使用批處理腳本(BAT)編碼視頻非常方便，尤其當視頻序列非常多的時候，更是省了不少簡單重復性勞動。

只要學會批處理里面幾個基本的命令就行了，感覺和c/c++差不多。

set：設置變量(注意：變量一般情況下是字符串，而不是整形或者其他類型)

%變量名%：可以取到變量的值

傳上來一個做實驗的批處理腳本做示范(其中調用了ffmpeg和x264)：

@echo?off

@rem?使用此腳本生成實驗序列

@rem?設置序列名稱

set?xuliename=src08

@rem?幀率分辨率比特率參數

set?resolution1=1920x1080

set?resolution2=1280x720

set?resolution3=848x480

set?resolution4=640x360

set?resolution5=480x272

set?framerate1=25

set?framerate2=20

set?framerate3=15

set?framerate4=12.5

set?framerate5=10

set?framerate6=5

set?bitrate1=254

set?bitrate2=508

set?bitrate3=763

set?bitrate4=1017

set?bitrate5=1526

set?bitrate6=2035

set?bitrate7=2544

@rem?生成特定分辨率，然后再進行上變換
