命令行ffmpeg批量旋转视频

ffmpeg批量旋转视频

 

//转化较快，逆时针旋转的度数

ffmpeg -i test.mp4 -c copy -metadata:s:v:0 rotate=180 rotate180.mp4

 

//转化用时较长

ffmpeg -i test.mp4 -vf "transpose=2,transpose=2" -codec:a copy rotate-180.mp4

 

注释：

rem For the transpose parameter you can pass:

rem 0 = 90CounterCLockwise and Vertical Flip (default)

rem 1 = 90Clockwise

rem 2 = 90CounterClockwise

rem 3 = 90Clockwise and Vertical Flip

 

rem To rotate 180 degrees, instead use "transpose=2,transpose=2"

rem Using -codec:a copy will simply copy the audio instead of reencoding it.
