電腦代碼視頻文件代碼

A. 怎麼查尋網頁上視頻的源代碼

方法一、在源代碼中搜索視頻格式為FLV、MP4等視頻格式，可以找到視頻文件的絕對路徑或相對路徑，將其復制到下載工具中就可以下載了。

方法二、有的視頻在源代碼中是直接找不到的，他們是通過播放器調用JS代碼中的視頻地址，這種情況就要找到被調用的JS代碼，在JS代碼裡面就可以搜索到視頻文件的地址。

方法三、還有一種情況是頁面嵌入的另外一個視頻播放頁面，需要找到另外一個頁面的源代碼，在其中去搜索視頻地址。

總之要根據實際情況去分析視頻地址隱藏於何處，找到它就可以下載了。

拓展資料：

源代碼主要有以下2種作用：

生成目標代碼，即計算機可以識別的代碼。

對軟體進行說明，即對軟體的編寫進行說明。

為數不少的初學者，甚至少數有經驗的程序員都忽視軟體說明的編寫，因為這部分雖然不會在生成的程序中直接顯示，也不參與編譯。但是說明對軟體的學習、分享、維護和軟體復用都有巨大的好處。因此，書寫軟體說明在業界被認為是能創造優秀程序的良好習慣，一些公司也硬性規定必須書寫。

（需要指出的是，源代碼的修改不能改變已經生成的目標代碼。如果需要目標代碼做出相應的修改，必須重新編譯。 ）

版權

如果按照源代碼類型區分軟體，通常被分為兩類：自由軟體和非自由軟體。自由軟體一般是不僅可以免費得到，而且公開源代碼；相對應地，非自由軟體則是不公開源代碼。所有一切通過非正常手段獲得非自由軟體源代碼的行為都將被視為非法。

B. 電腦文件類型代碼

Windows系統文件類型概覽[推薦]

大家知道，Windows系統文件按照不同的格式和用途分很多種類，為便於管理和識別，在對文件命名時，是以擴展名加以區分的，即文件名格式為: "主文件名.擴展名"。這樣就可以根據文件的擴展名，判定文件的種類，從而知道其格式和用途。例如：

"文件名1.DOC"的擴展名"DOC"表示本文件是一個"Microsoft Word 文檔"，
"文件名2.XLS"的擴展名"XLS"表示本文件是一個"Microsoft Excel 工作表"，
"文件名3.BMP"的擴展名"BMP"表示本文件是一個"BMP格式圖像"，
"文件名4.MP3"的擴展名"MP3"表示本文件是一個"MP3 格式聲音"，
"文件名5.MPEG"的擴展名"MPEG"表示本文件是一個"電影文件(MPEG)"。
