MATLAB读取AVI视频：Unable to locate decompressor to decompress video stream_avisource couldn't located a decompressor-优快云博客

本文介绍了在MATLAB中遇到无法解码AVI视频流的问题，分析了可能的原因是MATLAB不支持该视频格式。提出了两种解决方案：一是下载对应解码器解码后读取；二是使用视频转换软件将AVI文件转换为MATLAB支持的格式，如使用winAVI 9.0转换为RGB24编码的文件。

今天用MATLAB读取AVI视频，报错：Unable to locate decompressor to decompress video stream

MATLAB aviread命令支持的帧类型是灰度级是8位(索引式或灰度)、16位或是24位(即真彩色)的，应该是所读AVI文件格式不符合的关系。

上网查了一下，解决方案有2个：

1，下载相应的解码器，对AVI文件进行解码，再读取；
