Does not sure how can I convert 'Image' from 'ImageReader' to 'yuv frame'

[insthync]

Hi, Now I'm developing broadcasting app which users can broadcast their screen to another users

I have try to creating new class called 'SrsScreenView' which is based on 'SrsCameraView'

I try to recording the screen by following codes

private void startRecording() {
    Log.d(TAG, "startRecording()");

    DisplayMetrics metrics = getResources().getDisplayMetrics();
    int density = metrics.densityDpi;

    if (mHandlerLoop == null)
    {
        mHandlerLoop = new Thread() {
            @Override
            public void run() {
                Looper.prepare();
                mHandler = new Handler();
                Looper.loop();
            }
        };
        mHandlerLoop.start();
    }

    // Start the video input.
    mImageReader = ImageReader.newInstance(mPreviewWidth, mPreviewHeight, PixelFormat.RGBA_8888, 2);

    mVirtualDisplay = mMediaProjection.createVirtualDisplay("Recording Display", mPreviewWidth, mPreviewHeight, density, 0 /* flags */, mImageReader.getSurface(), null /* callback */, mHandler);

    mImageReader.setOnImageAvailableListener(new ImageAvailableListener(), mHandler);
}

private class ImageAvailableListener implements ImageReader.OnImageAvailableListener {
    @Override
    public void onImageAvailable(ImageReader reader) {
        Image image = null;
        FileOutputStream fos = null;
        Bitmap bitmap = null;

        ByteArrayOutputStream stream = null;

        try {
            image = mImageReader.acquireLatestImage();
            if (image != null) {
                Image.Plane[] planes = image.getPlanes();
                ByteBuffer buffer = planes[0].getBuffer();
                int pixelStride = planes[0].getPixelStride();
                int rowStride = planes[0].getRowStride();
                int rowPadding = rowStride - pixelStride * mPreviewWidth;

                // create bitmap
                bitmap = Bitmap.createBitmap(mPreviewWidth + rowPadding / pixelStride, mPreviewHeight, Bitmap.Config.ARGB_8888);
                bitmap.copyPixelsFromBuffer(buffer);

                final Bitmap finalBitmap = bitmap;
                mActivity.runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        if (testBitmap != null)
                            testBitmap.setImageBitmap(finalBitmap);
                    }
                });
                // TODO: Have to convert bitmap/image to yuv frame
                //if (mPrevCb != null)
                //    mPrevCb.onGetYuvFrame(mYuvPreviewFrame);
            }

        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (fos != null) {
                try {
                    fos.close();
                } catch (IOException ioe) {
                    ioe.printStackTrace();
                }
            }

            if (stream != null) {
                try {
                    stream.close();
                } catch (IOException ioe) {
                    ioe.printStackTrace();
                }
            }

            if (bitmap != null) {
                //bitmap.recycle();
            }

            if (image != null) {
                image.close();
            }
        }
    }
}

I struck at where I placed todo comment, I don't know how can I convert 'Image' or 'Bitmap' to 'yuv frame', I've tested the bitmap, it's work well.

No no no. See #248

Does not sure what I have to do. I have following the codes that you share, Now I've change surface input to the surface view. But I don't know where should I calling mPrevCb.onGetYuvFrame(data);

[begeekmyfriend]

Use MediaProjection for screen recording which yasea does not support currently

Okay, I see

The image I got from this has black frames around it. Here's a StackOverflow question I wrote about it:
