    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.

    7 décembre 2018, par lala

    Reffering to Answer here (Closest Search) i have in a batch file code(below). I tried every possible way to pass line1 value to text and it simply didn’t worked. clearly hardcoding text in ffmpeg line works. Any Ideas or Guideline.

    set /p dtp="DRAG A File:"
    
set /p line1 = "Enter Top Text:"
    
set /p line2 = "Enter Bottom Text:"
    
ffmpeg -i %dtp% -filter_complex "[0:v]pad=iw:ih+100:0:(oh-ih)/2:color=white, drawtext=text='%%line1%%':fontfile=Mosk Bold 700.ttf:fontsize=24:fontcolor=black:x=(w-tw)/2:y=(50-th)/2, drawtext=text=`%line2%`:fontfile=Mosk Bold 700.ttf:fontsize=24:fontcolor=black:x=(w-tw)/2:y=h-25-(th/2)" %dtp%_tweaked.mp4

  • sh file imagemagick modification

    16 avril 2013, par Love

    I have an .sh script that generate thumbnail sprites' images from video. The below codes in the script will output the image similar this : http://s1-www.ltvimg.com/cdn/farfuture/7NO-FuBvaWJK_v34cJrAmHi6L3ywPn1YtImQNzXgTic/mtime:1362848979/sites/default/files/tooltipthumbs-sprite.jpg

    For now, the dimension of each thumbnail is 108x60, maximum 25 thumbnails(5x5) per image and per image dimension is 540x300. The thumbnail is capture every second of the video, which mean if i have a 75 seconds of video, it will output 75 thumbnails with 3 images.

    What i need now, i want the script generate only 1 image per video. Which mean 75 thumbnails all in 1 image. What i need to change on the below codes to make this works ?

    mogrify -verbose -resize 108x60 -gravity center -quality 100 -background black 
    
-extent 108x60 MONTAGE*.png
    

    
numimages=`ls -1 *.png | wc -l | cut -d " " -f1`
    

    
montage -verbose MONTAGE*.png -geometry +0+0 -tile 5x5 -quality 100 -background 
    
black "$basename"-%04d.jpg
    

    
mogrify -verbose -resize 540x300 -gravity north -extent 540x300 -quality 100 
    
-background black "$basename"-*.jpg

  • ffmpeg determine frame number for fade filter

    16 juin 2016, par Gert Gottschalk

    I am looking for an easy way to set the time points for the fade filter. Particularly for the fade-out at the end. At best would be a time based format. I understand the fade filter works based on frames. But is there a way to change that to time stamp ? Particularly in the end I have a hard time getting the number of the last frame. Some means to tell the fade filter to start the fade 0.5sec before the end would be awesome. Maybe something like :

    -filter:v 'fade=out:-0.5:0.3'

    Read : ’start fade out 0.5sec before end and have fade take 0.3sec. I.e. have 0.2sec of black at the end.

    I would also be OK if this would be in frame number counts.

    My grief right now is that the frame count i.e. reported by ffprobe seems to be somewhat half of what it really is. A fade filter applied on the count provided by ffprobe turn my video to black about half-way through the clip. I’m not sure what I’m missing there.

    Again my primary question is : How to determine the correct frame number for the fade out filter ?

    Thanks,
    Gert
