Methods

addOnDirectionChange

▸ addOnDirectionChange(value: IAction0): void

Adds a handler that is raised when the stream direction changes.
Stream direction indicates the direction of media flow. For example:

  • A stream in an SFU upstream connection has a direction of SendOnly.
  • A stream in an SFU downstream connection has a direction of ReceiveOnly.
  • A stream in an MCU connection has a direction of SendReceive if it is attached to both local and remote media. If it is only attached to local media, it has a direction of SendOnly. If it is only attached to remote media, it has a direction of ReceiveOnly.
The direction of a stream can change over its lifecycle. For example:
  • An update to an SFU upstream connection might instruct the stream to stop sending audio or video frames. In this case, the direction of the stream changes to Inactive.
  • An update to an SFU downstream connection might cause it to stop receiving audio or video frames. In this case, the direction of the stream changes to Inactive.
  • An update to an MCU upstream connection might instruct the stream to stop sending audio or video frames. In this case, the following occurs:

    • If the direction of the stream was SendOnly, then the direction changes to Inactive.
    • If the direction of the stream was ReceiveOnly, then the direction changes to SendReceive.
  • An update to an MCU upstream connection might instruct it to stop receiving audio or video frames. In this case, the following occurs:
    • If the direction of the stream was ReceiveOnly, then the direction changes to Inactive.
    • If the direction of the stream was SendReceive, then the direction changes to SendOnly.
An event handler bound to the change in direction can be used to update the UI accordingly so the user is aware of the change in the state of the application.

removeOnDirectionChange

▸ removeOnDirectionChange(value: IAction0): void

Removes a handler that is raised when the stream direction changes.
Stream direction indicates the direction of media flow. For example:

  • A stream in an SFU upstream connection has a direction of SendOnly.
  • A stream in an SFU downstream connection has a direction of ReceiveOnly.
  • A stream in an MCU connection has a direction of SendReceive if it is attached to both local and remote media. If it is only attached to local media, it has a direction of SendOnly. If it is only attached to remote media, it has a direction of ReceiveOnly.
The direction of a stream can change over its lifecycle. For example:
  • An update to an SFU upstream connection might instruct the stream to stop sending audio or video frames. In this case, the direction of the stream changes to Inactive.
  • An update to an SFU downstream connection might cause it to stop receiving audio or video frames. In this case, the direction of the stream changes to Inactive.
  • An update to an MCU upstream connection might instruct the stream to stop sending audio or video frames. In this case, the following occurs:

    • If the direction of the stream was SendOnly, then the direction changes to Inactive.
    • If the direction of the stream was ReceiveOnly, then the direction changes to SendReceive.
  • An update to an MCU upstream connection might instruct it to stop receiving audio or video frames. In this case, the following occurs:
    • If the direction of the stream was ReceiveOnly, then the direction changes to Inactive.
    • If the direction of the stream was SendReceive, then the direction changes to SendOnly.
An event handler bound to the change in direction can be used to update the UI accordingly so the user is aware of the change in the state of the application.
