基於螢石雲實現的九宮格影片監控效果

孔小爽發表於2024-04-25

螢石雲九宮格監控實現流程
說在最前面
將海康錄影機新增到螢石雲控制檯
開始進行開發
程式碼中所用介面
獲取accessToken
獲取裝置列表
獲取攝像頭（錄影機的通道）列表
獲取當前攝像頭的監控地址
實現完整程式碼
展示效果（出於隱私不顯示影片）
額外總結
1、上、下、左、右、放大、縮小是用來操作球機或者可以進行操作的攝像機，截圖和全屏顯示功能均可使用；
2、獲取錄影機下的通道列表，每一條資訊中的`status`為`1`時，代表此通道有攝像機，為`-1`時，代表此通道未連線攝像機；
3、`ipcSerial`欄位的說明
4、上面程式碼說明

說在最前面

本筆記使用的攝像頭為海康攝像頭，攝像頭連線的是海康錄影機。小於等於9個攝像機可以直接使用。

將海康錄影機新增到螢石雲控制檯

在螢石雲開放平臺建立螢石雲賬號（註冊並登入）
螢石雲開放平臺連結
進入控制檯並進行將裝置進行繫結
開始進行開發

獲取accessToken

    url: '/api/lapp/token/get'
    type: 'post'
    data: {
        appKey: 應用資訊頁面的appKey,
        appSecret: 應用資訊頁面的appSecret
    }

獲取裝置列表

    url: '/api/lapp/device/list'
    type: 'post'
    data: {
        accessToken: 獲取到的accessToken,
        pageSize: 每頁多少條資料,
        pageStart: 開始頁數
    }

獲取攝像頭（錄影機的通道）列表

    url: '/api/lapp/device/camera/list'
    type: 'post'
    data: {
        accessToken: 獲取到的accessToken,
        deviceSerial: 裝置的序列號
    }

獲取當前攝像頭的監控地址

    url: '/api/lapp/v2/live/address/get'
    type: 'post'
    data: {
        accessToken: 獲取到的accessToken,
        deviceSerial: 裝置的序列號,
        channelNo: 當前攝像頭在錄影機中的通道號
    }

展示效果（出於隱私不顯示影片）

額外總結
1、上、下、左、右、放大、縮小是用來操作球機或者可以進行操作的攝像機，截圖和全屏顯示功能均可使用；
2、獲取錄影機下的通道列表，每一條資訊中的status為1時，代表此通道有攝像機，為-1時，代表此通道未連線攝像機；
3、ipcSerial欄位的說明
利用裝置序列號獲取通道列表時：
（1）status欄位為1時，且ipcSerial和deviceSerial相同時，代表當前裝置是直連的攝像頭，攝像頭的；
（2）status欄位為-1時，且ipcSerial和deviceSerial相同時，代表此通道未連線攝像機，連線螢石雲的裝置為硬碟錄影機；

4、上面程式碼說明
（1）因為我的裝置使用介面新增的，裝置列表資料庫存了一份，所以應用中沒有使用介面獲取裝置列表；
（2）程式碼中判斷當前通道是否接入攝像頭是判斷ipcSerial和deviceSerial是否相等；如果螢石雲直接連的攝像頭，需要改變判斷方式；
（3）程式碼中注掉的部分是16格影片，使用16格影片時需要解除註釋，渲染影片播放方法中的this.select=4，寬高比也應為/4。
