  25 juillet 2018, par MoonTech

  Hello I created one form for creating video from one mp3 file and one jpg file.
  For this I Wrote this Code but this is not the answer.

   private void button2_Click(object sender, EventArgs e)
  
      {         
  
          string input_audio = @"C:\Users\...\Desktop\test\audio";        
  
  
  
          string outPut = @"C:\Users\...\Desktop\test\outputvideo";
  
          string img= @"C:\Users\...\Desktop\folder image\image123";
  
  
  
          stripAudioTest(img, input_audio,  outPut);
  
  
  
      }
  
  
  
      public void stripAudioTest(string image, string AudioFile, string outputfile)
  
      {
  
          string FFMPEG_PATH = "ffmpeg.exe";          
  
  
  
          string strParam = "-loop 1 -i "+ image+".jpg  -i "+ AudioFile+ ".mp3 -c:v libx264 -c:a aac -strict experimental -b:a 128k -shortest "+ outputfile+ ".mp4";                    
  
  
  
          process(FFMPEG_PATH, strParam);
  
  
  
      }
  
  
  
      public void process(string Path_FFMPEG, string strParam)
  
      {
  
          try
  
          {
  
              Process ffmpeg = new Process();
  
              ffmpeg.StartInfo.UseShellExecute = false;
  
              ffmpeg.StartInfo.RedirectStandardOutput = true;              
  
              ffmpeg.StartInfo.CreateNoWindow = true;
  
              ffmpeg.StartInfo.FileName = Path_FFMPEG;
  
              ffmpeg.StartInfo.Arguments = strParam;               
  
              ffmpeg.Start();
  
              ffmpeg.StartInfo.ErrorDialog = true;             
  
              ffmpeg.WaitForExit();
  
  
  
          }
  
          catch (Exception ex)
  
          {
  
              MessageBox.Show(ex.Message);
  
          }
  
      }

  FYI : mp3 file Duration 5 minutes and 23 Seconds .
  1. I am new in FFmpeg so I don’t have idea how to get out of this.
  2. I Got ffmpeg command from Here
  3. I tried Few of more ffmpeg command .Please check it below.

  string strParam = "-y -stream_loop -1 -i " + image + ".jpg -i " + AudioFile + ".mp3 -y -r 25 -b 2500k - acodec ac3 - ab 384k - vcodec mpeg4 " + outputfile+".mp4";

  another one

  string strParam = "-loop 1 -i " + image + ".jpg -i " + AudioFile+ ".mp3 -c:v libx264 -tune stillimage -c:a aac -strict experimental -b:a 192k -pix_fmt yuv420p -shortest " + outputfile+".mp4";

  I am using an IP camera with rtsp stream to do motion detection. When a motion happens, I want to use ffmpeg to record a video clip with 20 seconds before and 20 seconds after motion happened. Please show me how I should do that use ffmpeg. Thanks.

  


• ffmpeg unrecognized file type

  1er février 2019, par user892134

  I’m using Mac OS and ffmpeg. I’m attempting to convert mp3 to mp4 with image background and overlay audio visualization.
  The below works when converting mp3 to mp4 with image :

  $mp3 = "/Users/vanessa/Downloads/test/Marco.mp3";
  
      $image = "/Users/vanessa/Downloads/test/maxresdefault.jpg";
  
      $video = "/Users/vanessa/Downloads/test/videos/test2.mp4";
  
  
  
    exec("/usr/local/Cellar/ffmpeg/4.1_3/bin/ffmpeg -loop 1 -i $image -i $mp3 -c:v libx264 -c:a aac -strict experimental -b:a 192k -shortest $video 2>&1",$output); 

  I can successfully play test2.mp4. When i attempt to do add an overlay of audio visualization. I can see in get info how it looks in the preview section but when i click on the file it says : File open error:Unrecognized file type

  exec("/usr/local/Cellar/ffmpeg/4.1_3/bin/ffmpeg -y -i $mp3 -loop 1 -i $image -filter_complex '[0:a]showwaves=s=1280x175:colors=White:mode=line,format=yuv420p[v];[1:v][v]overlay=0:200[outv]' -map '[outv]' -pix_fmt yuv420p -map 0:a -c:v libx264 -c:a copy -shortest $video 2>&1",$output); 

  Where did i go wrong ? The player i’m using is Quicktime.
