51工具盒子一、前言
视频监控内核组件重构和完善花了一年多时间，整个组件个人认为设计的最好的部分就是各种结构体参数的设计，而且分门别类，有枚举值，也有窗体相关的结构体参数，解码相关的结构体参数，同时将部分常用的结构体参数的获取和设置单独提供了函数，参阅海康大华等大厂的sdk的设计方式，也是将众多的参数统一归类的不同的结构体中，这样后期非常容易就能拓展，比如又新增一个参数，只需要动结构体就行，但是也有个不完美的地方就是，如果没有提供单独的参数设置接口，需要先获取之前的结构体参数，然后在此基础上修改，最后重新设置，因为如果你没有先获取再更新最后设置，而是重新定义了一个结构体参数，则很可能会把之前设置好的结构体参数覆盖掉。
窗体结构体参数设计如下：
//窗体参数
struct WidgetPara {
int borderWidth; //边框大小
QColor borderColor; //边框颜色
QColor focusColor; //焦点颜色
QColor bgColor; //背景颜色
QColor textColor; //文字颜色
QColor fillColor; //填充颜色
int bgTextSize; //文字大小
QString bgText; //背景文字
QImage bgImage; //背景图片
QString videoFlag; //视频通道标识
ScaleMode scaleMode; //缩放显示模式
VideoMode videoMode; //视频显示模式
DrawMode osdDrawMode; //标签绘制模式
DrawMode graphDrawMode; //图形绘制模式
int soundValue; //默认音量大小
bool soundMuted; //默认静音状态
bool sharedData; //共享解码线程
bool copyImage; //是否拷贝图片
bool restartClear; //重连清空画面
bool bannerEnable; //悬浮条是否启用
int bannerSize; //悬浮条尺寸大小(横向则表示高度/纵向表示宽度)
BannerPosition bannerPosition;//悬浮条位置
WidgetPara() {
borderWidth = 1;
borderColor = Qt::transparent;
focusColor = "#22A3A9";
bgColor = Qt::transparent;
textColor = Qt::transparent;
fillColor = Qt::transparent;
//fillColor = Qt::black;
bgTextSize = 25;
bgText = "视频";
bgImage = QImage();
//bgImage = QImage(":/image/bg_novideo.png");
videoFlag = "";
scaleMode = ScaleMode_Auto;
videoMode = VideoMode_Hwnd;
osdDrawMode = DrawMode_Cover;
graphDrawMode = DrawMode_Cover;
soundValue = 100;
soundMuted = false;
sharedData = false;
copyImage = false;
restartClear = true;
bannerEnable = false;
bannerSize = 25;
bannerPosition = BannerPosition_Top;
}
};
视频采集结构体参数设计如下：
//视频采集参数
struct VideoPara {
VideoCore videoCore; //解析内核
QString videoUrl; //视频地址
QString bufferSize; //缓存分辨率
int frameRate; //视频帧率
DecodeType decodeType; //解码速度策略
QString hardware; //硬件加速名称
QString transport; //通信协议(tcp udp)
int caching; //缓存时间(默认500毫秒)
bool audioLevel; //开启音频振幅
bool decodeAudio; //解码音频数据
bool playAudio; //解码播放声音
bool playRepeat; //重复循环播放
int openSleepTime; //打开休息时间(最低1000 单位毫秒)
int readTimeout; //采集超时时间(0=不处理 单位毫秒)
int connectTimeout; //连接超时时间(0=不处理 单位毫秒)
VideoPara() {
videoCore = VideoCore_None;
videoUrl = "";
bufferSize = "0x0";
frameRate = 0;
decodeType = DecodeType_Fast;
hardware = "none";
transport = "tcp";
caching = 500;
audioLevel = false;
decodeAudio = true;
playAudio = true;
playRepeat = false;
openSleepTime = 3000;
readTimeout = 0;
connectTimeout = 500;
}
void reset() {
videoUrl = "";
bufferSize = "0x0";
frameRate = 0;
}
};
