Hi,
I am trying to write a script that records a window on my screen. No pb with that.
To go further I would like to choose an incremental fileName for output incrementing if the fileName already exist.
I have trouble doing it so before dealing with the incrementation itself, I want to check I can substitute the calculated name in the ffmpeg command.
I get this message
Code:
it works perfectly. My question is : "What is wrong ?"

Code:
filename="~/Bureau/essai"
index=1 #I[B] will deal with the incrementation of index after this part works [/B]
mystring="${fileName}${index}.mkv" #omce I have a proper index I concatenate the name with index and name extension
echo ${mystring} # gives ~/Bureau/essai1.mkv seems to be what I expect
ffmpeg -f alsa ..... -y ${mystring} # gives error message ~/Bureau/essai1.mkv: No such file or directory despite -y to force overwriting
I get this message
However if I put the file name directly in the command like this~/Bureau/essai1.mkv No such file or directory despite -y to force overwriting
Code:
Code:
ffmpeg -f alsa ..... -y ~/Bureau/essai1.mkv
it works perfectly. My question is : "What is wrong ?"
