FIX rotation of movie
usage rotatefix movie001.mpg 90 (or -90)
If your data is in a external library, you can do this on the file in the library. After that you have to select it and do the following:
- Refresh encoded videos
- Refresh metadata
- Refresh thumbnails
#!/bin/bash
#set -x
if [ "$#" -lt 2 ]; then
echo >&2 'fix filename 90||-90||0'
exit 1
fi
fix=0
exiftool $1 | grep "^Create Date" | grep 0000 && fix=1
dater=$(realpath $1| grep -oE '[0-9]{8}' | head -1 )
if [ $2 == "90" ] ; then
ffmpeg -i $1 -vf 'transpose=1' -c:a copy tmp_${1}
mv tmp_${1} $1
fi
if [ $2 == "-90" ] ; then
ffmpeg -i $1 -vf 'transpose=2' -c:a copy tmp_${1}
mv tmp_${1} $1
fi
if [ $fix == "1" ] ; then
echo "Fixing date"
touch -t ${dater}1200.00 $1

FIX DATES FILES in /2006/20060701/ structure
This touches files which have no exif info, to the date of the directory to that date with time 12:00
