ZEC Adding RTMP Streams
This enables you to create a Push or Pull RTMP input stream.
To Add an RTMP Stream:
In the ZEC 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 ID.
Note this must be identical (case sensitive) to the stream name configured in the sending Zixi Broadcaster or MediaConnect.
Select 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 ZEC Using the Matrix). Default: Selected.
Select the Log this stream checkbox if you would like to generate event logs for this input.
Select the Analyze checkbox if you would like to enable stream analysis for the input.
Select RTMP for the input stream, and then choose Push or Pull - the fields will vary according to which type you choose.
Push RTMP:
Pull RTMP:
Specify the Stream Parameters (see the Input Stream Parameters TableInput Stream Parameter Table below).
If you want to Enable encryption, select this checkbox (see Input Stream Parameters Table). For more information, see ZEC Encrypting an Input Stream.
If you want to configure the Recording Parameters, specify them in the respective fields (see Input Stream Parameters Table)
Click OK.
The “Input added” message appears at the top of the screen. The stream is added to ZEC and now appears in the list of streams available in the ZEC inputs UI.
Input Stream Parameters Table
Parameter | Description |
|---|---|
Stream Parameters | The general stream settings. |
Type | Select the desired type for the RTMP stream:
|
URL (for Pull) | Type the Stream URL from which ZEC will access. Use the following URL format: rtmp://host:[port]/app/stream. You can define RTMPS clients with the proven security of a secure socket layer (SSL), by using the rtmps:// url |
Stream Name (for Pull) | Type the unique name for the stream that has been defined in the RTMP server. |
Username (for Pull) | Specify the user name to authenticate on the remote RTMP server |
Password (for Pull) | Specify the string that is used for authorization on the remote RTMP server. |
Bind to IP | Select from the drop-down list the local IP address to be used for this Input, OR select Any to enable any IP to be used. |
Ignore TLS certificate errors (for Pull) | Select this option when connecting to a trusted server that does not have a valid certificate. When this option is selected, ZEC will ignore the TLS certificate errors. |
Disconnect if inactive | Disconnects the connection if inactive. |
MPEG-TS Multiplexing Bitrate [kbps]: | If the stream's bitrate fluctuates, you can pad the stream with null packets to create a steady bitrate. Specify the padding level in kbps. |
Smoothing Latency [ms] | 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 at which the stream arrives. The smoothing feature creates a queue in the buffer, allowing smoother entry into ZEC. The Smoothing parameter defines the size of the buffer in Milliseconds. A larger buffer enables smoother entry; however, it may influence the latency rate. |
Enable encryption | Select this checkbox to encrypt the Input stream. The stream encryption prevents any further processing, such as analysis, transcoding, etc. The encryption works in the following way:
For more information, see ZEC Encrypting an Input Stream. |
Encryption type (for Encryption enabled) | Specify the type of Encryption (AES 128/192/256). |
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 Parameters | |
File Name Template | Specify the file name pattern that ZEC 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:
For example, the following pattern %Y_recording%T.ts will generate the following file name 2022_recording15:32:35.ts. |
Max recorded file duration [HH:MM] | Specify the maximum time allotted for recording a video stream. Default: 2 hours |
Keep recorded files for [HH:MM] | 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 ZEC 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:
For example, the following pattern %Y_recording%T.ts will generate the following file name 2022_recording15:32:35.ts. |
Max recorded file duration [HH:MM] | Specify the maximum time allotted for recording a video stream. Default: 2 hours |
URL | Specify the URL of the S3 bucket. |
Ignore TLS certificate errors | TLS certificate for S3 bucket might be detected as faulty if bucket name contains dot[s]. When this option is selected, ZEC will ignore the TLS certificate errors and transmit the stream to its destination. |
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. |
Advanced Mode
The fields discussed below are optional and available only in Advanced Mode.
To enter Advanced Mode add the URL parameter ?advanced=1 to the ZEC URL in your browser and press Enter/Return to reload the page:
Note the Advanced Mode settings are generally intended for advanced users and special cases. If you do not understand the settings, you should probably accept the default values.
General
- Latency Offset [ms] - Specify the additional buffering time in milliseconds. Increasing this value can improve stream stability in unstable network conditions, but will increase end-to-end delay. Default: 0 ms
- Inject Metadata - allows Zixi create a PID that carries information about what hops a feed has travelled through on the way to its destination, it includes things like CC errors and IAT at each hop. The information is useful for debugging issues with streams.
- Support SCTE-35 injection - Select this checkbox if you would like the stream to support SCTE-35 insertion.
- SCTE-35 PID - Enter a PID number for SCTE-35 injection. You can enter a value manually or use the Up/Down arrows that appear when clicking the field. (or leave as Auto to match existing SCTE-35 PID)
- Remove old SCTE-35 packets - If SCTE-35 injection is supported, select this checkbox to clear out existing packets.
- Timeout for CBR - Time in MS to wait for a NULL packet to inject SCTE-35 into.
Stream Parameters
- Max Bitrate [kbps] - Specify the maximum expected bitrate for memory allocation. Recommended: 2X the actual bitrate, which will prevent buffer overruns (especially with VBR streams). Default: 8000. Note – Overflows will typically occur when the Max Bitrate isn’t sufficient.
- Compression - Enables bandwidth optimization by replacing NULL packets with signaling information embedded in packet headers. This reduces the overall bitrate without affecting content integrity. Since not all receivers support this compression method, it is optional. The system can receive compressed streams, but will only transmit compressed data when this option is explicitly enabled.
- Fast Connect - Enables faster session establishment by reducing the time required to initiate the RIST connection. This is useful in environments where rapid recovery or quick stream startup is required. Support for this feature may vary depending on the receiving endpoint.
