• Linux based mp3 to wmv converter

  30 octobre 2012, par algorithmicCoder

  Is there some software library that can i can interact with via command line (no GUI business) exist that can take an mp3 and output wmv or a similar format ?

  Can ffmpeg do this ?

  I found this product—> http://www.3herosoft.com/how-to-convert-mp3-to-wmv.html ...ideally i would want to find a library that was able to carry out the same basic functionality via command line.

  Thanks !

• Image edited and saved in C# can not be read by ffmpeg

  13 juillet 2017, par mmijic

  I have template image (template.jpg) on which I draw some text (13.07.2017.) and than I save it to another location (temp/intro.jpg).

  Than I want to convert that and some other images into video with ffmpeg.

  If I run command

  ffmpeg.exe -f concat -safe 0 -i input.txt -c:v libx264 -vf "fps=25,format=yuv420p" out.mp4

  Those images gets concentrated into one video file. Problem is that this image edited through C# is black in final video.

  If I for example open that C# created image in Adobe Fireworks and just save it (CTRL+S) without changing anything, and re run ffmpeg command everything is fine.

  This is code which I use to add text to template image

  //INTRO IMAGE CREATION
  
  Bitmap image = new Bitmap(1280, 720);
  
  image.SetResolution(image.HorizontalResolution, image.VerticalResolution);
  
  Graphics g = Graphics.FromImage(image);
  
  g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;
  
  g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;
  
  g.PixelOffsetMode = System.Drawing.Drawing2D.PixelOffsetMode.HighQuality;
  
  g.TextRenderingHint = TextRenderingHint.AntiAliasGridFit;
  
  StringFormat format = new StringFormat()
  
  {
  
      Alignment = StringAlignment.Near,
  
      LineAlignment = StringAlignment.Near
  
  };
  
  
  
  //template
  
  Bitmap back = new Bitmap(Application.StartupPath + @"\Templates\template.jpg");
  
  g.DrawImage(back, 0, 0, image.Width, image.Height);
  
  
  
  //date
  
  string Date = dateIntro.Value.ToString("dd.MM.yyyy.");
  
  var brush = new SolidBrush(Color.FromArgb(255, 206, 33, 39));
  
  Font font = new Font("Ubuntu", 97, FontStyle.Bold, GraphicsUnit.Pixel);
  
  float x = 617;
  
  float y = 530;
  
  
  
  g.DrawString(Date, font, brush, x, y, format);
  
  g.Flush();
  
  image.Save(Application.StartupPath + @"\temp\intro.jpg", ImageFormat.Jpeg);
  
  image.Dispose();

  Image created this way can be opened and viewed in any program except converted to video with ffmpeg.

  Is there anything I’m missing while adding text and saving image in C# ?
