android - Camera2api如何解决？E/BufferQueueProducer: dequeueBuffer: 试图超过最大出队缓冲区计数 (4)

问题描述

我正在使用
带有 sdk 28的 Samsung-A10

我正在尝试使用 camera2api 拍摄图像，但总是在收集 14 帧后我得到

I/com.oculid.daq: NativeAlloc concurrent copying GC freed 3481(447KB) AllocSpace objects, 33(1580KB) LOS objects, 49% free, 3MB/7MB, paused 149us total 174.997ms

D/IR_CAMERA: camera stateCallback onError
E/BufferQueueProducer: [ImageReader-1280x720f100m1-965-0] dequeueBuffer: attempting to exceed the max dequeued buffer count (4)

我可以在某些手机型号中看到这种行为，我正在尝试了解此错误的含义以及如何解决它，我会为任何线索感到高兴。

我在这里附上我的 OnimageAvailable 以防万一

    private ImageReader.OnImageAvailableListener readerListener = new ImageReader.OnImageAvailableListener() {
        @RequiresApi(api = Build.VERSION_CODES.P)
        @Override
        /*
         * gets a  the "reader" the callback is associated with.
         * transfer to bytes
         */

        public void onImageAvailable(ImageReader reader) {
            //Log.i(TAG,"readerListener on onImageAvailable");
            long imageReaderTime = SystemClock.elapsedRealtimeNanos();
            frameIndexForFileName++;
            //Log.i(TAG, String.format("Frame index: %08d", frameIndexForFileName));
            try (Image image = reader.acquireNextImage()) {

                //convert the image to bytes
                ByteBuffer buffer = image.getPlanes()[0].getBuffer();
                byte[] bytes = new byte[buffer.capacity()];
                buffer.get(bytes);

                double frameCaptureDuration = (double) (SystemClock.elapsedRealtimeNanos() - imageReaderTime) / 1000000;
                Log.i(TAG, String.format("TIME_MEASUREMENT: Capture of frame %08d took %f ms", frameIndexForFileName, frameCaptureDuration));

                Bitmap bmp = BitmapFactory.decodeByteArray(bytes,0,bytes.length);
                ByteArrayOutputStream stream = new ByteArrayOutputStream();
                bmp.compress(Bitmap.CompressFormat.JPEG, 60, stream);
                byte[] compressImage = stream.toByteArray();
                bmp.recycle();
                //image.close();
                //reader.discardFreeBuffers();
                imageListener.onImage(compressImage, imageReaderTime);



            } catch (Exception e) {
                e.printStackTrace();
                Log.e(TAG, "!!!!!!!!!!!!!!!!onImageAvailable: " + e );
            }
        }
    };

谢谢
