JNI MattoBitmap 异常

Question

我已经实现了camerax并通过将其成功转换为位图而将“图像代理”输出转为jni函数，并且我有2个从opencv github获得的函数，它们将位图转换为mat然后mat转换为位图

这些是jni中的函数

1-BitmapToMat（我猜效果很好）

void bitmapToMat(JNIEnv * env, jobject bitmap,  Mat& dst , jboolean needUnPremultiplyAlpha){
    AndroidBitmapInfo  info;
    void*              pixels = 0;

    try {
        CV_Assert( AndroidBitmap_getInfo(env, bitmap, &info) >= 0 );
        CV_Assert( info.format == ANDROID_BITMAP_FORMAT_RGBA_8888 ||
                   info.format == ANDROID_BITMAP_FORMAT_RGB_565 );
        CV_Assert( AndroidBitmap_lockPixels(env, bitmap, &pixels) >= 0 );
        CV_Assert( pixels );
        dst.create(info.height, info.width, CV_8UC4);
        if( info.format == ANDROID_BITMAP_FORMAT_RGBA_8888 )
        {
            Mat tmp(info.height, info.width, CV_8UC4, pixels);
            if(needUnPremultiplyAlpha) cvtColor(tmp, dst, COLOR_mRGBA2RGBA);
            else tmp.copyTo(dst);
        } else {
            // info.format == ANDROID_BITMAP_FORMAT_RGB_565
            Mat tmp(info.height, info.width, CV_8UC2, pixels);
            cvtColor(tmp, dst, COLOR_BGR5652RGBA);
        }
        AndroidBitmap_unlockPixels(env, bitmap);
        return;
    } catch(const cv::Exception& e) {
        AndroidBitmap_unlockPixels(env, bitmap);
        jclass je = env->FindClass("java/lang/Exception");
        env->ThrowNew(je, e.what());
        return;
    } catch (...) {
        AndroidBitmap_unlockPixels(env, bitmap);
        jclass je = env->FindClass("java/lang/Exception");
        env->ThrowNew(je, "Unknown exception in JNI code {nBitmapToMat}");
        return;
    }
}

2- Mat to Bitmap（我用这个函数出错）

void MattoBitmap(JNIEnv * env,Mat src , jobject bitmap, jboolean needPremultiplyAlpha)
{
    AndroidBitmapInfo  info;
    void*              pixels = 0;

    try {
        CV_Assert( AndroidBitmap_getInfo(env, bitmap, &info) >= 0 );  **//basically it gives me error in this line**
        CV_Assert( info.format == ANDROID_BITMAP_FORMAT_RGBA_8888 ||
                   info.format == ANDROID_BITMAP_FORMAT_RGB_565 );
        CV_Assert( src.dims == 2 && info.height == (uint32_t)src.rows && info.width == (uint32_t)src.cols );
        CV_Assert( src.type() == CV_8UC1 || src.type() == CV_8UC3 || src.type() == CV_8UC4 );
        CV_Assert( AndroidBitmap_lockPixels(env, bitmap, &pixels) >= 0 );
        CV_Assert( pixels );
        if( info.format == ANDROID_BITMAP_FORMAT_RGBA_8888 )
        {
            Mat tmp(info.height, info.width, CV_8UC4, pixels);
            if(src.type() == CV_8UC1)
            {
                cvtColor(src, tmp, COLOR_GRAY2RGBA);
            } else if(src.type() == CV_8UC3){
                cvtColor(src, tmp, COLOR_RGB2RGBA);
            } else if(src.type() == CV_8UC4){
                if(needPremultiplyAlpha) cvtColor(src, tmp, COLOR_RGBA2mRGBA);
                else src.copyTo(tmp);
            }
        } else {
            // info.format == ANDROID_BITMAP_FORMAT_RGB_565
            Mat tmp(info.height, info.width, CV_8UC2, pixels);
            if(src.type() == CV_8UC1)
            {
                cvtColor(src, tmp, COLOR_GRAY2BGR565);
            } else if(src.type() == CV_8UC3){
                cvtColor(src, tmp, COLOR_RGB2BGR565);
            } else if(src.type() == CV_8UC4){
                cvtColor(src, tmp, COLOR_RGBA2BGR565);
            }
        }
        AndroidBitmap_unlockPixels(env, bitmap);
        return;
    } catch(const cv::Exception& e) {
        AndroidBitmap_unlockPixels(env, bitmap);
        jclass je = env->FindClass("java/lang/Exception");
        env->ThrowNew(je, e.what());
        return;
    } catch (...) {
        AndroidBitmap_unlockPixels(env, bitmap);
        jclass je = env->FindClass("java/lang/Exception");
        env->ThrowNew(je, "Unknown exception in JNI code {nMatToBitmap}");
        return;
    }
}

我尝试了很多东西，但仍然不知道问题是什么？有人可以帮我解决这个问题吗？
