Avconv - Generate portrait image from portrait video

I am trying to generate an image from a video file using avconv function. Everything works fine except of the portrait video files. The generated image is in landscape or let's say it is turn to -90°.

avconv.exe -i video.MOV -r 01 -ss 00:00:05 -t 00:00:01 -f image2 preview-image.jpg

Is there any solution to generate a vertical/portrait image?

I tried to check the video information to figure out if there is a difference between portrait videos and landscape videos, but the dimensions are always as landscape on both video types.

avconv.exe -i video.MOV

avconv version 10.6, Copyright (c) 2000-2014 the Libav developers

Any suggestions are welcome. Thanks in advance.

Assuming the Libav devs haven't changed anything significant from ffmpeg, you should run

avconv.exe -i video.MOV -vf transpose=cclock -ss 00:00:05 preview-image.jpg

Recent versions of ffmpeg will autorotate the video, based on metadata.
