• Bash script to text watermark video from filename (ffmpeg)

  13 juin 2016, par Yian

  I would like to automate some text to be ’watermarked’ on my videos. Basically I want to create a marker in my file names (eg "&&"). Then I want the script to take the content after "&&" and place it in the "drawtext" content.

  For example, file named "Video2132 && The First Test" would make the part after "text=" become "The First Test".

  The below code works fine without the drawtext part.

  As soon as I add that function, the script runs, but it creates empty video files (zero bytes).

  for f in ./*.mov; do
  
      printf '%s\n' "Doing stuff with: ${f}"
  
  
  
      i='0'
  
      while (( i <= 5 )); do
  
          ffmpeg -ss "$(( i * 25 ))" -t 25 -i "${f}" -acodec copy -vf drawtext="fontfile=/Users/mac1/Library/Fonts/Gillsanslight.ttf: \
  
  text='Stack Overflow': fontcolor=white: fontsize=24: box=1: boxcolor=black@0.5: \
  
  boxborderw=5: x=(w-text_w)/2: y=(h-text_h)/2" -codec:a copy "${f%.mov}.${i}.mov" -loglevel quiet
  
          (( i++ ))
  
      done
  
  done

• ffmpeg not working in script - moov atom not found

  2 juin 2016, par user1490563

  I made a simple script that divides a flv file into multiple parts, converts them all to .mp4 individually and then merge all of them to form a final mp4 file. I did this to save time and convert large files in parallel.

  However, I am stuck because the command that normally runs on command line for ffmpeg, doesn’t run via script.

  I am kind of stuck here and will like to have some assistance.

  #!/bin/bash
  
  
  
  
  
  #sleep 5
  
  
  
  
  
  filenametmp=$1;
  
  
  
  filename=`echo "$filenametmp" | awk '{split($0,a,"."); print a[1]}'`
  
  
  
  
  
  echo $filename
  
  
  
  output="$filename-output"
  
  
  
  filenamewithoutpath=`echo "$output" | awk '{split($0,a,"/"); print a[4]}'`
  
  
  
  echo $output $filenamewithoutpath
  
  
  
  /usr/bin/ffmpeg -i $filenametmp -c copy -map 0 -segment_time $2 -f segment $output%01d.flv
  
  
  
  #sleep 10
  
  
  
  
  
  #echo "/bin/ls -lrt /root/storage/ | /bin/grep $filenamewithoutpath | /usr/bin/wc -l"
  
  filecounttmp=`/bin/ls -lrt /opt/storage/ | /bin/grep $filenamewithoutpath | /usr/bin/wc -l`
  
  
  
  filecount=`expr $filecounttmp - 1`
  
  
  
  echo $filecount
  
  
  
  for i in `seq 0 $filecount`
  
  do
  
  
  
  
  
  suffix=`expr 0000 + $i`
  
  
  
  filenametoconvert="$output$suffix.flv"
  
  convertedfilename="$output$suffix.mp4"
  
  echo $filenametoconvert

  done
  
  
  
  
  
  
  
  
  
  
  
  sleep 5
  
  
  
  concatstring=""
  
  
  
  for j in `seq 0 $filecount`
  
  do
  
  
  
  
  
  suffix=`expr 0000 + $j`
  
  
  
  convertedfilenamemp4="$output$suffix.mp4"
  
  
  
  #concatstring=`concat:$concatstring|$convertedfilenamemp4`
  
  
  
  echo "file" $convertedfilenamemp4 >> $filename.txt
  
  
  
  #ffmpeg -i concat:"$concatstring" -codec copy $filename.mp4
  
  
  
  #ffmpeg -f concat -i $filename.txt -c copy $filename.mp4
  
  
  
  
  
  done
  
  
  
  echo $concatstring
  
  
  
  ffmpeg -f concat -i $filename.txt -c copy $filename.mp4
  
  
  
  
  
  rm $output*
  
  rm $filename.txt

  I run any flv file like this :

  ./ff.sh /opt/storage/tttttssssssssss_573f5b1cd473202daf2bf694.flv 20

  I get this error message :

  moov atom not found

  I am on Ubuntu 14.04 LTS version, standard installation of ffmpeg.
