將目前目錄頰下的所有mp4檔案進行縮小轉檔,以下為MATLAB程式碼

 1: mkdir('out');

 2: files = dir('*.mp4');

 3: bitrate = 2000;

 4: outputFolder = ['out' filesep];

 5: c1 = 'ffmpeg -i ';

 6: c2 = [' -vf scale=640:480 -threads 0 '];

 7: c3 = outputFolder;

 8: fid = fopen('batchrun.bat','w');

 9: for k=1:length(files)

首先, 新增一個專案名稱“MouseClickAndDraw”設定BackColor 屬性值為 Black color設定DoubleBuffered 為True 加入圖片至Resources

Qt 5.2
我的SONY NB Win7 64 bit選擇 Qt 5.2.0 for Windows 64-bit (VS 2012, 590 MB) (Info)

專案設定Common Language Runtime Support預設值為No Common Language Runtime Support改選擇支援Common Language Runtime(/clr)設定clr完成後編輯程式才會自動出現對應的提示字,否則會不認得namespace System及System::IO

 1: // WriteFileDemo4.cpp : Defines the entry point for the console application.

CRT(C執行時期函式庫)在編譯前須先設定preprocessor, 加入_CRT_SECURE_NO_WARNINGSCRT安全版: 增加參數驗證, 緩衝區大小檢查, 格式化參數驗證功能寫入fprintf_s讀取fscanf_s

 1: #include "stdafx.h"

 2: #include <cstdio>

 3: #include <iostream>

利用ofstream寫入檔案, ifstream讀入檔案
很明顯用標準函式庫比上一篇(Windows API WriteFile and ReadFile)使用Windows API語法簡單易懂多了!!!

使用WindowsAPI進行WriteFile 和 ReadFile應用程式  ---> Windows API –—> Windows 作業系統

 1: #include "stdafx.h"

 2: #include <Windows.h>

 3: #include <iostream>
