Kaltura recording and webcasting setup

Applies to: Pearl-2, Pearl Mini, Pearl Nexus, Pearl Nano.

Your Pearl device appears as an available resource as soon as the device is registered with Kaltura. Connect multiple audio and video sources directly to the Pearl device and assign them to separate channels. Each channel you configure on the Pearl device is treated as a separate video source.

About Kaltura recording and webcasting

Pearl devices support scheduled events, recurring events, and unscheduled ad hoc recordings and webcasts. After the Pearl device is registered, Kaltura users can simply assign the Pearl device as a resource when setting up an event using MediaSpace. Scheduled events start and end automatically. No manual intervention is required. After the event ends, the recording automatically uploads. Back up recordings for each channel are also saved locally on the Pearl device. A large capacity (256 GB or more recommended) storage is required to record CMS events. Do not remove any storage while files are uploading. If the network connection or the CMS goes down during an event, the Pearl device continues to record locally and uploads the recording when network connectivity resumes. Depending on how busy the Kaltura CMS system is when the files upload, it may take some time for the files to appear in Kaltura's media lists. You can start and stop events earlier than the scheduled time using the Admin panel or the device screen. With firmware 4.24.6 or newer, you can also pause and resume the recording during a Kaltura event. The Pearl device removes the paused section of the event before uploading. Starting or stopping a scheduled VOD event before the scheduled start or stop time does not change the event in to an ad hoc event. Pearl administrators can:

• Create ad hoc events.
• Set ad hoc event parameters.
• View the Events page to see all upcoming scheduled sessions and completed sessions.
• Change how often Pearl device polls Kaltura for an updated list of Events.
• Download local recordings for each channel.
• Start and stop scheduled events before the scheduled time.
• Extend, pause, and resume scheduled events. For details, see "Extend, pause, and resume CMS recordings and webcasts."
• Change the extend event button time allotment in 5, 10, and 15 minute intervals. General information
• The Pearl device must be registered with Kaltura to record and stream Kaltura events.
• Scheduled events have priority over ad hoc events. If an ad hoc event is still in progress when it's time to start a scheduled event, the ad hoc event is stopped and the scheduled event starts.
• Scheduled events automatically start recording locally on the Pearl device even If the network is down or Kaltura is unavailable. After the session ends, the locally recorded files upload automatically to your Kaltura media list when the network link to Kaltura is re-established.
• After the event ends, it may take a while for content to show up in Kaltura's media lists, depending on how busy the Kaltura CMS system is at that time.
• The recorded event must be a minimum of 2 minutes long for Kaltura to process the video.
• The Kaltura Editor does not open recorded events that are less than a minute long.
• If the time and zone settings of the Pearl device are out of synchronization with Kaltura's scheduling server, an error appears on the Events page and you're prompted to reconfigure the time settings on the Pearl device.
• Do not use Single Touch recording control, AFU or configure recording file size, type and other channel recording settings when CMS is enabled on Pearl device.
• If you modify a particular recurring lecture capture plus live webcasting event (e.g. a VOD + Live Stream event in a recurring series), Kaltura excludes that event from the recurring series and the webcast doesn't stream. That's because the RMTP URLs for the modified event looses it's mandatory tokens. However, the recurring Kaltura event does record as scheduled and other events in the series are not affected. Workarounds: To regenerate the RTMP tokens for a live event, go to MediaSpace, find the modified live event entry and uncheck the Live event checkbox - and save. Then re-check it and save the event again. Alternatively, you can go to the Kaltura Management Console (KMC), find the modified live event entry and then, in the Live stream tab, click Re-generate Stream Token.
• Do not schedule recordings that are longer than the capacity of Pearl device to store the recording on the local drive. Default Kaltura encoding settings are applied automatically to the channel when Kaltura is enabled, which override the existing encoding settings. If you manually change the encoding settings using the Admin panel after Kaltura is enabled, the settings revert back to the default Kaltura settings when a scheduled or ad hoc event starts. Pearl device information For events with multiple sources, the recording for each source is uploaded to Kaltura and appears as a single, multi-view entry in the Kaltura media list with each source (i.e. view) listed as a separate "child" sub-entry. The name of each file includes the name of the channel plus the date and time the file was recorded. For example: Channel 1_May23_10-12-05 We recommend that you configure the channel that is selected as the main entry as well as the other channels in a multi-view scheduled VOD event to include all audio sources. Audio is taken from the channel configured as the main entry in the Kaltura CMS. With Pearl device you can:
• Use multiple channels to get multiple views for a Kaltura event. Each channel is treated as a separate video source. Using the Admin panel, Pearl administrators can choose channels on Pearl device for multiple source recordings. For webcasting, you can select only one channel at a time.
• For example, if you have a main camera and a presentation laptop that you want to capture as a multiple source recording, you'd create two channels on Pearl device: one for the main camera and another one for the presentation laptop.
• Set the video source that is used as the default main entry. The channel selected as the main entry becomes the default view that people see when watching the VOD, as well as the main view (i.e. the large screen) for PiP.
• Set which Pearl device channels are used for scheduled and ad hoc recordings and webcasts.
• Set the channel used for scheduled and ad hoc webcasts.
• Display the Channel view on the Pearl device's touch screen or monitor channels using the Admin panel. You can also monitor channels directly on the Events screen using the touch screen.

Device differences

• Pearl Nano: Pearl Nano cannot display the Channel preview on the Events screen. You can still display the Channel view on Pearl Nano's front screen Channel view, or monitor the channel using the Admin panel.
• Pearl Nexus: Pearl Nexus has no screen. Create ad hoc events using the Admin panel or third-party control. Start, stop, and extend scheduled events using the Admin panel, Epiphan Edge, or third-party control.
