檢測視頻編碼信息(MediaInfo)

檢測視頻編碼信息,MediaInfo 用來分析視頻和音頻文件的編碼和內(nèi)容信息。目前幾個主流的CODEC viewer的功能都給包進(jìn)來了.像是對新格式的支持, 提供相關(guān)CODECs和播放軟件的網(wǎng)頁連結(jié)等等, 我覺得該有的功能都有了。

MediaInfo的主要功能特點(diǎn)：

支持眾多視頻和音頻文件格式
多種查看方式：文本，表格，樹形圖，網(wǎng)頁……
自定義查看方式
信息導(dǎo)出：文本，CSV，HTML……
三種發(fā)布版本：圖形界面，命令行，DLL(動態(tài)鏈接庫)
與Windows資源管理器整合：拖放，右鍵菜單
國際化：有多種界面語言供選擇
(軟件界面)輕松實現(xiàn)本地化 (需要志愿者翻譯語言文件)


使用MediaInfo可以獲得多媒體文件的哪些信息?
內(nèi)容信息：標(biāo)題，作者，專輯名，音軌號，日期，總時間……
視頻：編碼器，長寬比，幀頻率，比特率……
音頻：編碼器，采樣率，聲道數(shù)，語言，比特率……
文本：語言和字幕
段落：段落數(shù)，列表

MediaInfo支持哪些文件格式?

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