// You can speed up the conversion using the following technique: // 1) Generate video parts in parallel threads; // 2) Combine these parts into final video. // Let us say you have 20 slides. // Then you can run a thread to convert 1-10 slides and another one to convert 11-20 slides. // Finally combine these parts into a single one using .JoinWMVFiles(part1, part2, output) // or .JoingAVIFiles(part1, part2, output) functions. using System; using System.Diagnostics; using System.Runtime.InteropServices; using System.Threading; using BytescoutImageToVideo; namespace MultiThreadProcessing { class ThreadData { public string[] InputFiles; public string OutputFile; public ThreadData(string[] inputFiles, string outputFile) { InputFiles = inputFiles; OutputFile = outputFile; } } class Program { private static int _numBusy; private static ManualResetEvent _doneEvent; static void Main(string[] args) { _doneEvent = new ManualResetEvent(false); _numBusy = 2; // variable to store video file extension string sVideoFileExt; // are we using WMV or AVI video format for output bool isWMV = false; // if is WMV then use .wmv extension if (isWMV) { sVideoFileExt = ".wmv"; } else // else use AVI { sVideoFileExt = ".avi"; } // Start two conversion threads Console.WriteLine("Start first thread..."); ThreadData threadData1 = new ThreadData(new string[] { "slide1.jpg", "slide2.jpg", "slide3.jpg" }, "Part1" + sVideoFileExt); ThreadPool.QueueUserWorkItem(DoWork, threadData1); Console.WriteLine("Start second thread..."); ThreadData threadData2 = new ThreadData(new string[] { "slide4.jpg", "slide5.jpg", "slide6.jpg" }, "Part2" + sVideoFileExt); ThreadPool.QueueUserWorkItem(DoWork, threadData2); // Wait for both threads finished _doneEvent.WaitOne(); // Join generates parts Console.WriteLine("Join parts into the final video file..."); ImageToVideo converter = new ImageToVideo(); if (isWMV) { converter.JoinWMVFiles("Part1" + sVideoFileExt, "Part2" + sVideoFileExt, "Result" + sVideoFileExt); } else { converter.JoinAVIFiles("Part1" + sVideoFileExt, "Part2" + sVideoFileExt, "Result" + sVideoFileExt); } // Open the output video file in default media player Process.Start("Result" + sVideoFileExt); Console.WriteLine("Done.
