Record video #16

Open tuanbipa opened 7 years ago

tuanbipa commented 7 years ago

I use FFmpegFrameRecorder to record video from byte[] yuvFrame , but it seems that delayed

        byte[] bytes = new byte[yuvFrame.length];
        System.arraycopy(y, 0, bytes, 0, y.length);
        for (int i = 0; i < u.length; i++) {
            bytes[y.length + (i * 2)] = nv[i];
            bytes[y.length + (i * 2) + 1] = nu[i];
        }
        opencv_core.IplImage yuvImage1 = opencv_core.IplImage.create(width, height * 3 / 2, IPL_DEPTH_8U, 1);
                yuvImage1.getByteBuffer().put(bytes);
                opencv_core.IplImage bgrImage = opencv_core.IplImage.create(width, height, IPL_DEPTH_8U, 3);
                cvCvtColor(yuvImage1, bgrImage, CV_YUV2BGR_NV21);
                Bitmap modifiedBitmap = IplImageToBitmap(bgrImage);
                org.bytedeco.javacv.AndroidFrameConverter converter = new AndroidFrameConverter();
                Frame modifiedFrame = converter.convert(modifiedBitmap);
                recorder.record(modifiedFrame);

what is solution for recording?
