• AForge.Video.FFMPEG used in C#

  17 janvier 2017, par cuong nguyen

  I use Visual C# 2008 and want to write AVI file from bmp sequences.

  I found AForge.Video.VWF but it’s just for "vmw3" or "DIB " codecs and I want to use AForge.Video.FFMPEG but it got error.

  For example I just code :

  using System;
  
  using System.Collections.Generic;
  
  
  
  using System.Linq;
  
  using System.Text;
  
  using AForge.Video.FFMPEG;
  
  
  
  namespace ConsoleApplication4
  
  {
  
      class Program
  
      {
  
          static void Main(string[] args)
  
          {
  
              VideoFileWriter vfw = new VideoFileWriter();
  
          }
  
      }
  
  }

  But I got this filenotfoundexception

  {"The specified module could not be found. (Exception from HRESULT: 0x8007007E)":null}

• FFmpeg not encoding with libx264 library

  29 octobre 2011, par bOkeifus

  Hey people of StackOverflow. I have been having a strange issue that I'm not exactly sure what's going on. I am using FFmpeg to convert any incoming video files to h264 mp4 files using the libx264. This is the log that I get from running this line of code :

  ffmpeg -y -i vdoname.flv -acodec libfaac -vcodec libx264 -sameq vid.mp4

  This is the log output after running the line :

  FFmpeg version SVN-r13428, Copyright (c) 2000-2008 Fabrice Bellard, et al.

  Stream mapping:
  
    Stream #0.0 -> #0.0
  
    Stream #0.1 -> #0.1
  
  [libx264 @ 0x11d58b0]using cpu capabilities: MMX MMXEXT SSE SSE2 3DNow!
  
  Press [q] to stop encoding

  Can someone please help me out and tell me what to do to get this to work ? I guessed that the libx264 external library is not installed but it doesn't exactly say that in the log file and it looks as if it does find it but then doesn't actually encode the video.

  Any and all help is greatly appreciated.

• Encode loopback capture data in mp3 using ffmpeg in VC++

  16 octobre 2013, par NetCoder89

  I'm trying to work on loopback capture(What you hear) and record this file in mp3/aac format using VC++.
   >I can capture audio and can create a .wav file i.e. not compressed but I want a compressed file so I'm encoding this through ffmpeg to write an mp3 file not a .wav.

  However I'm not getting any way to do it directly ?
  I referred this for loopback capture.

  Please share your experience and opinions.

  Thanks !
