ffprobe - Video - Rotate

To detect whether videos are recorded in portrait or landscape mode.

Video orientation detection

ffprobe -v error -select_streams v:0 -show_entries stream_tags=rotate -of csv=s=x:p=0 input.mp4

NOTE: On unrotated videos, the above command produces no output.

Getting Width, Height, Rotation

ffprobe -v error -select_streams v:0 -show_entries stream=width,height:stream_tags=rotate -of csv=p=0 input.mp4

returns:

1920,1080,270

NOTE: Even though the rotation here is 270, the width and height are still shown as if the orientation was portrait.

Due to the 270 rotation, in reality the actual input should be 1080×1920, and not 1920×1080.
- But ffprobe reports the actual width x height; Width is displayed first, then height (no matter the order it is requested).

Using Grep

ffprobe somevideo.mp4 2>&1 | grep rotate

returns:

rotate          : 90

In a Bash Script

rotate=$(ffprobe -v error -select_streams v:0 -show_entries stream_tags=rotate -of csv=s=x:p=0 "${sourceFile}")
if [ "$rotate" != "" ]; then 
    echo "We need to rotate: $rotate"
fi
