Java VM Crashed when I create FFmpegFrameRecorder obj...

[GoogleCodeExporter]

What steps will reproduce the problem?
1.download ffmpeg libraries from here: 
http://ffmpeg.zeranoe.com/builds/win32/shared/ffmpeg-0.7.1-win32-shared.7z
2.try to create a new recorder instance by : FFmpegFrameRecorder recorder = new 
FFmpegFrameRecorder ("c:\\output.avi", 320,240); 
3.An unexpected error has been detected by Java Runtime Environment...

What is the expected output? What do you see instead?
no error should be expected...
but I saw EXCEPTION_ACCESS_VIOLATION error.

#
# An unexpected error has been detected by Java Runtime Environment:
#
#  EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x649f403a, pid=7260, tid=6236
#
# Java VM: Java HotSpot(TM) Client VM (11.3-b02 mixed mode windows-x86)
# Problematic frame:
# C  [avformat-52.dll+0xb403a]
#

What version of the product are you using? On what operating system?
newest version of opencv,javacv... Try the demo "HoughLines" and it works fine.

Please provide any additional information below.
Maybe I should compile a ffmpeg library myself? what version should I use? 
Could  Samuel please give some more examples about your ffmpeg-java-wrapping 
lib?

full code is simple...

public class TestRecording {
    public static void main(String[] s) throws Exception{
        OpenCVFrameGrabber grabber = new OpenCVFrameGrabber(0);
        FFmpegFrameRecorder recorder = new FFmpegFrameRecorder 
                ("c:\\output.avi", 320,240); 
                grabber.start();
                recorder.start();
    }
}

After I delete the "FFmpegFrameRecorder" line, program run just fine...

I compiled the latest release using those binaries for FFmpeg 0.7.1, so it 
should work now! Thanks for reporting

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
