Detailed Description

Users can be seen on the server after a successful call to TeamTalk4.DoLogin(). Once logged in a user can send user to user text-messages using TeamTalk4.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.

User Types

A user can either be a default user UserType USERTYPE_DEFAULT or an administrator UserType USERTYPE_ADMIN. A default user has limited rights on the server whereas an administrator can change server properties, create, delete and remove channels as well as move, kick and ban users.

User Interaction

Once a user has joined a channel it is possible to transmit audio and video data to other users. If a user starts talking in the channel the event TeamTalk4.OnUserTalking() is posted to the user application and if a video frame is received the event TeamTalk4.OnUserVideoFrame() 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 TeamTalk4.SetUserVolume() to increase the volume. If it's still not loud enough TeamTalk4.SetUserGainLevel() can be called to use software to amplify the volume level.

If on the other hand the user application wants to mute a user TeamTalk4.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 audio 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 TeamTalk4.DoUnsubscribe() along with the user ID and the Subscription SUBSCRIBE_AUDIO-flag to tell the server that he no longer wants to receive audio from that user. The server will then respond with the event TeamTalk4.OnCmdUserUpdate() and the uLocalSubscriptions member of BearWare.User will have the Subscription SUBSCRIBE_AUDIO-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 TeamTalk4.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 TeamTalk4.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 TeamTalk4.SetUserAudioFolder() on how to store voice data to audio files.

Enumeration Type Documentation

enum BearWare.UserType : uint

User
Enumerator
USERTYPE_NONE 

Used internally to denote an unauthenticated user.

USERTYPE_DEFAULT 

A default user who can join channels.

USERTYPE_ADMIN

enum BearWare.Subscription : uint

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 TeamTalk4.DoSubscribe() and TeamTalk4.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 BearWare.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.
