- I want to trim the part between 37:23 and 37:33 of the output video
- Is there a way I can do this without writing a separate ffmpeg command like a pipe or a chain or multiple filter_complex expressions ?

Use ffmpeg to extract picture from m4v file
31 octobre 2017, par BrianI used a program called MetaZ on my mac to tag all my video files (m4v). I am now trying to use these m4v files in Kodi which requires .nfo files and separate picture files for movie posters, etc. I want to extract the picture that is already in the m4v file.
When I use ffprobe -show_streams, I can see that index4 is a png file (codec_name=png). How do I extract it ? I believe ffmpeg can do it, but can’t figure out how.
Here is the output from ffprobe :

bash - forcing globstar asterisk expansion when passed to loop
1er juillet 2020, par Kittywhiskers Van GoghI am attempting to write a script that finds the extension of all files within a directory and normalise them using
ffmpegto conform to a singular file format, codec and resolution.

#!/usr/bin/env bash

# We need to use globstar because we want to run this recursively (bash >4.0)
# This script won't run on macOS unless you install bash from homebrew
shopt -s globstar nullglob

# macOS doesn't have some stuff that we need, presuming you have homebrew already
# then run "brew install ffmpeg rename"
if ! [ -x "$(command -v ffmpeg)" ] || ! [ -x "$(command -v rename)" ]; then
 echo 'Required applications are absent, quitting :(' >&2
 exit 1
fi

# We need to know what file extensions we are dealing with
DISCOVERED_EXTENSIONS=$(find . -type f -name '*.*' | sed 's|.*\.||' | sort -u | tr '\n' ' ' | sed "s| | ./\**/*.|g" | rev | cut -c9- | rev | echo "./**/*.$(stdin)")

# Let's ignore newlines for now
IFS=$'\n'; set -f

# Within the loop
for f in $(echo $DISCOVERED_EXTENSIONS | tr ' ' '\n'); do
# Do nothing if there are no files to begin with
# if [ -z ${f+x} ]; then
# echo "no files found, exiting";
# else
# First get rid of all period/full-stops except the extension to prevent confusion
# rename "s/\.(?=[^.]*\.)/_/g" "$f";
# Now run conversion and save files with prefix processed_
# ffmpeg -i "$f" -vf scale=-1:720 -crf 18 \
# -c:v libx264 -preset veryslow -c:a libvo_aacenc -b:a 128k -c:s copy \
# "processed_${f%.*}.mp4";
# fi
 ls $f;
done

# No longer ignore newlines
unset IFS; set +f

# Stop using recursiveness after we're done
shopt -u globstar nullglob


I have commented out all the actual conversion code in an attempt to debug it, running this script alone, I get :


ls: ./**/*.avi: No such file or directory
ls: ./**/*.jpg: No such file or directory
ls: ./**/*.mkv: No such file or directory
ls: ./**/*.mp4: No such file or directory


It is passing
ls "./**/*.avi"instead ofls ./**/*.avi(because of no variable expansion). I attempted to use eval, envsubst and even used a customexpandfunction, to no avail

The result of
echo "$DISCOVERED_EXTENSIONS"is :

./**/*.avi ./**/*.jpg ./**/*.mkv ./**/*.mp4


ShellCheck objected to my lack of quotation marks but adding them in did not do anything. What changes can be recommended so that value of
$fis the result of glob expansion and not the expression itself ?
