TRTCKaraoke APIs
TRTCKaraokeRoom includes the following features, which are based on Tencent Real-Time Communication (TRTC) and Tencent Cloud Chat.A user can create a karaoke room and become a speaker or enter a karaoke room as a listener.
The room owner can manage song requests as well as remove a speaker from a seat.
The room owner can also block a seat. A listener cannot request to take a blocked seat to become a speaker.
A listener can become a speaker to request songs and sing. A speaker can also become a listener.
All users can send gifts as well as custom chat messages. Custom messages can be used to send on-screen comments and give likes.
Note
TRTCKaraokeRoom is an open-source class that depends on two closed-source Tencent Cloud SDKs. For the specific implementation process, see Karaoke (Android).The TRTC SDK is used as a low-latency audio chat component.
The
AVChatRoom feature of the Chat SDK is used to implement chat rooms. The attribute APIs of Chat are used to store room information such as the seat list, and invitation signaling is used to send requests to speak or invite others to speak.
