The code is as follows :

import com.googlecode.javacv.cpp.opencv_core;
public class VideoRecorderDemo
{
OpenCVFrameGrabber grabber;
FFmpegFrameRecorder recorder;
CanvasFrame canvasFrame;
VideoRecorderDemo()
{
grabber = new OpenCVFrameGrabber("c:\\sample.mp4");
recorder = new FFmpegFrameRecorder("c:\\sample1.mp4", 2);
canvasFrame = new CanvasFrame("Video Recorder Demo");
canvasFrame.setDefaultCloseOperation(javax.swing.JFrame.EXIT_ON_CLOSE);
try
{

I am using OpenCV 2.4.3 libs and the ffmpeg libs provided from zeronoe (ffmpeg-20130209-git-969039e-win64-shared)
Thanks

Answer 1

u must use this version of ffmpeg:
http://ffmpeg.zeranoe.com/builds/win64/shared/ffmpeg-20121029-git-11d695d-win64-shared.7z
i had ur problem but i searched the JavaCV readme file and i found that JavaCV has been compiled with this version of ffmpeg
good luck
