How do you convert an entire directory with ffmpeg?
(34 answers)
Closed 1 year ago.
I used with script to add dynamic watermark to one video, how to adapt it to convert multiple videos?
ffmpeg -i test.mp4 -i logo.png -filter_complex "[1]colorchannelmixer=aa=0.6,scale=iw*0.7:-1[a];[0][a]overlay=x='if(lt(mod(t\,16)\,8)\,W-w-W*5/100\,W*5/100)':y='if(lt(mod(t+4\,16)\,8)\,H-h-H*2.5/100\,H*2.5/100)'" -c:v libx264 -an out.mp4
You just need to iterate the video files:
source_folder=$1
target_folder=$2
mkdir -p $target_folder
echo "procesing..."
for file in $source_folder/*.mp4 $source_folder/**/*.mp4 ; do
if [[ -f $file ]]; then
filename=$(basename -- "$file")
echo "source video:"$file "new :"$target_folder/$filename
ffmpeg -i "$file" -i logo.png -filter_complex "[1]colorchannelmixer=aa=0.6,scale=iw*0.7:-1[a];[0][a]overlay=x='if(lt(mod(t\,16)\,8)\,W-w-W*5/100\,W*5/100)':y='if(lt(mod(t+4\,16)\,8)\,H-h-H*2.5/100\,H*2.5/100)'" -c:v libx264 -an "$target_folder/$filename"
fi
done;
echo ""
echo "result: $target_folder"
find $target_folder | sort
Example:
bash script.sh /input /foo/bar/output

Want to convert my m4a files into mp3 files using a script. It would save some time... I have over 100 GB of music files.
OS: OSX10.14 / Terminal vs Bash script
I can run ffmpeg -v 5 -y -i musicFile.m4a -acodec libmp3lame -ac 2 -b:a 320k musicFile.mp3 from the terminal. It converts the file and I can see and play the file from itunes.
When I run the same from a bash script it fails to convert.
ffmpeg -v 5 -y -i $ENTRY_FILE -acodec libmp3lame -ac 2 -b:a 320k $MP3NAME
My ipod nano just died and I got a new mp3 player. Now I need to convert my itunes files from AAC format to MP3.
ffmpeg is an established video and music file converter.
When I run it from the bash script I tried a few things.
I added ./ in front of the file, that failed because it was installed under /usr/local/bin and not under the same directory.
I also tried sh ffmpeg... and that gave me the cannot execute a binary file.
#!/usr/bin/env bash
# convert m4a file to mp3
set -e
file_convert() {
ENTRY_FILE=$(printf %q "${entry}")
FILE_NAME=$(printf %q "$(basename "${entry}")")
DIR=$(printf %q "$(dirname "${entry}")")
NAME="${FILE_NAME%.*}"
EXT="${FILE_NAME##*.}"
MP3NAME="${DIR}/${NAME}.mp3"
printf "%*s%s\n" $((indent+2)) '' "$ENTRY_FILE"
printf "%*s\tNew File :\t%s\n" $((indent+2)) '' "$MP3NAME"
if [ $EXT == "m4a" ]
then
printf "%*s\tConverting: \t%s\n" $((index+2)) '' "$ENTRY_FILE"
ffmpeg -v 5 -y -i $ENTRY_FILE -acodec libmp3lame -ac 2 -b:a 320k $MP3NAME
fi
}
walk() {
local indent="${2:-0}"
printf "\n%*s%s\n\n" "$indent" '' "$1"
# If the entry is a file convert it
for entry in "$1"/*; do [[ -f "$entry" ]] && file_convert; done
# If the entry is a directory recurse
for entry in "$1"/*; do [[ -d "$entry" ]] && walk "$entry" $((indent+2)); done
}
# If the path is empty use the current, otherwise convert relative to absolute; Exec walk()
[[ -z "${1}" ]] && ABS_PATH="${PWD}" || pushd "${1}" && ABS_PATH="${PWD}"
walk "${ABS_PATH}"
popd
echo
I expect >./aacToMp3.sh ./music to traverses the music directory and convert each m4a file to .mp3.
It is walking the file system and printing out correct files, with the spaces escaped. When it hits the ffmpeg line it halts. I put the set -e at the top of the file to force it to fail if the command fails. Without the set -e it happily walks all the music files and prints them to the stdout.
