parameters Table
| Parameter | Description | ||
|---|---|---|---|
| Stream | IDparameters | ||
| Master Playlist URL | Specify the unique identifier for this stream. | ||
| Max Outputs | Specify the maximum number of allowed outputs. Default: Unlimited. | ||
| Show in Matrix | Show input in matrix. | Stream parameters | |
| URL | Specifies the URL of the HLS stream. | ||
| Enable time shift | Enables a delayed transmission of this inputURL of the HLS stream's master playlist. | ||
| Download Type | Specify whether the variants will be pulled from a single source (adaptive bitrate) or multiple sources (pull all bitrates). | ||
| Smoothing Latency | The Smoothing feature uses a buffer to time packets according to the stream's clock. This is useful when there are bursts in the rate in which the stream arrives. The smoothing features creates a queue in the buffer, allowing smoother entry into the Broadcaster. The Smoothing parameter defines the size of the buffer in Milliseconds. A larger buffer enables smoother entry, however, it may influence the latency rate. | ||
| Inject SCTE35 on CUE Marks | Select this checkbox to inject SCTE markers into the adaptive stream manifest. SCTE-35 markers found in the source input will be used to segment the stream and the #EXT-X-CUE-IN/#EXT-X-CUE-OUT tags will be added to the manifest. | ||
| Enable time shift | Select this checkbox to record the stream content and broadcast it after a specified delay. To deploy an input stream that uses the current stream's time shift, you need to configure a "Delayed" input stream. (See Adding Delayed Streams). | ||
| Maximum delay [hh:mm:ss] (for Time Shift enabled) | Specify the maximum time delay of this input. | ||
| Transmit as multicast | Enables Select this checkbox to enable the transmission of this stream’s outputs as multicast. A Zxi Receiver Zixi receiver that will pull the stream will receive it in multicast (unless . By default Zixi Broadcaster is configured to allow transparent fallback to unicast if it is out of the LAN in which case it will receive as unicast). You can also force Multicast only outputs. Requires enabling Multicast Pull in the Settings. | ||
| Multicast-Only (for Multicast enabled) | If desired, specify multicast only outputs. | ||
| Enable Encryption | Select this checkbox to encrypt the Input stream. For more information, see Encrypting an Input Stream in Zixi Broadcaster. | ||
Encryption type (for Encryption enabled) | Specify the type of Encryption (AES 128/192/256). Selection of Automatic will generate an AES 256 bit encryption and exchange it securely between the applications automatically. (for more information, see Encrypting an Input Stream in Zixi Broadcaster) | Encryption key | Click Generate and the encryption key for the input stream will appear in the adjacent text box. Send it |
Encryption key (for Encryption enabled) | Click Generate to generate an encryption key. The generated encryption key must be sent to the end-user to decipher the received encoded stream. | ||
Recording parameters | Select this checkbox to customize the recording parameters. | ||
Destination Type | Select the radio button for the desired storage type and then fill in the relevant parameters. · Record to disk – the recording is saved on the local disk. · Record to S3 – the file is saved to your AWS S3 Bucket. | ||
Record to Disk Parameters | |||
File Name Template | Specify the file name pattern that Zixi will use to generate when saving the recorded content. A separate file will be generated for each recording up to the time specified in the Max recorded file duration parameter (see above). After this duration a new file will be generated. The file name pattern can include any string and up to five variables listed below. Only the %T=HH.MM.SS creation time is mandatory. You can change the order of these variables and add text as long as you maintain the legitimate structure of the file in Linux and Windows: · %S=stream id - optional. · %Y=year - optional · %M=month - optional · %D=day - optional · %T=HH.MM.SS creation time - mandatory For example, the following pattern %Y_recording%T.ts will generate the following file name 2017_recording15:32:35.ts. | ||
Max recorded file duration [hours] | Specify the maximum time allotted for recording a video stream. Default: 2 hours | ||
Keep recorded files for [hours] | Specify the maximum time for storing the recording. Default: 0 hours | ||
Custom Path | Optionally specify a storage location for the recorded files that is relative to the root folder. This location bypasses the location specified as the root folder in the Settings > General screen. | ||
Record to S3 Parameters | |||
File Name Template | Specify the file name pattern that Zixi will use to generate when saving the recorded content. A separate file will be generated for each recording up to the time specified in the Max recorded file duration parameter (see above). After this duration a new file will be generated.

Max recorded file duration [hours] | Specify the maximum time allotted for recording a video stream. Default: 2 hours | ||
URL | Specify the URL of the S3 bucket. | ||

Access Key | The access key that is used for accessing the S3 bucket. | ||
Secret Key | The secret key that is used for accessing the S3 bucket. | ||
