Live Audio Room Kit(Flutter) Sharing Media

You can share local or network music and videos in the audio chat room through the media API or media player we provide.

If you want to call the media-related APIs, you can do so by using ZegoUIKitPrebuiltLiveAudioRoomController().media.

The media APIs we provide are as follows:

play({required String filePathOrURL, bool enableRepeat = false})

Play local or network media by setting filePathOrURL. If you want to play it repeatedly, you can set the enableRepeat parameter to true.
stop

Stop playing the current media file.
pause

Pause playing the current media file.
resume

Resume playing the current media file.
seekTo

Set the current playback progress.
setVolume

Set the volume.
volume

Get the volume.
muteLocal

mute local volume.
totalDuration

Get the total duration of the media file.
currentProgress

Get the current playback progress.
type

Get the current media type, which can be either pure audio or video. The media types are defined as follows:
Untitled
enum ZegoUIKitMediaType { PureAudio, Video, Unknown, }
1
Copied!
pickPureAudioFile

Select a local pure audio file.
pickVideoFile

Select a local video file.
pickFile

Select a local media file.

MediaInfo getMediaInfo

Get the media information of the current playing media, which is defined as follows:

Untitled

/// Media Infomration of media file.
///
/// Meida information such as video resolution of media file.
class ZegoUIKitMediaInfo {
  /// Video resolution width.
  int width;

  /// Video resolution height.
  int height;

  /// Video frame rate.
  int frameRate;
}

We describe the media APIs we provide through three scenarios below.

While chatting with others, having background music can make the conversation more interesting. Or if your App requires specific background music to create an atmosphere, you can use the following code to meet your needs.

Auto-play(Without UI)

If you want to automatically play background music when entering the voice chat room, you can setconfig.backgroundMedia.path：

Untitled

class LivePage extends StatelessWidget {
  const LivePage({Key? key, required this.roomID, this.isHost = false})
      : super(key: key);

  final String roomID;
  final bool isHost;

  @override
  Widget build(BuildContext context) {
    return SafeArea(
      child: ZegoUIKitPrebuiltLiveAudioRoom(
        appID: YourSecret.appID,
        appSign: YourSecret.appSign,
        userID: userID,
        userName: 'user_$userID',
        roomID: roomID,

        // Modify your custom configurations here.
        config: (isHost
            ? ZegoUIKitPrebuiltLiveAudioRoomConfig.host()
            : ZegoUIKitPrebuiltLiveAudioRoomConfig.audience())
          ..backgroundMedia.path =
              isHost ? 'https://xxx.com/xxx.mp3' : '',
      ),
    );
  }
}

Using UI to control playback status

If you want to control the playback status yourself, you can add some simple buttons and call relevant APIs to achieve it.

Use ZegoUIKitPrebuiltLiveAudioRoomController().media.pickFile to let the user choose a local media file or use ZegoUIKitPrebuiltLiveAudioRoomController().play to play a network media file directly.
Use ZegoUIKitPrebuiltLiveAudioRoomController().play/pause/resume/stop and other APIs to control the playback status.

class LivePage extends StatefulWidget {
  final String roomID;
  final bool isHost;

  const LivePage({
    Key? key,
    required this.roomID,
    this.isHost = false,
  }) : super(key: key);

  @override
  State<StatefulWidget> createState() => LivePageState();
}

class LivePageState extends State<LivePage> {
  @override
  Widget build(BuildContext context) {
    return SafeArea(
      child: ZegoUIKitPrebuiltLiveAudioRoom(
        appID: YourSecret.appID,
        appSign: YourSecret.appSign,
        userID: userID,
        userName: 'user_$userID',
        roomID: roomID,
        // Modify your custom configurations here.
        config: isHost
            ? ZegoUIKitPrebuiltLiveAudioRoomConfig.host()
            : ZegoUIKitPrebuiltLiveAudioRoomConfig.audience()
          ..foreground = simpleMediaPlayer(

Media player

Of course, we also provide an encapsulated media player for your convenience.

Below is an example of watching movies together, demonstrating how to use the media player.:

Untitled

class LivePage extends StatelessWidget {
  const LivePage({Key? key, required this.roomID, this.isHost = false})
      : super(key: key);

  final String roomID;
  final bool isHost;

  @override
  Widget build(BuildContext context) {
    return SafeArea(
      child: LayoutBuilder(
        builder: (context, constraints) {
          return ZegoUIKitPrebuiltLiveAudioRoom(
            appID: YourSecret.appID,
            appSign: YourSecret.appSign,
            userID: userID,
            userName: 'user_$userID',
            roomID: roomID,

            // Modify your custom configurations here.
            config: (isHost
                ? ZegoUIKitPrebuiltLiveAudioRoomConfig.host()
                : ZegoUIKitPrebuiltLiveAudioRoomConfig.audience())
              ..foreground = advanceMediaPlayer(
                constraints: constraints,
                canControl: isHost,
              ),
          );
        },
      ),
    );
  }

  Widget advanceMediaPlayer({
    required BoxConstraints constraints,
    required bool canControl,
  }) {
    const padding = 20;
    final playerSize =
        Size(constraints.maxWidth - padding * 2, constraints.maxWidth * 9 / 16);
    return ZegoUIKitMediaPlayer(
      size: playerSize,
      enableRepeat: true,
      canControl: canControl,
      showSurface: true,
      initPosition: Offset(
        constraints.maxWidth - playerSize.width - padding,
        constraints.maxHeight - playerSize.height - padding - 40,
      ),
    );
  }
}
