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?
视频：MKV, OGM, AVI, DivX, WMV, QuickTime, Real, MPEG-1, MPEG-2, MPEG-4, DVD (VOB)... (编码器：DivX, XviD, MSMPEG4, ASP, H.264, AVC...) 音频：OGG, MP3, WAV, RA, AC3, DTS, AAC, M4A, AU, AIFF... 字幕：SRT, SSA, ASS, SAMI...
