尝试改下这个方法：

public static Bitmap imageProxyToBitmap(ImageProxy imageProxy, int rotationDegrees) throws Exception {
        ImageProxy.PlaneProxy yPlane = imageProxy.getPlanes()[0];
        ImageProxy.PlaneProxy uPlane = imageProxy.getPlanes()[1];
        ImageProxy.PlaneProxy vPlane = imageProxy.getPlanes()[2];

        ByteBuffer yBuffer = yPlane.getBuffer();
        ByteBuffer uBuffer = uPlane.getBuffer();
        ByteBuffer vBuffer = vPlane.getBuffer();
        yBuffer.rewind();
        uBuffer.rewind();
        vBuffer.rewind();

        int ySize = yBuffer.remaining();
        int uSize = uBuffer.remaining();
        int vSize = vBuffer.remaining();
        byte[] nv21 = new byte[ySize + uSize + vSize];

        int position = 0;

        // Add the full y buffer to the array. If rowStride > 1, some padding may be skipped.
        for (int row = 0; row < imageProxy.getHeight(); row++) {
            yBuffer.get(nv21, position, imageProxy.getWidth());
            position += imageProxy.getWidth();
            yBuffer.position(Math.min(ySize, yBuffer.position() - imageProxy.getWidth() + yPlane.getRowStride()));
        }

        int chromaHeight = imageProxy.getHeight() / 2;
        int chromaWidth = imageProxy.getWidth() / 2;
        int vRowStride = vPlane.getRowStride();
        int uRowStride = uPlane.getRowStride();
        int vPixelStride = vPlane.getPixelStride();
        int uPixelStride = uPlane.getPixelStride();

        // Interleave the u and v frames, filling up the rest of the buffer. Use two line buffers to
        // perform faster bulk gets from the byte buffers.
        byte[] vLineBuffer = new byte[vRowStride];
        byte[] uLineBuffer = new byte[uRowStride];
        for (int row = 0; row < chromaHeight; row++) {
            vBuffer.get(vLineBuffer, 0, Math.min(vRowStride, vBuffer.remaining()));
            uBuffer.get(uLineBuffer, 0, Math.min(uRowStride, uBuffer.remaining()));
            int vLineBufferPosition = 0;
            int uLineBufferPosition = 0;
            for (int col = 0; col < chromaWidth; col++) {
                nv21[position++] = vLineBuffer[vLineBufferPosition];
                nv21[position++] = uLineBuffer[uLineBufferPosition];
                vLineBufferPosition += vPixelStride;
                uLineBufferPosition += uPixelStride;
            }
        }

        YuvImage yuvImage = new YuvImage(nv21, ImageFormat.NV21, imageProxy.getWidth(), imageProxy.getHeight(), null);
        ByteArrayOutputStream stream = new ByteArrayOutputStream(nv21.length);
        yuvImage.compressToJpeg(new Rect(0, 0, yuvImage.getWidth(), yuvImage.getHeight()), 90, stream);

        Bitmap bitmap = BitmapFactory.decodeByteArray(stream.toByteArray(), 0, stream.size());
        if(rotationDegrees != 0){
            Matrix matrix = new Matrix();
            matrix.postRotate(rotationDegrees);
            bitmap = Bitmap.createBitmap(bitmap,0,0,bitmap.getWidth(),bitmap.getHeight(), matrix, true);
        }

        return bitmap;
    }
