/**
|
|
* Generic buffer for fast recycling for media/stagefright.
|
|
*
|
|
* During media pipeline buffer references are created, shared and
|
|
* destroyed frequently. The underlying buffers are allocated on demand
|
|
* by a buffer pool, and are recycled to the buffer pool when they are
|
|
* no longer referenced by the clients.
|
|
*
|
|
* Initially all buffers in media HAL should be NativeHandle(actually native_handle_t).
|
|
* HardwareBuffer(actually AHardwareBuffer) for GraphicBuffer is added from V2.
|
|
*
|
|
* E.g. ion or gralloc buffer
