1、setBufferCount failure
native_window_set_buffer_count调用失败，该mNativeWindow已无法使用，确认是否已被销毁
E/BufferQueue( 2188): [SurfaceView] setBufferCount: BufferQueue has been abandoned!
E/Surface (11666): IGraphicBufferProducer::setBufferCount(10) returned No such device

native_window_set_buffer_count调用失败，该mNativeWindow包含一些DEQUEUED Buffer，需确保所有Buffer是QUEUED或Canceld
E/BufferQueue( 2174): [SurfaceView] setBufferCount: client owns some buffers
E/Surface (17172): IGraphicBufferProducer::setBufferCount(10) returned Invalid argument

E/BufferQueue(2170): [SurfaceView] setBufferCount: client owns some buffers
E/Surface(3176): IGraphicBufferProducer::setBufferCount(10) returned Invalid argument

2、queueBuffer failure
queueBuffer调用失败，需确认该Buffer当前的状态，state=2 即QUEUED
E/BufferQueue( 2174): [SurfaceView] queueBuffer: slot 4 is not owned by the client (state=2)
E/Surface (17172): queueBuffer: error queuing buffer to SurfaceTexture, -22

queueBuffer调用失败，需确认该Buffer当前的状态，state=3 即ACQUIRED
E/BufferQueue(2190): [SurfaceView] queueBuffer: slot 0 is not owned by the client (state=3)
E/Surface(7246): queueBuffer: error queuing buffer to SurfaceTexture, -22

3、dequeueBuffer failure
native_window_dequeue_buffer_and_wait调用失败，需提前配置Surface,配置方式native_window_set_buffer_count
E/BufferQueue( 2444): [ScreenshotClient] dequeueBuffer: can't dequeue multiple buffers without setting the buffer count

4、cancelBuffer failure
02-01 08:11:52.635: E/Surface(3176): getSlotFromBufferLocked: unknown buffer: 0x63a4f9e0

相关概念
Producer 生产者应用程序客户端
Consumer 消费者 BufferQueue 服务端

State	Value	Description
BufferSlot::FREE	0	Buffer当前可用，也就是说可以被dequeued。此时Buffer的owner可认为是BufferQueue
BufferSlot::DEQUEUED	1	Buffer已经被dequeued，还未被queued或canceld。此时Buffer的owner可认为是producer(应用程序)，这意味着server端(BufferQueue)不可以对这块缓冲区进行操作
BufferSlot::QUEUED	2	Buffer已经被客户端queued，除特别情况外此时还不能对它进行dequeue，而可以acquired。此时的owner是BufferQueue
BufferSlot::ACQUIRED	3	Buffer的owner改为consumer，可以released，然后状态又返回FREE

过程：FREE->DEQUEUED->QUEUED->ACQUIRED->FREE
