ffmpeg rotate and resize
23 août 2014, par user1321964I’m trying to resize a movie and to rotate it counter-clockwise using ffmpeg.
I can achieve one or the other ok individuallyffmpeg -i MVI_8189.MOV -vf "transpose=2" -ss 00:00:12 -t 00:00:05 rotate.MOV
OR
ffmpeg -i MVI_8189.MOV -s 720x406 -ss 00:00:12 -t 00:00:05 resize.MOV
but if I try to do both, either-
ffmpeg -i MVI_8189.MOV -s 720x406 -ss 00:00:12 -t 00:00:05 resize.MOV
ffmpeg -i resize.MOV -vf "transpose=2" toutp.MOV
OR
ffmpeg -i MVI_8189.MOV -vf "transpose=2" -ss 00:00:12 -t 00:00:05 rotate.MOV
ffmpeg -i rotate.MOV -s 406x720 toutp.MOV
the final movie does not play, only audio, no video ; neither previewing in Finder, nor in Quicktime. More seriously once I have attempted to play it, I can’t then play any other movie whatsoever (only audio) - quicktime won’t quit, constantly need to force-quit it. The only way to then restore seems to be reboot OS-X
This though does work -
ffmpeg -i MVI_8189.MOV -vf "transpose=2" -ss 00:00:12 -t 00:00:05 rotate.MOV
ffmpeg -i rotate.MOV -s 720x406 toutp.MOV
but doesn’t do what I want - it stretches the movie in the wrong direction
Any ideas ?
