C# FFMPEG Process and Multiple files
23 novembre 2023, par wesmanI am working on a C# Form tool that will help me convert all of my phone and DSLR video to HEVC, currently, i have a program that uploads the photos and videos to different directories in my home server each time i connect to the WiFi. Once a month or so, i manually convert all the videos, but thought I would automate the process.. I have the Form working perfectly for processing 1 file. but get into trouble when processing a Directory (with possible sub-directories) all at once..



Sorry, this is long, just want to be thorough. here is the button calls



private void processFile_Click(object sender, EventArgs e)
 {
 OpenFileDialog file = new OpenFileDialog();
 file.InitialDirectory = baseMediaDirectory;
 if (file.ShowDialog() == DialogResult.OK)
 {
 ProcessSinlgeFile(file.FileName);
 }
 }



(above)for one file and (below) for a directory



private void processDirectory_Click(object sender, EventArgs e)
{
 FolderBrowserDialog file = new FolderBrowserDialog();
 file.SelectedPath = baseMediaDirectory;
 if(file.ShowDialog() == DialogResult.OK)
 {
 ProcessDirectoryOfFiles(file.SelectedPath);
 }
}

private void ProcessDirectoryOfFiles(string selectedPath)
 {
 List<string> listOfFiles = GetAllFiles(selectedPath);
 foreach (string s in listOfFiles)
 {
 ProcessSinlgeFile(s);
 }
 }
</string>


both ultimately call this method, to do some checks and setup



private void ProcessSinlgeFile(string fileName)
 {

 if (IsAcceptableMediaFile(fileName))
 {
 outputWindow.AppendText("File to Process: " + fileName);
 processMediaFile = 
 new MediaFileWrapper(this.outputWindow, new MediaFile(fileName), new NReco.VideoInfo.FFProbe());
 if (processMediaFile.OkToProcess)
 {
 int initialCRFValue = 15;
 //ultrafast superfast veryfast faster fast medium slow slower veryslow placebo
 string intialSpeed = "veryfast";
 try {

 ConvertToMPEG(processMediaFile.getFFMPEGCommand(initialCRFValue, intialSpeed), processMediaFile);
 }
 catch
 {
 // at somepoint, we'll catch a bad file size (or compression)
 // then change the CRF value and/or compression speed
 }
 }
 }
 }



ultimately I get to this Method and run into trouble.



private async void ConvertToMPEG(string arguments, MediaFileWrapper processMediaFile)
 {
 startTime = DateTime.Now;
 watch = new Stopwatch();
 watch.Start();
 progressBar1.Minimum = 0;
 progressBar1.Maximum = processMediaFile.GetTotalMilliseconds();

 // Start the child process.
 p = new Process();

 //Setup filename and arguments
 outputWindow.AppendText("ffmpeg " + arguments);
 p.StartInfo.Arguments = arguments;
 p.StartInfo.FileName = "ffmpeg.exe";
 p.StartInfo.UseShellExecute = false;

 // Redirect the output stream of the child process.
 p.StartInfo.RedirectStandardOutput = true;
 p.StartInfo.RedirectStandardError = true;
 p.StartInfo.RedirectStandardInput = true;

 // capture the date for stdout and std error
 // note FFMPEG uses Stderr exclusively
 p.ErrorDataReceived += new DataReceivedEventHandler(ErrorDataReceived);
 p.OutputDataReceived += new DataReceivedEventHandler(OutputDataReceived);

 // Hide Console Window
 p.StartInfo.CreateNoWindow = true;
 p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;

 p.Start();
 p.BeginErrorReadLine();
 p.BeginOutputReadLine();
 await p.WaitForExitAsync();
 }



and WaitForExitAsync is in another class because in can not be in here with a Form



public static Task WaitForExitAsync(this Process process,
 CancellationToken cancellationToken = default(CancellationToken))
 {
 var tcs = new TaskCompletionSource();
 process.EnableRaisingEvents = true;
 process.Exited += (sender, args) => tcs.TrySetResult(null);
 if (cancellationToken != default(CancellationToken))
 cancellationToken.Register(tcs.SetCanceled);

 return tcs.Task;
 }



however, single files work fine, when I call a directory through, it continuously starts processes for each file, trying to run them all at the same time. You can see I tried implementing this 
process.WaitForExit() asynchronously
with no luck.
