The Enable Multi-Input Encode license lets each Prism encoder pipeline encode its own video input, so one unit can encode and stream two different cameras at the same time, for example SDI 1 on one pipeline and HDMI on another. This license covers purchasing/installing the license, and the multi-input encoding feature.
The Enable Multi-Input Encode license is available for Prism Flex, Prism Mobile, and Prism 877 cards running firmware 2.26 or later.
By default, Prism encodes video from a single physical video input or network ingest. The inputs view on the pipelines page can be used to select which of the inputs are active. Video input can also be changed from within an individual pipeline configuration page, but it will apply to all encoder pipelines.
After installing the license, Inputs can be selected for each encoder pipeline, from within its configuration page. The Inputs section of the Pipelines overview does not operate as an input selector after the license is installed. In the image below, Encoder 1 encodes SDI 1 and Encoder 2 encodes HDMI, each with its own streams.
Installing the license
Each license is issued for one device and only works on the unit with that serial number. You will need to provide your serial number when purchasing the license.
To find the serial number:
- Select Maintenance in the sidebar. The serial number is in the System Info card.
- Click the copy icon next to Serial number to copy it (see image below).
NOTE: Encoder pipelines restart when the license activates, so streams and recordings stop for a few seconds. Install the license when Prism is not live.
- Purchase the Enable Multi-Input Encode license. If you don't have one, contact [email protected] to purchase one.
- Enter your Prism's IP address in a web browser to open the web UI.
- Select System Settings in the sidebar, then select Licenses at the bottom of the page. The Licenses card lists the licenses installed on the device (see image below).
- Click Enter license key, paste your license key, then click Confirm (see image below).
- The dialog shows License activated with the license name, its status, and its activation and expiration dates. Click Done. Enable Multi-Input Encode appears in the Licenses card with the status Active (see images below).
Selecting an Encoder Input
- Select Pipelines in the sidebar, then select the encoder pipeline (for example Encoder 1).
- Click INPUT in the pipeline header, then select the input to encode (see image below).
- Repeat for each encoder pipeline. To add a pipeline, click Add Pipeline on the Pipelines page and choose its input in the New pipeline dialog.
- To check the routing, select Signal Flow in the sidebar. Each input is connected to the pipeline that encodes it (see image below).
On Prism Mobile and Prism Flex, the SDI 2 port can also be used as an input: set SDI 2 to Input in the Outputs section of the Pipelines page. While set to Input, SDI 2 does not output video.
