无法从CipherInputStream加载图像

Question

Glide版本：4.8.0

集成库：无

设备/ Android版本：OnePlus 3，Android 9.0

问题详细信息/复制步骤/用例背景：我正在使用Glide从本地存储加载加密的图像。我已经使用AES-128加密了图像。我的第一种方法是解码图像，并使用生成的ByteArray通过Glide加载图像。这对于小图像效果很好，但是当我尝试加载视频缩略图时，对于大图像却出现了OOM错误。显然，这种方法是一种非常幼稚的方法。然后，我创建了一个自定义ModelLoader，以使用流加载图像，但它们并未加载。似乎问题出在解码路径上。 我是Glide的新手，所以将为您提供一些帮助。

//one line loader
 GlideApp.with(mContext)
                .load(CipherInputStream(FileInputStream(File(mPaths.get(p1).mPath)), decCypher))
                .thumbnail(0.05f)
                .override(size,size)
                .transition(DrawableTransitionOptions.withCrossFade())
                .apply(RequestOptions().placeholder(R.drawable.image_placeholder).dontTransform())
                .diskCacheStrategy(DiskCacheStrategy.NONE)
                .into(p0.imageView)


//custom ModelLoad
class EncryptedModelLoader : ModelLoader<CipherInputStream, CipherInputStream> {
    override fun buildLoadData(model: CipherInputStream, p1: Int, p2: Int, p3: Options): ModelLoader.LoadData<CipherInputStream>? {
        return ModelLoader.LoadData(ObjectKey(model.toString()), EncryptedDataFetcher(model))
    }

    override fun handles(p0: CipherInputStream): Boolean {
        return true
    }
}

//custom DataFetcher
class EncryptedDataFetcher : DataFetcher<CipherInputStream> {

    private var mModel : CipherInputStream

    constructor(model : CipherInputStream){
        mModel = model
    }


    override fun loadData(priority: Priority, callback: DataFetcher.DataCallback<in CipherInputStream>) {
        var buffer = ByteArray(1024)

        callback.onDataReady(mModel)

    }


    override fun getDataClass(): Class<CipherInputStream> {
        return CipherInputStream::class.java
    }

    override fun cleanup() {
        mModel.close()
    }

    override fun getDataSource(): DataSource {
        return DataSource.LOCAL
    }

    override fun cancel() {
    }
}


//custom ModelLoaderFactory
class EncryptedModelLoaderFactory  : ModelLoaderFactory<CipherInputStream, CipherInputStream> {
    override fun build(p0: MultiModelLoaderFactory): ModelLoader<CipherInputStream, CipherInputStream> {
        return EncryptedModelLoader()
    }

    override fun teardown() {
    }
}

//GlideAppModule
@GlideModule
class MAGM : AppGlideModule(){


    override fun registerComponents(context: Context, glide: Glide, registry: Registry) {
        super.registerComponents(context, glide, registry)
        registry.prepend(CipherInputStream::class.java, CipherInputStream::class.java, EncryptedModelLoaderFactory())
    }
}
