renderscript

When Jelly Bean 4.2 was announced a month ago, Filterscript was also announced. It appears to be a language that is a subscript of Renderscript with a different file extension. And that's about all I know about the language. I have read the two total paragraphs that exist about Filterscript on the entire Internet and created a small .fs file with pragma rs_fp_relaxed , but it does not get picked up by the ADT builders like a normal .rs file is in the same location. My ADT is the latest public version (21.0.0), which seems to be too low for Filterscript. tools.android.com appears to have 21.0.1

I found there's lacking good documentation in RenderScript, for what I know, forEach in RS is to execute the root() for each individual item in the allocation. I am trying to make a library for Renderscript that does Image processing, as a starting point, I reached this great answer . But the problem, is that the blur operation is on Each pixel and each pixel requires another loop (n with blur width) of calculation. Although running on multi-core, it is still a bit too slow. I am trying to modify it to allow (two-pass) box filter, but that requires working on a single row or column instead of

I'm looking to return an array of struct from my renderscript kernel. My problem is that although I can create an array of the struct in java using the generated code and pass this to my root method by getting the allocation of the array generated from this, I cant get the array back into java. The Renderscript documentation says to use the copyTo method to copy out of the allocation which ensures that the renderscript has finished operating on it. However this method only supports float, int, byte, bitmap. Even after waiting several seconds before accessing the array to ensure that the

I am using render script in support library in my gradle file. renderscriptTargetApi 22 renderscriptSupportModeEnabled true After I added these 2 lines, I am getting this error at com.android.dx.merge.DexMerger.readSortableTypes(DexMerger.java:596) at com.android.dx.merge.DexMerger.mergeDexes(DexMerger.java:171) UNEXPECTED TOP-LEVEL EXCEPTION:com.android.dex.DexException: Multiple dex files define Landroid/support/annotation/AnimRes; at com.android.dx.merge.DexMerger.getSortedTypes(DexMerger.java:554) at com.android.dx.merge.DexMerger.mergeClassDefs(DexMerger.java:535) at com.android.dx.merge

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$3.done(AsyncTask.java:299) at java.util.concurrent.FutureTask$Sync.innerSetException(FutureTask.java:273) at java.util.concurrent.FutureTask.setException

I'm using RenderScript and Allocation to obtain YUV_420_888 frames from the Android Camera2 API, but once I copy the byte[] from the Allocation I receive only the Y plane from the 3 planes which compose the frame, while the U and V planes values are set to 0 in the byte[]. I'm trying to mimic the onPreviewframe from the previos camera API in order to perform in app processing of the camera frames. My Allocation is created like: Type.Builder yuvTypeBuilderIn = new Type.Builder(rs, Element.YUV(rs)); yuvTypeBuilderIn.setX(dimensions.getWidth()); yuvTypeBuilderIn.setY(dimensions.getHeight());
