  22 mai 2019, par Doro

  I trying to stream 2 files - 1.mkv without audio (which streaming ok) and 2.mkv with audio encoded with Vorbis codec which i can’t stream. For encoding I used

  ffmpeg -i 2.mp4 -strict -2 -c:a vorbis ex.mkv 

  And it playing ok with ffplay

• Video file not trimming and copying using FFMpeg in C#

  15 mai 2019, par chapperzuk

  I am trying to clip a video using C# in Visual Studios with FFMpeg. I run the code below and it doesn’t come back with any errors, except it doesn’t create a new video file.

  I’ve looked around here to make sure I’m using the correct code, but after multiple attempts it still won’t copy.

  string videoFile = @"C:\Users\dave\Documents\video 1.mp4";
  
  string outputFile = @"C:\Users\dave\Documents\video 2.mp4";
  
  
  
  Process process = new Process();
  
  process.StartInfo.RedirectStandardOutput = true;
  
  process.StartInfo.RedirectStandardError = true;
  
  process.StartInfo.FileName = @"C:\Users\dave\Documents\ffmpeg.exe";
  
  process.StartInfo.Arguments = "ffmpeg -i " + videoFile + " -ss 00:30:00 -t 00:00:10 -c copy " + outputFile;
  
  process.StartInfo.UseShellExecute = false;
  
  process.StartInfo.CreateNoWindow = true;
  
  process.Start();

  I was expecting to get a video cut from the original video, starting at the 30 second mark and lasting 10 seconds, but nothing is created.

  I am using the latest FFMpeg from https://ffmpeg.zeranoe.com/builds/

  UPDATE If I run the code in command prompt - The file comes out corrupt though

  ffmpeg -i "C:\\Users\\dave\\Documents\\video 1.mp4" -ss 00:30:00 -t 00:00:10 -c copy "C:\\Users\\dave\\Documents\\video 2.mp4"

  What I trying to do is, save video :

  require '/vendor/autoload.php';
  
  $ffmpeg = FFMpeg\FFMpeg::create();
  
  $ffprobe = FFMpeg\FFProbe::create();
  
  $video = $ffmpeg->open('Sample.mp4');
  
  $video
  
      ->filters()
  
      ->resize(new FFMpeg\Coordinate\Dimension(320, 240))
  
      ->synchronize();
  
  $video
  
      ->save(new FFMpeg\Format\Video\X264('aac'), 'export-x264.mp4')

  What I have done :

  I searched and similar topics tell me to set permission to my files and folders, I set user and also set 755 to files and folders but still I have this error and no success, any idea ?
