• How can I record the desktop action to a video file with ffmpeg without showing the ffmpeg console window ?

  24 décembre 2018, par Dubi Duboni

  Tried this method either by calling it from the constructor or a button click event :

  private void StartRecordingDesktop()
  
          {
  
              Process process = new Process();
  
  
  
              // Stop the process from opening a new window
  
              process.StartInfo.RedirectStandardOutput = true;
  
              process.StartInfo.UseShellExecute = false;
  
              process.StartInfo.CreateNoWindow = true;
  
              process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
  
  
  
              // Setup executable and parameters
  
              process.StartInfo.FileName = @"d:\SavedScreenshots\ffmpeg.exe";
  
              process.StartInfo.Arguments = "-f gdigrab -framerate 24 -i desktop -preset ultrafast -pix_fmt yuv420p testwithforms.mp4";
  
  
  
              // Go
  
              process.Start();
  
          }

  Two problems :

  1. It’s not recording when I shut down the application there is no video file on the hard disk.

  2. When I shut down the application sometimes it leaves a working exe file parto f the ffmpeg in the background that make the mouse cursor to shake a bit stuttering.

  What I want is to start/stop recording without showing the ffmpeg console window. The idea in the end is to make some identification of the recording mode if recording or not using a tray icon as indiacator.

• What are the alternatives of PHP-ffmpeg and LaravelFFMpeg repo

  24 juin 2019, par Sirsemy

  I use Laravel and PHP. I’d convert video during streaming, and I’d like to put watermark to the video.
  I spent days to try to set up the pascalbaljetmedia/laravel-ffmpeg repo from GitHub and try to use PHP-ffmpeg but I couldn’t.

  Are there any alternative for the same usage ?

  I use

  • Laravel 5.8
  • PHP 7.1
  • Windows 10
  • Wamp server

  Thanks for the help in advance.

  Edit

  We’ve used this code for call an external ffmpeg but that also haven’t worked.

      $ffmpeg = "c:\\ffmpeg\bin\\ffmpeg.exe";
  
      $cmd = $ffmpeg . " -i " . $videoPath . " -i " . $watermark . " -filter_complex 'overlay' " . $saveLocation;
  
      exec($cmd, $output);

  Created the video but didn’t use the filter what the repo mention.

• The appearance of silence time at the end when the -r is too small

  14 juin 2023, par Kazbekuri

  I have one mp3 and one picture I want to make mp4 and put this picture in the background, so that the rendering is very fast, because it is just a picture and do not want to put a lot of fps (weak pc), but there is a problem which is the appearance of silence time after the audio information. If I put more -r then everything is solved, but I need an alternative way to make it work fast and without typing different parameters like -t.

  


  My command :
ffmpeg -loop 1 -r 1 -i peg.jpeg -i ex.mp3 -c:a aac -b:a 320K -strict -2 -shortest -fflags +shortest -max_interleave_delta 100M video.mp4

  


  I tried "-max_muxing_queue_size 9999" but that didn't work for me. I also tried -fflags+shortest -max_interleave_delta 100M. This helped me a little, but not enough.
