• FFmpeg 0.6 ; Something About HTML5

  17 juin 2010, par Multimedia Mike — Open Source Multimedia

  The FFmpeg project made a formal release yesterday. You can download version 0.6 from the project’s download page.

  I’ve actually been seeing more news items about this today than I would have expected. This is most likely because the 0.6 release is named "Works with HTML5". Let it never be said that nerds don’t know marketing. The team really latched on to the hottest buzzword going right now.

  The name of the release refers to FFmpeg’s new native support for Google’s WebM format. It can mux and demux the WebM container, and decode the Vorbis audio, all natively (FFmpeg’s Vorbis encoder has been demoted to "experimental" for this release and it is recommended to enable libvorbis for encoding). But the big news is that this release can support Google’s libvpx natively for VP8 encoding and decoding, without having to apply any other patches.

  Getting libvpx to compile still might be a bit tricky. Fortunately, the first pass of a native, independent VP8 decoder is currently in review on the ffmpeg-devel list.

• FFmpeg command for Merge audio with video not working - C#

  11 juin 2019, par nsds

  I have tried to combine a video.mp4 file with mic.wav as like below. But combined video is not generating.
  Command prompt says -

  ’ffmpeg’ is not recognized as an internal or external command,
  operable program or batch file.

  Shall I need to install ffmpeg other than Accord.Video.FFMPEG ? If then is it independent for each system the app execute ?
  Please help to correct.

  using System.Collections.Generic;
  
  using System.Runtime.InteropServices;
  
  using Accord.Video.FFMPEG;
  
  using System;
  
  public void merge()
  
  {
  
      try
  
      {
  
          // string args = "/c ffmpeg -i video.mp4 -i mic.wav -c copy -map 0:v:0 -map 1:a:0 output.mp4";
  
          // string args = "/c ffmpeg - i mic.wav - i example - video.mp4 - c:v copy -vcodec copy final.mp4";
  
          string args = $"/c ffmpeg -i video.mp4 -i mic.wav -shortest out.mp4";
  
          ProcessStartInfo startInfo = new ProcessStartInfo();
  
          startInfo.CreateNoWindow = false;
  
          startInfo.FileName = "cmd.exe";
  
          startInfo.WorkingDirectory = "E:\\Newfolder";
  
          startInfo.Arguments = args;
  
          using (Process exeProcess = Process.Start(startInfo))
  
          {
  
              exeProcess.WaitForExit();
  
          }
  
      }
  
      catch(Exception ex)
  
      {
  
          string exx = ex.ToString();
  
      }
  
  }
