专属版设备播放接口与通用版基本相同，请先阅读【通用版-音视频播放】相关接口

设备对象

专属版对象继承自通用版设备对象DeviceInfo

import com.polaris.iot.appsdk.libuserdevicemgr.model.DeviceInfo
/**
 * 专属版设备信息，播放时使用
 *
 * @param iotId 平台为设备颁发的ID，设备的唯一标识符。
 * @param productKey 产品型号唯一值
 * @param deviceName 设备序列号
 * @param isSupportP2P 是否支持P2P
 * @param lensCount 设备镜头数 默认一个镜头
 * @param deviceWorkMode 设备工作模式 默认常上电
 * @param videoCodec 设备视频编码
 * @param audioCodec 设备音频编码
 * @param isSupportCompressData 设备信令是否支持压缩数据

open class SpecialDeviceInfo(
    iotId: String,

}

播放示例

提供播放器使用示例，请先阅读【通用版-音视频播放-播放示例】

1. 请先构建专属版设备对象 可选参数isSupportP2P、lensCount、deviceWorkMode、videoCodec、audioCodec、isSupportCompress可由设备物模型上报
2. 其它同通用版音视频播放

private SpecialDeviceInfo mDeviceInfo; 

private IoTDeviceInfo iotDevice;
private IoTPlayerCtrl playerCtrl;


private void initPlayer() {
    if (mDeviceInfo == null) throw new IllegalStateException("need device info");

    if (playerCtrl == null) {
        //是否支持P2P
		boolean isSuppurtP2P = true
        //设备工作模式 
        String deviceWorkMode = "2"
        //视频编码
        String videoCodec = "H265"
        //音频编码
        String audioCodec = "G711" 
        //设备镜头数 多目设备有多个镜头
        int lensCount = 1
        
        SpecialDeviceInfo deviceInfo = SpecialDeviceInfo("{iotId}","{productKey}","{deviceName}",
                                          isSuppurtP2P,lensCount,deviceWorkMode, videoCodec,audioCodec)
        iotDevice = IoTDeviceInfo.copyFrom(mDeviceInfo);

       
        IoTPlayerViewInitParam param = new IoTPlayerViewInitParam(VideoDecodeModeEnum.HARDWARE, iotDevice);

        param.setStreamType(IoTStreamTypeEnum.MAIN);
        //IoTPlayerCtrl 的初始化
        binding.iotPlayerView.init(param);
        playerCtrl = binding.iotPlayerView.getPlayerCtrl();
        playerCtrl.setOnPlayerListener(this);
    }
    playerCtrl.prepare(new IoTPlayerParam());
    playerCtrl.start();
}
