Live Media Feed APIs
LiveMediaFeed Entity
The LiveMediaFeed entity has the following properties:
Id
int:(read only) The identifier and primary key of the LiveMediaFeed instance.Name
string: The user-defined name of the LiveMediaFeed instance. This alternate key must be unique in the scope of the BrightSign Network account.TTL
TimeSpan: The amount of time that the Live Media Feed can be cached on the client (i.e. player) before it is refreshed from the source. Note that the caching behavior of the media files themselves is determined by settings on the player.PhysicalPath
string:(read only) The external URL of the associated MRSS file in the persistent storage.FileSize
long:(read only) The size of the associated MRSS file (in bytes).FileHash
string:(read only) A SHA1 hash of the associated MRSS file contents.CreationDate
DateTime:(read only) A UTC timestamp indicating when the Live Media Feed was created in the BrightSign Network.Contents
LiveMediaFeedContent[]: An array of LiveMediaFeedContent entity-relations that reference content instances contained within the Live Media Feed. This list is set to Null when not initialized by the server.
LiveMediaFeedContent Entity-Relation
The LiveMediaFeedContent entity-relation represents associations between a Content instance and a LiveMediaFeed instance. It has the following properties:
ContentId
int: The identifier and primary key of the associated Content instance. This value can be set by either the client or the server.FileName
string: The virtual name of the file represented by the current Content instance.Title
string: The key (i.e. MRSS item title) of the associated media item in the related Live Media Feed.Description
string: The value (i.e. MRSS item description) of the associated media item in the related Live Media Feed.DisplayDuration
TimeSpan: The amount of time the player will display the associated image file. This property does not apply to audio or video files.ValidityStartDate
DateTime: A value that determines the validity start date for the associated content item (i.e. the point at which the content item will be start being displayed in the Live Media Feed). A Null value determines that the content item is valid from the moment it is added to the Live Media Feed; this is the standard case for most content items.ValidityEndDate
DateTime: A value that determines the validity end date for the associated content item (i.e. the point at which the content item will no longer be displayed in the Live Media Feed). A Null value determines that the content item will be valid until it is removed from the Live Media Feed manually by the user; this is the standard case for most content items.CustomFields
Dictionary<string, string>: A dictionary of key and value pairs. Each pair represents a custom field associated with the media item in the MRSS file of the related Live Media Feed.
Live Media Feed Management Web Methods
PagedList<LiveMediaFeed> GetLiveMediaFeeds(string marker, int pageSize)

Parameters
liveMediaFeedIds
int[]: An array ofId
int values for the LiveMediaFeed instances being requested. The number of returned items is limited to 100 by the server. Attempting to request more than the maximum allowed number of objects will cause an error, while passing an empty array will lead to an immediate empty response without an error.
PagedList<LiveMediaFeed> FindLiveMediaFeeds(string namePattern, string marker, int pageSize)
