Android 错误=来自qubuf的无效参数它是什么意思

我在想什么

Error = Invalid argument from qbuf

意味着

当我按下视频播放器上的home（主页）按钮时会发生这种情况。 这是新事物还是其他人以前见过这样的东西

我在谷歌上找不到任何东西 尤其是标签v412_utils

这在Nexus S设备上显示

就像我说的，只有当我按下主页按钮时才会发生这种情况。屏幕关闭和打开以及其他情况下的工作。只要按“主页”按钮就可以了。

我想我找到了答案。

这是因为在进行其他活动时，我不会暂停媒体或删除表面视图。我认为它在简历上失败了。我允许它暂停媒体并将可见性设置为“超出pm is屏幕”，它停止给我那个错误

我在不同的上下文中遇到了相同的错误，我还找不到解决方案，只是请注意它不是412，而是v4l2，4L2这是什么上下文。但我注意到，当我得到qbuff错误时，这是因为我正在使用pushbuffers对surfaceview执行某些操作，而不是销毁它。销毁时的surface view从未被调用，因此它的缓冲区存在问题。至少这是我发现的。就我而言，这是因为我试图将SurfaceView缩小到2x2像素。。低级库无法正确绘制相机预览。。但你是对的，这和SurfaceView有关。。
