Buffers and Events

The data flowing through a pipeline consists of a combination of buffers and events. Buffers contain the
actual media data. Events contain control information, such as seeking information and end-of-stream
notifiers. All this will flow through the pipeline automatically when it’s running. This chapter is mostly
meant to explain the concept to you; you don’t need to do anything for this

这一章旨在向你解释buffer和event的概念，它们一般会由流水线自动处理，你不需要过多考虑。

缓冲区包含数据，而事件包含信息。
