转换android.media.Image（YUV_420_888）为位图 [英] Convert android.media.Image (YUV_420_888) to Bitmap

问题描述

我试图用摄像机2 API来实现摄像头preVIEW图像数据处理如下建议：<一href="http://stackoverflow.com/questions/25462277/camera-$p$pview-image-data-processing-with-android-l-and-camera2-api">Camera preVIEW图像数据处理与Android L和摄像机2 API 。

I'm trying to implement camera preview image data processing using camera2 api as proposed here: Camera preview image data processing with Android L and Camera2 API.

我成功地接收使用onImageAvailableListener回调，但对于未来的处理我需要从YUV_420_888 android.media.Image得到位图。我搜索了类似的问题，但没有人帮助。

I successfully receive callbacks using onImageAvailableListener, but for future processing I need to obtain bitmap from YUV_420_888 android.media.Image. I searched for similar questions, but none of them helped.

能否请你建议我如何转换android.media.Image（YUV_420_888）为位图或者有听力为preVIEW帧更好的办法？

Could you please suggest me how to convert android.media.Image (YUV_420_888) to Bitmap or maybe there's a better way of listening for preview frames?

推荐答案

我写了一些code关于这一点，它的YUV DATAS preVIEW和昌它为JPEG DATAS，我可以用它来保存为位图，byte []的，还是其他人。（你可以看到类分配）。

和SDK文件说：
对于高效的YUV处理与android.renderscript：创建一个RenderScript分配具有受支持的YUV类型，IO_INPUT标志，和由getOutputSizes（Allocation.class）返回的尺寸之一，然后获得表面采用getSurface（）。

这里是code，希望它会帮助你：的https://github.com/pinguo-yuyidong/Camera2/blob/master/camera2/src/main/rs/yuv2rgb.rs

I write some code about this, and it's the YUV datas preview and chang it to JPEG datas ,and I can use it to save as bitmap ,byte[] ,or others.(You can see the class "Allocation" ).

And SDK document says:
"For efficient YUV processing with android.renderscript: Create a RenderScript Allocation with a supported YUV type, the IO_INPUT flag, and one of the sizes returned by getOutputSizes(Allocation.class), Then obtain the Surface with getSurface()."

here is the code, hope it will help you:https://github.com/pinguo-yuyidong/Camera2/blob/master/camera2/src/main/rs/yuv2rgb.rs
