• How can I use variables in long PowerShell command without breaking the command

  15 octobre 2020, par AFouquet

  I want to use ffmpeg to convert .m4a files in to .mp3 files.

  


  I can do it for each single file, but that takes a lot of effort to type in.

  


  ffmpeg -i '.\song.m4a' -ac 2 -b:a 192k '.\song.mp3'


  


  Is there a way to do this with powershell using variables ?
ex :

  


  ffmpeg -i $v -ac 2 -b:a 192k $v.mp3


  


  The problem with this is that then the -ac flag is taken as part of the path and not of ffmpeg anymore.

  


  Is there a way around this in powershell ?
  
Or could this be done with an array ? If I use $v=Get-ChildItem -Name and iterate over the array with a foreach loop in to the ffmpeg command.

  


  I am very new to PowerShell and don't have a lot of experience but it seems to me that should be possible to do.

  


  I would appreciate any help I can get.

  I'm trying to run an extremely long ffmpeg command but I end up getting an unusual error. I have the following command in a .cmd file :

Invalid duration specification for to: 00:0011


  


  I don't really understand what's going wrong here ; if you look at the input ffmpeg command, you'll see that there is no -to flag immediately followed by 00:0011 as the error message claims (scroll to the bottom). When I run that particular trim on the file in question separately, it is able to trim it just fine. You can also see that the input file is used prior to input #86 and doesn't receive this issue (see input #17).

  


  My only thought is that it has something to do with the command itself being so long. Is it possible that ffmpeg is not able to parse the command correctly because it is so long ? I'm on Windows 10 with ffmpeg version ffmpeg version 2021-07-14-git-ca56299fb3-full_build-www.gyan.dev. I get the same issue in both powershell and cmd. I am running it from a .cmd file because Windows won't let me run it from command line directly because it is longer than 8192 characters.

  


• Load first generated dynamic control then load next

  13 juillet 2015, par prasanas

          private void AddControls(int ControlNumber) {
  
          HtmlGenericControl divContent = new HtmlGenericControl("div");
  
          divContent.ID = "Panel";
  
          divContent.Attributes.Add("class", "div");
  
          UpdatePanel1.ContentTemplateContainer.Controls.Add(divContent);
  
          System.Threading.Thread.Sleep(1000);
  
          }

  Why i am adding system.thread because instead of wait command we are using ffmpeg convertor to generate thumnails of video’s it takes around 2 seconds for each video file.

  Consider there are 5 video files. The div takes 10 seconds to load. The whole page gets stucked and after loading all 5 videos we can see it.

  Is there a way like updatepanel or some other to load each file and load next.

      </contenttemplate>

  c# Code :

      public List<string> DynamicControls {
  
          get { return (List<string>)Session["DynamicControls"]; }
  
          set { Session["DynamicControls"] = value; }
  
          }
  
  
  
      protected void Page_Init(object sender, EventArgs e) {
  
          if (!IsPostBack) {
  
              DynamicControls = new List<string>();
  
              DynamicControls.Add(AddControls(NextControl));
  
              }
  
          else {
  
              for (int i = 0; i &lt; 5; i++) {
  
                  AddControls(i);
  
                  }
  
              }
  
          }
  
  
  
      protected void Page_Load(object sender, EventArgs e) { }
  
      protected void btnAddNext_Command(object sender, CommandEventArgs e) { }
  
  
  
      public int NextControl {
  
          get { return ViewState["NextControl"] == null ? 0 : (int)ViewState["NextControl"]; }
  
          set { ViewState["NextControl"] = value; }
  
          }
  
  
  
      private string AddControls(int ControlNumber) {
  
          //add textbox
  
          TextBox txtValue = new TextBox();
  
          txtValue.ID = "txtValue" + ControlNumber;
  
          PlaceholderControls.Controls.Add(txtValue);
  
  
  
          //add button
  
          Button btnAddNext = new Button();
  
          btnAddNext.Text = "Add Control " + ControlNumber;
  
          btnAddNext.ID = "btnAddNext" + ControlNumber;
  
          int NextControl = ControlNumber + 1;
  
          btnAddNext.CommandArgument = NextControl.ToString();
  
  
  
          btnAddNext.Command += new CommandEventHandler(btnAddNext_Command);
  
          PlaceholderControls.Controls.Add(btnAddNext);
  
  
  
          //add a line break
  
          PlaceholderControls.Controls.Add(new LiteralControl("<br />"));
  
          System.Threading.Thread.Sleep(1000);
  
          return btnAddNext.UniqueID;
  
          }
  
  </string></string></string>

  For above code is sample it loads after 5 seconds loading all 5 elements. I want to load like 1sec- 1 element then 2Seconds load 2nd like this..at 5th second load 5 element.
