提供存储卡录制不同方式的播放能力

package com.polaris.iot.appsdk.libplayback

    /**
     * 按时间段获取SD卡录制文件
     *
     * @param params 请求参数 [SDCardRecordQueryReq]

按时间录制列表

时间跨度不能超过7天，开始时间不能大于结束时间

返回列表倒序排列

String iotId = ""
long endTime = System.currentTimeMillis();
long beginTime = endTime - 6 * 3600 * 1000;

final RecordQueryReq recordQueryReq = new SDCardRecordQueryReq(mPlayDeviceInfo.getProductKey(), mPlayDeviceInfo.getDeviceName(), beginTime, endTime);
SDCardService.recordTimeQuery(recordQueryReq, new OnResultListener<RecordQueryRsp>() {
    @Override
    public void onError(@NonNull IoTSDKError error) {

    }

    @Override
    public void onResult(RecordQueryRsp result) {
        final List<TimelineRecordInfo> RecordInfoList = result.getRecordFileList(); 
    }
});

按时间录制列表播放

IoTPlayerParam param = new IoTPlayerParam();
//从录制数据接口返回
boolean isSDCardPlayback = true;
IoTPlayerSeekParam seekParam = new IoTPlayerSeekParam(beginTime,endTime,isSDCardPlayback )
mPlayerCtrl.prepare(param,seekParam);
mPlayerCtrl.start();

//回看seek
IoTPlayerSeekParam seekParam = new IoTPlayerSeekParam(beginTime,endTime,isSDCardPlayback)
mPlayerCtrl.seekTo(seekParam);

按文件录制列表

时间跨度不能超过7天，开始时间不能大于结束时间

返回列表倒序排列

String iotId = ""
long endTime = System.currentTimeMillis();
long beginTime = endTime - 6 * 3600 * 1000;

SDCardRecordQueryReq recordQueryReq = new SDCardRecordQueryReq(mDeviceInfo.getProductKey(), mDeviceInfo.getDeviceName(), beginTime, endTime);
SDCardService.recordFileQuery(recordQueryReq, new OnResultListener<RecordFileQueryRsp>() {
    @Override
    public void onError(@NonNull IoTSDKError error) {

    }

    @Override
    public void onResult(RecordFileQueryRsp result) {
        List<SDCardRecordFileInfo> recordInfoList = result.getRecordFileList();
    }
});

按文件录制播放

IoTPlayerParam param = new IoTPlayerParam();
//录制文件名
String filename = ""
//播放绝对时间
long beginTime;
//录制文件结束时间（绝对时间）
long endTme;
//播放绝对时间相对于文件起始时间（绝对时间）的偏移时间
int seekPos;
IoTPlayerSeekParam seekParam = new IoTPlayerSeekParam(beginTime,endTime,filename, seekPos)
mPlayerCtrl.prepare(param,seekParam);
mPlayerCtrl.start();

//回看seek
IoTPlayerSeekParam seekParam = new IoTPlayerSeekParam(beginTime,endTime,filename, seekPos)
mPlayerCtrl.seekTo(seekParam);

录制事件列表

时间跨度不能超过7天，开始时间不能大于结束时间

返回列表倒序排列

事件播放同按时间录制列表播放

String iotId = ""
long endTime = System.currentTimeMillis();
long beginTime = endTime - 6 * 3600 * 1000;

final SDCardEventQueryReq queryReq = new SDCardEventQueryReq(mDeviceInfo.getProductKey(), mDeviceInfo.getDeviceName(), beginTime, endTime);
SDCardService.eventTimeQuery(queryReq, new OnResultListener<EventQueryRsp>() {
    @Override
    public void onError(@NonNull IoTSDKError error) {

    }

    @Override
    public void onResult(EventQueryRsp result) {
        final List<TimelineEventInfo> eventInfoList = result.getEventList();
    }
});

按月统计录制

按月查询每天是否有录制，使用场景：在日历上加小红点

示例

private void startRecordMonthQuery() throws ParseException {
    Date queryDate = getQueryBeginTime();
    Calendar calendar = Calendar.getInstance();
    calendar.setTime(queryDate);
    SDCardRecordMonthQueryReq params = new SDCardRecordMonthQueryReq(
        mDeviceInfo.getProductKey(), 
        mDeviceInfo.getDeviceName(), 
        calendar.get(Calendar.YEAR), 
        calendar.get(Calendar.MONTH) + 1
    );
    SDCardService.monthRecordQuery(params, new OnResultListener<>() {
        @Override
        public void onError(@NonNull IoTSDKError error) {
            hideLoading();
            showToast("月录制查询失败，" + error.getMessage());
        }

        @Override
        public void onResult(MonthQueryRsp result) {
            runOnUiThread(() -> {
                hideLoading();
                List<CommonListItem> list = new ArrayList<>();
                for (MonthQueryItem item : Objects.requireNonNull(result.getDayCntList())) {
                    list.add(new CommonListItem(item.getDateStr(), String.valueOf(item.getCount())));
                }
                mCommonListAdapter.setDataList(list);
                showToast("月录制查询成功");
            });
        }
    });
}