If you have lots of files to process and a decent multi-core CPU and fast disk, I would recommend GNU Parallel which you can install with homebrew:
brew install parallel
Then make a copy of a few files in a test directory and try:
parallel --dry-run ffmpeg -v 5 -y -i {} -acodec libmp3lame -ac 2 -b:a 320k {.}.mp3 ::: *.m4a
If that looks good, replace --dry-run with --progress.
If that looks good, you can (make a backup first) and do the whole lot:
find path/to/music -name "*.m4a" -print0 | parallel -0 --progress ffmpeg -v 5 -y -i {} -acodec libmp3lame -ac 2 -b:a 320k {.}.mp3
Thanks for all the input.
After a while I ended up writing all the ffmpeg lines to a script file. Glad I did. I was able to quickly scan the file and see some errors and fix them.
This is what I came up with.
Basically I am writing straight text to stdout and directing it to a file. Which I converted to a shell script to convert each file. One at a time. Ran the generated script overnight.
file_convert() {
ENTRY_FILE=$(printf %q "${entry}")
FILE_NAME=$(printf %q "$(basename "${entry}")")
DIR=$(printf %q "$(dirname "${entry}")")
NAME="${FILE_NAME%.*}"
EXT="${FILE_NAME##*.}"
MP3NAME="${DIR}/${NAME}.mp3"
if [ $EXT == "m4a" ]
then
printf 'echo "Converting %s ..."\n' "$FILE_NAME"
printf 'ffmpeg -v 5 -y -i %s -acodec libmp3lame -ac 2 -b:a 320k %s\n\n' "$ENTRY_FILE" "$MP3NAME"
fi
}
The output looked like.
#!/usr/bin/env bash
echo "Converting 03\ It\'s\ Not\ My\ Time.m4a ..."
ffmpeg -v 5 -y -i /Users/arthuranderson/Documents/work/projects/mp3Convert/music/3\ Doors\ Down/3\ Doors\ Down\ \(Bonus\ Track\ Version\)/03\ It\'s\ Not\ My\ Time.m4a -acodec libmp3lame -ac 2 -b:a 320k /Users/arthuranderson/Documents/work/projects/mp3Convert/music/3\ Doors\ Down/3\ Doors\ Down\ \(Bonus\ Track\ Version\)/03\ It\'s\ Not\ My\ Time.mp3
echo "Converting 01\ Down.m4a ..."
ffmpeg -v 5 -y -i /Users/arthuranderson/Documents/work/projects/mp3Convert/music/311/Greatest\ Hits\ \'93-\'03/01\ Down.m4a -acodec libmp3lame -ac 2 -b:a 320k /Users/arthuranderson/Documents/work/projects/mp3Convert/music/311/Greatest\ Hits\ \'93-\'03/01\ Down.mp3
Mark I will try parallel when I purchase some more music next time.
Thanks everyone!
I'm a beginner.
I have a Bash script that embeds subtitles into mkv files if they exist in a directory.
for i in *.mkv; do
if [ -f "${i%mkv}"*"srt" ]; then
ffmpeg -i "$i" -f srt -i "${i%mkv}"*"srt" -map 0:0 -map 0:1 -map 1:0 -c:v copy -c:a copy -c:s srt $i.output.mkv
mv "${i%mkv}"*"srt" "${i%mkv}srt".old
mv $i $i.old
mv $i.output.mkv $i
else
echo $i "does not have srt file"
fi
done
It looks for all .mkv files that have an associated .srt file and does some ffmpeg magic to it. If it does not find an associated .srt file it says that the .mkv file "does not have srt file."
How can I make it so that at the conclusion of the for loop I get a print out of all the .mkv files that did have an .srt file and did successfully do all the other actions?
Thank you.
Let's use a Bash array to store completed or skipped MKVs:
SUCCESSMKVS=()
SKIPMKVS=()
for i in *.mkv; do
if [ -f "${i%mkv}"*"srt" ]; then
ffmpeg -i "$i" -f srt -i "${i%mkv}"*"srt" -map 0:0 -map 0:1 \
-map 1:0 -c:v copy -c:a copy -c:s srt "${i}.output.mkv"
mv "${i%mkv}"*"srt" "${i%mkv}srt".old
mv "$i" "${i}.old"
mv "${i}.output.mkv" "$i"
SUCCESSMKVS+=("$i")
else
echo $i "does not have srt file"
SKIPMKVS+=("$i")
fi
done
echo "The following MKVs succeeded:"
for mkv in "${SUCCESSMKVS[#]}"; do
echo -e "\t${mkv}"
done
echo
echo "The following MKVs were skipped:"
for mkv in "${SKIPMKVS[#]}"; do
echo -e "\t${mkv}"
done
echo

bash script order of execution
(2 answers)
Closed 7 years ago.
