SurfaceTexture 已被废弃 [英] SurfaceTexture has been abandoned
本文介绍了SurfaceTexture 已被废弃的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我是这里的新手和 android :)我有一个 android 应用程序，它从相机接收帧并尝试处理它们(也使用 OpenCv 查找特定颜色).我使用 SurfaceTexture setPreviewCallbackWithBuffer() 然后使用画布显示它们.但是，在处理了一些帧后，我的相机冻结了，我收到:SurfaceTexture 已被放弃！请注意，在显示之前正在处理一些帧，有多少? - 每次都取决于..我的问题是:这是由缓冲区、内存泄漏还是其他原因引起的?
i am a newbie here and to android :) i have an android app that is receiving frames from camera and trying to process them(finding a specific color using also OpenCv). im using SurfaceTexture setPreviewCallbackWithBuffer() and then displaying them using canvas. But,after processing some frames,my camera freezes and i receive: SurfaceTexture has been abandoned! Note that is processing some frames before displaying this,how many?-depends each time.. My question is: is this caused by the buffers, memory leaks or something else?
任何帮助将不胜感激！这是我的 Logcat:

简短的回答:保留对 SurfaceTexture 的引用，以便对象不会被垃圾收集(从而被丢弃).
The short answer: Keep a reference to your SurfaceTexture so that the object doesn't get garbage collected (and thereby abandoned).
我遇到了同样的问题(在某些设备上).在对 AOSP 代码进行了一些挖掘之后，我了解到如果对象的所有强引用都消失了，那么放弃"对象的一种方法......
I was getting this same problem (on certain devices). After some digging through the AOSP code, I learned that one way for an object to be "abandoned" if for all of its strong references to go away...
void ConsumerBase::onLastStrongRef(const void* id) {
abandon();
}
所以我返回到我的代码并注意到我正在创建一个 SurfaceTexture，将它传递给 setPreviewTexture()，然后退出而不保留对 SurfaceTexture 的引用:
So I returned to my code and noticed that I was creating a SurfaceTexture, passing it to setPreviewTexture(), and then exiting without keeping a reference to the SurfaceTexture:
SurfaceTexture texture = new SurfaceTexture(10);
try {
mCamera.setPreviewTexture(texture);
} catch (IOException e) {
Log.d(Tag, "Failed to setPreviewTexture");
return 0;
}
我做了一个简单的更改，使 SurfaceTexture 成为我的类的成员对象，现在SurfaceTexture 已被放弃"错误消失了 - 我的预览继续通过 onPreviewFrame() 提供帧.
I made a simple change to make the SurfaceTexture a member object of my class, and now the "SurfaceTexture has been abandoned" error is gone - and my preview continues to deliver frames via onPreviewFrame().
这篇关于SurfaceTexture 已被废弃的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
