Issue In Recording Video

I am trying to record video in 480*480 resolution like in vine using javacv. As a starting point I used the sample provided in https://github.com/bytedeco/javacv/blob/master/sample

Solution 1:

To begin with, it's pre-processing, not post-processing the video.

I don't know what changes you need to tune the solution for new version of javacv, I hope they keep the library backwards compatible.

Your buffer is 640 pixels wide, and 480 pixels high. You want to crop out 480x480.

This means that you need a loop that will copy every line to the IplImage, something like this:

privateintimageWidth=640;
privateintimageHeight=480;
privateintdestWidth=480;

@OverridepublicvoidonPreviewFrame(byte[] data, Camera camera) {

if (data.length != imageWidth*imageHeight) {
    Camera.Sizesz= camera.getPreviewSize();
    imageWidth = sz.width;
    imageHeight = sz.height;
    destWidth = imageHeight;
}

ByteBufferbb= (ByteBuffer)yuvImage.image[0].position(0); // resets the bufferintstart=2*((imageWidth-destWidth)/4); // this must be evenfor (int row=0; row<imageHeight*3/2; row++) {
    bb.put(data, start, destWidth);
    start += imageWidth;
}
recorder.record(yuvImage);
