As @Volodya mentioned: this is not possible without re-encoding, unless the movie container supports it or you are using MJPEG codec. Also see: http://video.stackexchange.com/a/15021/6685 Based on this answer you can use ffmpeg with transpose argument to rotate a video: ffmpeg -i input -vf transpose=2 output 0 = 90 CounterCLockwise and Vertical Flip ...
