Interface VideoStreamIndex

Determines if the stream ID's are from the same group (client)

Returns the set of all streams as VideoStreamIdSet

Returns an array of video sources who are sending video excluding self

Returns attendee id for a group id

Returns attendee id for a stream id

Returns attendee id for a track id

Returns external user id for a track id

Returns a group id for an SSRC

Returns group id for a stream id

Returns the set of the highest quality videos for subscription

Saves [[SdkBitrateFrame]] in VideoStreamIndex

Saves [[SdkIndexFrame]] in VideoStreamIndex

Saves [[SdkSubscribeAckFrame]] in VideoStreamIndex

Updates cached local stream description array via uplink decisions, an array of [[RTCRtpEncodingParameters]]

Returns the cloned array of VideoStreamDescription corresponding to local streams

Returns the number of video participants

Returns the number of participants who are publishing videos excluding self

Override mappings using stream ID (i.e. for streamIdForTrack, and streamIdForSSRC) locally (i.e. without the need for a subscribe ACK message)

Returns the cloned array of VideoStreamDescription corresponding to remote streams

Returns a stream id for an SSRC Id

Returns a stream id for a track id

Return a selection set of streams for subscription based on self attendee id, size information of tiles, bandwidth limitation

Returns the set of streams which are paused at source.

This function caches the currently ingested index frame (and may be eventually renamed). It can use the stored index as a backup for map functions like groupIdForStreamId and can be used for:

• Maintaining consistent information during a subscribe even if an index is received concurrently
• Maintaining information about previous senders simulcast streams to enable stream switching, e.g. if a sender is transmitting low/hi and switches to just low, receivers need the previous index to be able to know what group ID the high stream corresponds to.
