做视频采集与处理，自然少不了要学会分析YUV数据。因为从采集的角度来说，一般的视频采集芯片输出的码流一般都是YUV数据流的形式，而从视频处理（例如H.264、MPEG视频编解码）的角度来说，也是在原始YUV码流进行编码和解析，所以，了解如何分析YUV数据流对于做视频领域的人而言，至关重要。本文就是根据我的学习和了解，简单地介绍如何分析YUV数据流。-Do video capture and processing, natural and ultimately, to learn to analyze YUV data. From the acquisition point of view, the video capture chip output stream are generally in the form of YUV data stream (such as H.264, MPEG video codec) point of view, but also in the original YUV video processing stream encoding and parsing, YUV data stream for people to do the video field, it is essential to understand how to analyze. This article is based on my study and understanding, a brief introduction to how to analyze YUV data stream.
