检测视频编码信息(MediaInfo)

检测视频编码信息,MediaInfo 用来分析视频和音频文件的编码和内容信息。目前几个主流的CODEC viewer的功能都给包进来了.像是对新格式的支持, 提供相关CODECs和播放软件的网页连结等等, 我觉得该有的功能都有了。

MediaInfo的主要功能特点：

支持众多视频和音频文件格式多种查看方式：文本，表格，树形图，网页……自定义查看方式信息导出：文本，CSV，HTML……三种发布版本：图形界面，命令行，DLL(动态链接库)与Windows资源管理器整合：拖放，右键菜单国际化：有多种界面语言供选择(软件界面)轻松实现本地化 (需要志愿者翻译语言文件)使用MediaInfo可以获得多媒体文件的哪些信息?内容信息：标题，作者，专辑名，音轨号，日期，总时间……视频：编码器，长宽比，帧频率，比特率……音频：编码器，采样率，声道数，语言，比特率……文本：语言和字幕段落：段落数，列表

MediaInfo支持哪些文件格式?
