Adding a Source - NDI

zen master can receive a source directly from an ndi input because ndi streams are provided to the broadcaster as raw video frames, you need to encode the stream by selecting a transcoding profile that encodes both the video and audio (i e doesn't pass through either the video or audio) ndi sources are only supported on v14+ broadcasters pid mapping and scte 35 logging are not available with ndi because this data does not appear in ndi streams ndi sources can be resized but not padded with black bars enabling the “keep aspect ratio” checkbox in the transcoding profile will cause the transcoder to fail the following procedure describes how to add an ndi source in zen master in addition, an explanation of each of the configuration parameters is given in the table below to add an ndi source in the main navigation, click sources click + add the create new source selection window is displayed create source options click on ndi the create new ndi source window opens new ndi source in the info section, in the name field, enter a unique name to identify this source in the system in the tags field, select one or more of the predefined tags from the drop down list tags are used for access control by selecting a tag, you are relating this source to that tag tags are associated with certain roles (through the users & roles screen), and roles, in turn, are associated with users and user groups if you would like to create a new tag, see docid\ ypm9tw81ap6nq8stkv4rd in the events configuration profile field, select from the dropdown list the profile that you would like to apply to this source by default, the default profile is applied events profiles consist of a series of rules that determine precisely how various types of events are logged and what results they trigger the source's location is used to represent it in the proper position in the map display (see docid\ sfzm6jvorvuigo7x0dnue ) by default, the location is determined automatically based on the source's ip if you would like to manually set the location of the source (optional), use the following procedure click on the edit icon next to the location field a search box is shown below the location field enter identifying info for the location (e g street address, zip code, coordinates) search results are displayed below the search box as you type click on the desired location the selected location populates the location field in the configuration section, in the ingest cluster field, select from the drop down list one of the available ingest clusters as the destination for the source in the target broadcaster/s field, select your broadcaster preference either select a specific broadcaster to be used or specify your preference for using primary vs backup broadcasters, options are prefer primary broadcasters, primary broadcasters only, backup broadcasters only or prefer backup broadcasters for managed clusters, it is not recommended to select a specific broadcaster, as the broadcaster’s availability may not remain stable in the ndi stream field, select from the drop down list the desired ndi stream on the local network where the broadcaster is hosted in the profile field, select one of the pre configured profiles to apply to this source if you would like to create a new transcoding profile, see docid 3l1dnio6v 15jzcfdhrkn you must select a transcoding profile that either encodes both the video and audio or transcodes one and removes the other a profile that passes through either the video or audio cannot be used if you would like to assign the transcoding process to a multi gpu broadcaster, select the assign to gpu checkbox, and then select from the drop down list the desired gpu instance options are 0(default), 1, 2 and 3 this feature is useful if you are running several heavy transcoding activities, as it enables you to distribute the load among several different gpus in the pad to cbr field, enter the amount of cbr padding to be added (in kbps) in the audio reference level field, enter the audio reference level (0 20) if you would like to generate email notifications whenever a pid change is detected, select the alert on pid changes checkbox in the public output field, if you would like to allow access to the stream directly through a supported player, select the allow checkbox if you selected the allow checkbox, then enter a password in the password field to authenticate access to the stream under content analysis select one of the following options full select this option if you would like to enable full content analysis (cqa), including analysis of the stream's audio and video content, including audio levels, audio silence detection, frozen video detection, and more tr101 only select this option to perform tr101 analysis only (without video and audio content analysis) the analysis can be used to check the integrity of the ts and the most important elements of the stream the analysis includes priority 1 and 2 to learn more about tr101 analysis see https //www etsi org/deliver/etsi tr/101200 101299/101290/01 03 01 60/tr 101290v010301p pdf none no content analysis is enabled it is generally recommended to enable full content analysis unless it is causing technical problems if content analysis is disabled, the system won't detect errors in the video and audio content of the stream and won't generate warnings for such events if you would like to monitor cea 608 closed captions, select monitor cea 608 checkbox monitoring cea 608 closed captions requires using a version 14 4 or newer broadcaster if you would like to monitor cea 708 closed captions, select monitor cea 708 checkbox monitoring cea 708 closed captions requires using a version 14 4 or newer broadcaster if you would like to disable auto pull, select the disable auto pull checkbox disabling auto pull will lock channels using this source to the source's ingest cluster and targets to the source's current active broadcaster this setting only applies to pass through channels if auto pull is enabled , in the auto pull latency \[ms] field, specify the maximum latency for auto pull actions (default 1000 ms) in the webrtc playback section, select the desired playback method webrtc enables you to monitor the stream via web browsers and mobile applications with real time communication (rtc) webrtc needs to be activated independently for each source in zen master (by default it is disabled) select one of the following options disabled users will not be able to view this source using webrtc (default) pass through passes the stream through to webrtc without transcoding this option can only be used if the input stream is already in a webrtc compliant format (video h 264 codec with baseline or main profile and no b frames, audio opus codec) auto zen master automatically transcodes the stream using the optimal profile for each specific user in this option zixi broadcaster will decode the video, transforming it into raw frames, which will be passed to the webrtc library, where it will be re encoded for each individual user best quality however, if monitored by multiple users this can consume extensive resources 1080p/720p/480p/360p zen master transcodes the stream to a webrtc compliant profile with the specified resolution the transcoding is done by zixi broadcaster's transcoder this method requires a zixi broadcaster with x264 or nvidia for transcoding this method allows many users to monitor the stream without encoding separately for each individual user, which saves cpu capacity since there is only one stream version, it is recommended to encode to a low resolution and low bitrate so that the stream will be viewable by all users monitoring the stream additional scte 35 options are available when you expand the scte 35 manipulation section scte 35 manipulation here you can enable scte 35 insertion specify the length of a search window for a null packet for scte 35 intertion set the scte 35 pid remove any existing scte 35 messages from the stream see the parameters table below for an explanation of these options in the initial state section, select the disabled checkbox if you would like to disable this source upon initial configuration select the muted checkbox if you would like to disable error/recovery notifications for this source upon initial configuration under audio sources configuration , assign one or more audio channels to one or more audio pids following the assignment of the audio channels to the audio pids, you will be able to encode them separately and include them in the mpeg ts for example let's assume the ndi source has 8 audio channels (0 7) you can create 4 audio pids with the following configurations pid 1002 0,1 pid 1003 2,3 pid 1004 4,5,6,7 pid 1005 2,3 to assign channel(s) to a pid under channel , assign a channel to the pid by selecting a channel for from the drop down menu repeat the process to add additional channels to the pid to configure additional pids, click add+ and select the corresponding channel(s) if you would like to adjust the advanced settings, click advanced the advanced settings fields are displayed