I will be on 3 days vacation, so I would like to do a task in one file, after it's done, launch the other one using bash script, the way I would like to do is:
List files location in one file, i.e (toDo.txt)
Once the first file is done it goes to the other one.
Example:
doDo.txt contents:
/home/me/www/some_dir/file1F42.sh
/home/me/www/another_dir/fileD2cD.sh
/home/me/www/third_dir/fileG0IU.sh
/home/me/www/last_dir/fileVFpO.sh
file1F42.sh:
some commands here
Once is done, it should jump to line 2, which is: fileD2cD.sh
I do NOT want to use cron, because I do not know when the files will finish treatment, and at the same time I do NOT want to launch all of them at once.
This is a real example that I just finish to do:
ffmpeg -i Original/$domainName"_"$fileName"_"$f-Original.mp4 -strict experimental -vf "drawtext=fontfile='/usr/share/fonts/truetype/freefont/FreeSansBold.ttf':text='www.alfirdaous.com':x="$SizeX":y="$SizeY":fontsize="$textSize":fontcolor=$textColor" -vcodec libx264 -preset medium -crf 24 -acodec copy Done/"$domainName"_"$fileName"_$f-Done.mp4
mp4Box=$(MP4Box -add Done/"$domainName"_"$fileName"_$f-Done.mp4 "$domainName"_"$fileName"_$f.mp4)
echo $mp4Box >> ffmpeg_exec.log;
# Delete Done files
rm Done/"$domainName"_"$fileName"_$f-Done.mp4
# Get master thumbnail
ffmpeg -itsoffset -150 -i "$domainName"_"$fileName"_$f.mp4 -vcodec mjpeg -vframes 1 -an -f rawvideo -s 640x480 "$silsilaName"_$f.png
n=0
for offset in 140 160 180 200 220 240 260 280 300 320
do
printf -v outfile "$silsilaName"_"$f"_"%03d.png" "$((++n))"
ffmpeg -itsoffset -$offset -i $domainName"_"$fileName"_"$f.mp4 -vcodec mjpeg -vframes 1 -an -f rawvideo -s 640x480 "$outfile"
done
ffmpeg -i "$domainName"_"$fileName"_$f.mp4 -vn -ar 44100 -ac 2 -ab 128 -f mp3 $f.mp3
done
Last command line is:
ffmpeg -i "$domainName""$fileName"$f.mp4 -vn -ar 44100 -ac 2 -ab 128 -f mp3 $f.mp3
How do I know that it is DONE, finish, so I can go to my file list "doDo.txt" and start running the next file?
#! /bin/sh
while read file; do
echo "Executing $file"
sh "$file"
done < /dev/stdin
Where usage is <script.sh> < file_list

While loop stops reading after the first line in Bash
(5 answers)
Closed 3 years ago.
I run the following bash script to rotate my mobile phone vids
while read filename ; do
nf=$(echo $filename |rev | cut -f1 -d '/'|cut -f2- -d '.' |rev)
echo $nf
rm -f ffmpeg2pass-0.log
rm -f rotate/tmp.avi
ffmpeg -i $filename -c:v libxvid -pass 1 -c:a libmp3lame -qscale:a 4 -vf "transpose=2,transpose=2" "rotate/tmp.avi"
ffmpeg -i $filename -c:v libxvid -pass 2 -c:a libmp3lame -qscale:a 4 -vf "transpose=2,transpose=2" "rotate/$nf.avi"
done <rotatelist_2
I know there are better ways to do this; I budged this together but I'm figuring out how to do the videos right so the rest don't need to look nice ;-))
However after the first run, the loop unexpectedly ends with no error message. I run similar loops for other things which work pretty well.
The echo is not called again so I guess there's something wrong with the loop itself. The linebreak in the list is a 0x0A, so it should be ok.
Use
</dev/null ffmpeg ...
</dev/null ffmpeg ...
or
ffmpeg ... </dev/null
ffmpeg ... </dev/null
to prevent ffmpeg reading from rotatelist_2 via stdin.
for f in ~/Desktop/Uploads/*.flv; do

I'm using a batch file to convert video files but I need help. What can I put in that third line that will make the batch file skip over files with flv1 video but continue onto the next file? Thanks for your help.
continue. Check the bash man page for details.
You can use the continue keyword. Have a look at the Loop Control page in the Advanced Bash-Scripting Guide
