I just wanted to use my bash script written in Debian 8 in
cygwin(latest, win10
64bit), but does not work.
At a specific line there is a command substitution trying to get
result from
ffprobe:
VHEIGHT=$(ffprobe -v error -show_entries stream=width,height -of
default=noprint_wrappers=1 ${OLDFILE} | grep "height" | cut -f2 -d'=')
For debugging purpose the same command is executed without putting the
result
into a variable, and works! Does anyone know why is it not working in
cygwin?
Code:
...
declare -i VHEIGHT
ffprobe -v error -show_entries stream=width,height -of
default=noprint_wrappers=1 ${OLDFILE} | grep height | cut -f2 -d'='
VHEIGHT=$(ffprobe -v error -show_entries stream=width,height -of
default=noprint_wrappers=1 ${OLDFILE} | grep "height" | cut -f2 -d'=')
...
Here is some debug log (set -x):
....
+ declare -i VHEIGHT
+ ffprobe -v error -show_entries stream=width,height -of
default=noprint_wrappers=1 P1220312.MP4
+ grep height
+ cut -f2 -d=
2160 # this woudl be the desired value
+ VHEIGHT= # here the variable is empty!
+ VIDSTABDETECTOPTS=:shakiness=10
+ VIDSTABDETECTOPTS+=:result=P1220312-stab.trf
+ VIDSTABTRANSFORMOPTS+=:crop=keep
....
The same in Linux bash:
...
+ declare -i VHEIGHT
+ ffprobe -v error -show_entries stream=width,height -of
default=noprint_wrappers=1 P1220312.MP4
+ grep height
+ cut -f2 -d=
2160
++ ffprobe -v error -show_entries stream=width,height -of
default=noprint_wrappers=1 P1220312.MP4
++ grep height
++ cut -f2 -d=
+ VHEIGHT=2160 # here is the desired value in the variable!!!
...
Any suggestions?
