• How to incoporate ffmpeg in my audio input upload form

  3 février 2018, par Michelle Dimwaite

  this is not really a question but a request to point me to any starting direction.
  i have a simple audio upload form which stores the audio to a database or just any folder.
  I want to start by implementing ffmpeg so before this audio is stored in the folder, it goes through ffmpeg(converted to mp3 for example) and stores the converted version to the folder.
  Can someone please point me to any tutorial or links where i can start more research.
  I already installed ffmpeg.exe in xampp
  much appreciated in advance

• VB.NET : How to maintain main form control during loops in other sub ?

  5 février 2015, par Zed Machine

  I have a program with only one form.
  By pressing a button it starts a ffmpeg conversion.

  In the main form, in textboxes, ffmpeg stats are outputted. This is possible by taking StandardError output from ffmpeg.

  Public Sub Console()
  
          Dim Process As New Process 
  
  
  
          Process.StartInfo.UseShellExecute = False
  
          Process.StartInfo.RedirectStandardError = True
  
          Process.StartInfo.RedirectStandardOutput = True 
  
          Process.StartInfo.FileName = current_ffmpeg_path 
  
          Process.StartInfo.Arguments = input_params 
  
          Process.StartInfo.CreateNoWindow = True 
  
          Process.Start() 
  
  
  
          Dim ffmpeg_stats_output As System.IO.StreamReader = Process.StandardError
  
  
  
          Do While Process.HasExited = False
  
          [update all main form textboxes by taking input string from ffmpeg and elaborate it]
  
          Loop
  
  End Sub

  The problem is that while this loop is executed the textboxes and progress bar are updated but the main form cannot be modified. There is in fact no control at all by user. So if I want to make a button to stop/pause ffmpeg in main form this cannot be pressed as anything else on the main form.

  there is a way to maintain loops inside other Sub without loose control of main form while they’re running ?

  I tried to fix it by calling another dialog form with textboxes and progress bar. But even this form loose completely control until the process is finished.

  To send pause/stop conversion to ffmpeg (that runs without a window) is it correct use :

  Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
  
  SendKeys.Send("q")
  
  SendKeys.Send("^s") 
  
  End Sub

  or must be specified that this key is sent to the current running Process ?
