ApsaraVideo Live:一般的なビデオ操作と設定

Android

ローカルカメラをミュートまたはミュート解除します:

if(!isMutedCamera) {
    mAliRtcEngine.muteLocalCamera(true, AliRtcEngine.AliRtcVideoTrack.AliRtcVideoTrackCamera);
    mPublishVideoBtn.setText(R.string.resume_pub_video);
    isMutedCamera = true;
} else {
    mAliRtcEngine.muteLocalCamera(false, AliRtcEngine.AliRtcVideoTrack.AliRtcVideoTrackCamera);
    mPublishVideoBtn.setText(R.string.stop_pub_video);
    isMutedCamera = false;
}

リモートコールバックをリッスンします:

@Override
public void onUserVideoMuted(String uid ,boolean isMute){
    handler.post(new Runnable() {
        @Override
        public void run() {
            ToastHelper.showToast(VideoBasicUsageActivity.this, "remote user uid:" + uid + " camera mute:" + isMute, Toast.LENGTH_SHORT);
        }
    });
}

iOS

カメラデータ収集を有効または無効にします:

@IBAction func onVideoMuteSwitched(_ sender: UISwitch) {
    if sender.isOn {
        // Black frames
        rtcEngine?.muteLocalCamera(false, for: AliRtcVideoTrack.camera)
    } else {
        rtcEngine?.muteLocalCamera(true, for: AliRtcVideoTrack.camera)
    }
}

リモート側でコールバックをリッスンできます:

extension VideoBasicUsageVC: AliRtcEngineDelegate {
    func onUserVideoMuted(_ uid: String, videoMuted isMute: Bool) {
        "onUserVideoMuted: user id \(uid) video muted: \(isMute)".printLog()
    }
}

Android

カメラを有効または無効にします:

mCameraSwitchBtn = findViewById(R.id.camera_control_btn);
mCameraSwitchBtn.setOnClickListener(v -> {
    if(mAliRtcEngine != null) {
        if(isEnableCamera) {
            mAliRtcEngine.enableLocalVideo(false);
            isEnableCamera = false;
            mCameraSwitchBtn.setText(R.string.camera_on);
        } else {
            mAliRtcEngine.enableLocalVideo(true);
            isEnableCamera = true;
            mCameraSwitchBtn.setText(R.string.camera_off);
        }
    }
});

リモートコールバックをリッスンします:

@Override
public void onUserVideoEnabled(String uid, boolean isEnable) {
    handler.post(new Runnable() {
        @Override
        public void run() {
            ToastHelper.showToast(VideoBasicUsageActivity.this, "remote user uid:" + uid + " camera enable:" + isEnable, Toast.LENGTH_SHORT);
