When re-encoding ffmpeg will automatically rotate the video. This takes a set of parameters to control the direction of the transpose/flip/rotate operation and to prevent the transpose from taking place. ffmpeg -i inputVideo.mp4 -vf "transpose=dir=1" rotatedVideo.mp4 You are using the transpose filter using -vf in FFmpeg. Here is the command line for rotating a video using FFmpeg’s transpose filter. Rotate videos 90 or 180 degrees using ffmpeg. ffmpeg -i in.mp4 -vf "rotate=-PI/2" out.mp4 The transpose filter will work equally well for 90 degrees, but for other angles this is a faster or only choice. With 90 degrees equating with PI/2, you can do it like so: ffmpeg -i in.mp4 -vf "rotate=PI/2" out.mp4 for counter-clockwise the angle must be negative. Ffmpeg flip video 90 degreesįfmpeg.exe -i parkjoy.mp4 -vf "transpose=dir=2:passthrough=landscape" parkjoy-90-flip.mp4 The above commandline says that FFmpeg should transpose the video 90 degrees CounterClockwise ONLY if the video is NOT landscape mode. BTW: If you have a pin2k cabinet the above method is the same, but instead of running the rotate180.zip you use this one to flip Y access on dmd videos. ffmpeg -f v4l2 -video_size 640x480 -i /dev/video0 -vcodec libx264 -f mpegts input.mp4 Of-course that if you need to process an already existing video, than this method is not the solution you are looking for.īut if you look at batch, you can very easily change it to *.flv or *.mov (other video filetypes) and re-run batch. Rotate and fix upside down or sideways cell phone videos quickly using FFMPEG - Duration: 3:46.Īnd then you can call your video device to capture a new video (see example below), and the video will be rotated/flipped. This video will show you how to rotate a video 180° using FFMPEG. Rotate 90 degrees clockwise: ffmpeg -i INPUT -vf transpose=1 -c:a copy OUTPUT 4.
Flip video horizontally: ffmpeg -i INPUT -vf hflip -c:a copy OUTPUT 3. Flip video vertically: ffmpeg -i INPUT -vf vflip -c:a copy OUTPUT 2. So, at the end I've managed to write a script which can be incorporated into the context menu of file managers like Dolphin, Nautilus, Thunar, etc.1. It seems ffmpeg is also taking into account the original file's EXIF metadata "Rotation: 90" and autorotating before the re-encoding process.
