renderscript

问题 I use RenderScript in my app to do several image processing tasks. Sometimes, I randomly get the following exception: 10-10 15:27:04.479: E/AndroidRuntime(2113): FATAL EXCEPTION: FinalizerWatchdogDaemon 10-10 15:27:04.479: E/AndroidRuntime(2113): java.util.concurrent.TimeoutException: android.renderscript.Type.finalize() timed out after 10 seconds 10-10 15:27:04.479: E/AndroidRuntime(2113): at android.renderscript.RenderScript.nObjDestroy(RenderScript.java:216) 10-10 15:27:04.479: E

问题 I have a Renderscript which processes an image that is given in output to an Allocation. I want to use this Allocation as a texture in my OpenGL program but I don't know how to get a texture ID from the Allocation. On the other hand, I know I could use a graphic Renderscript, but since it has been deprecated, I guess there must be some other way to achieve the same result. 回答1: Specify USAGE_IO_OUTPUT when you create the Allocation. Assuming you are generating the texture data in a script you

问题 I am trying to understand Renderscript. Could somebody have a look at this code, and let me know what the in parameter is ? It is not an Allocation object, so it is an Element? Why is it an array then? (I got the code from here, and modified it, http://www.jayway.com/2014/02/11/renderscript-on-android-basics/) #pragma version(1) #pragma rs java_package_name(foo.bar) rs_allocation inPixels; int height; int width; void root(const uchar4 *in, uchar4 *out, uint32_t x, uint32_t y) { float3 pixel =

问题 I am researching RenderScript in an university project. We wanted to find the scheduler that selects where the RenderScript code will run (on the CPU? The GPU? A DSP?) and study how it makes this choice. The problem is, we couldn't find the source code of anything related to a scheduler. In fact, we couldn't find a single reference to the term "GPU" in the source code. This is what we found about RenderScript in the Android source: The RenderScript runtime: https://android.googlesource.com

问题 I am trying to include the Renderscript support library into my project. I am getting the following error. android.support.v8.renderscript.RSRuntimeException: Error loading RS jni library: java.lang.UnsatisfiedLinkError: Couldn't load rsjni: findLibrary returned null I am not using any Renderscript jar files, I am attempting to use it via Gradle. Here are my Gradle.build files TOP LEVEL buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:1.2.3' }

问题 I am new to renderscript. I am trying to add two array elements using renderscript. I am able to pass the value to renderscript from Android by invoke_add method for coming back to Android framework from renderscript I was suggested to use rsSendToclient() . How can I use rsSendToClient or any other way for coming back to android framework. 回答1: You have to use rsSendToClient(1, &data, sizeof(data)); in your script and decode the data in Java like this: RSMessageHandler l_resHandler = new

问题 i just want to use RenderScript's ScriptIntrinsicBlur in my application , i've added renderscript.v8.jar (in android support lib v8) for supporting under 17 apis but it crashes on this line (in api <17 this happens it works fine on 4.2 or higher) : RenderScript rs = RenderScript.create(getApplicationContext()); and the Exception output is java.lang.RuntimeException: An error occured while executing doInBackground() at android.os.AsyncTask$3.done(AsyncTask.java:299) at java.util.concurrent

问题 I am new to Android Renderscript. I need to write a convolution multiplication in RenderScript since the final application is going to run on Android. Data stream is going to be an image. More specifically, I am not able to write the core logic using forEach functionality, though I can do it in Java, but speed it too slow! Please help! Steve 回答1: During the rsForEach call (or other Renderscript function), you can access the neighbouring pixels of the original image (or whatever type of data

问题 For plattform independence (desktop, cloud, mobile, ...) it would be great to use OpenCL for GPGPU development when speed does matter. I know Google pushes RenderScript as an alternative, but it seems to be only be available for Android and is unlikely to be ever included in iOS. Therefore I seek for a solution to execute OpenCL code within Android Apps. 回答1: The only Android devices I know that support OpenCL are the ones based on the Mali T600 family of chips (article here). They have an

I've been wondering if it was possible to use OpenCL for Android, find out that it wasn't possible, and dropped the subject altogether
