• Extract Motion Vectors From x264 source code

  27 mai 2021, par Essam Aly

  If you are familiar with the x264 source code, where in the code I can extract the MV (motion vectors) of each frame ? Can you point please to a line of code I can intercept and save the MVs to disk ?
Thank you.

• Porting code from Windows 7 to Linux using using NReco.VideoConverter

  2 février 2017, par Omar Salem

  I trying to port code from Windows 7 to Linux (RHEL 7). I am using the component to connect to a webcam and capture audio and video to a file and also capture frames as images to files. On Windows 7 I used the following code which works :

  var ffMpegTask = videoConv.ConvertLiveMedia(
  
      @"/dev/video0", // @"video=Logitech ... :audio=Microphone ..." on Windows
  
      "v4l2",                       // "dshow"  on Windows
  
      rawBmpOutputStream,
  
      null,               
  
      new ConvertSettings() {
  
              CustomOutputArgs = String.Format(" -r 5 -t 10 output.wmv -r 5 -t 10 output.mp3 -r 5 -t 10 -f rawvideo -s {0}x{1} -pix_fmt bgr24 ",
  
                      outputWidth, outputHeight)  });    

  This code compiles and executes on RHEL and MonoDevelop but does not generate the audio, video or image files. The webcam blinks for a second and goes away.
