using ffmpeg on both landscape and portait pics

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I'm using the following command:

ffmpeg -i port001.jpg -vf "scale=100:-1" /tmp/1/port_converted_100-1.jpg

It is working fine on landscape pics but it automatically rotate the portrait pics.
Any idea how to avoid the rotation?

The exif Orientation tag is ignored by `ffmpeg`

This is ticket #6945: ffmpeg fails at jpeg EXIF orientation.

Rotate your images before using `ffmpeg`*

Manually

jpegtran can be used to losslessly rotate images. You can use it manually to rotate or create a script to rotate based on the Orientation tag.

jpegtran -rotate 90 input.jpg > output.jpg

Note that this will strip some of the exif data. If you want to keep it all add -copy all then remove the now incorrect Orientation tag with exiftool:

exiftool -Orientation="" output.jpg

With `exifautotran`

This tool with automatically re-orient the images according to the Orientation tag:

mkdir images

cp *.jpg images

cd images

exifautotran *.jpg

_{* If ticket #6945 is fixed then this method will become moot.}

Viewing exif orientation tag in JPG image

You can use exiftool to view the orientation:

$ exiftool -Orientation -S image.jpg

  Orientation: Rotate 90 CW

$ exiftool -Orientation -n -S image.jpg

  Orientation: 6

Now you can scale with `ffmpeg`

ffmpeg -i input.jpg -vf "scale=100:-1" output

For more fancy scaling see Resizing images with ffmpeg to fit into specific sized box.

Is there any way to know the pic orientation? If there is not, this solution doesn't fit my needs as I don't know in advance what will be the pic orientation. I'm provising service to re-scale any pic no mater what is the orientation.

@Benny I added some examples of viewing the Orientation tag with exiftool. Or just use exifautotran as mentioned before and you won't have to worry about Orientation.
