Detailed Description

This section explains users interact and how to configure user settings.

Users can be seen on the server after a successful call to TT_DoLogin. Once logged in a user can send user to user text-messages using TT_DoTextMessage as well as receive broadcast messages. A user cannot send audio and video data to other users until they have joined the same channel.

Sections:

User Types

A user can either be a default user USERTYPE_DEFAULT or an administrator USERTYPE_ADMIN. A default user has limited rights on the server (see uUserRights of UserAccount) whereas an administrator can change server properties, create, delete and remove channels as well as move, kick and ban users. Checkout User Administration on how to set up user rights.

User Interaction

Once a user has joined a channel it is possible to transmit voice and video data to other users. If a user starts talking in the channel the event CLIENTEVENT_USER_STATECHANGE is posted to the user application and if a video frame is received the event CLIENTEVENT_USER_VIDEOCAPTURE is sent to the user application.

User Audio Settings

While in the same channel the user application can change different settings on a user. If e.g. a user's volume is too low the user application can call TT_SetUserVolume to increase the volume.

If on the other hand the user application wants to mute a user TT_SetUserMute can be used for this. Note that muting a user doesn't mean that the client instance will stop receiving audio from that user, it simply means it will not be played. To stop receiving audio from a user the local client instance must ask the server to unsubscribe voice data from the user. This is explained in the next section.

User Subscriptions

When logging on to a server the local client instance will by default subscribe to user messages, channel messages, broadcast messages, audio data and video data from all users. If, however, a client wants to stop receiving e.g. audio from a user, he can call TT_DoUnsubscribe along with the user ID and the SUBSCRIBE_VOICE-flag to tell the server that he no longer wants to receive audio from that user. The server will then respond with the event CLIENTEVENT_CMD_USER_UPDATE and the uLocalSubscriptions member of User will have the SUBSCRIBE_VOICE-flag removed. At the remote user the uPeerSubscriptions member will be changed. Subscribe/unsubscribe can also be done for user, channel and broadcast messages and video data. The function TT_DoSubscribe can be used to revert unsubscriptions.

Spying on Users

Previously it has been said that users can only receive audio and video from users when they are in the same channel, but actually an administrator user can call TT_DoSubscribe with the flags prefixed SUBSCRIBE_INTERCEPT_* to spy on users outside his own channel. In other words it's possible hear and see video data outside ones channel. Also all user and channel messages sent by a user can also be intercepted in this way.

Having the ability to intercept all data sent from users in any channel means that it's possible to log everything that is happening on the server. Both audio and video transfers as well as text messaging. Checkout TT_SetUserMediaStorageDir() on how to store voice data to audio files.

Typedef Documentation

◆ UserType

typedef enum UserType UserType

See also: User; UserAccount

◆ UserTypes

typedef UINT32 UserTypes

A bitmask based on UserType describing the user type.

See also: UserType

Definition at line 1909 of file TeamTalk.h.

◆ Subscription

typedef enum Subscription Subscription

A user by default accepts audio, video and text messages from all users. Using subscribtions can, however, change what the local client instance is willing to accept from other users.

By calling TT_DoSubscribe and TT_DoUnsubscribe the local client instance can tell the server (and thereby remote users) what he is willing to accept from other users.

To check what a user subscribes to check out the User struct's uLocalSubscriptions. The subscriptions with the prefix SUBSCRIBE_INTERCEPT_* options can be used to spy on users and receive data from them even if one is not participating in the same channel as they are.
