• FFMPEG converting all files in a folder and generating the output into another folder

  5 avril 2023, par User

  Have generated the following code by searching on the web ; unfortunately there is some mistake here,maybe basic, that isn't allowing the code to run.

  


  the code is supposed to :
  
1.work on all files inside the fodler
  
2.convert the files into a 1x1 video ( works alone )
  
3.the generated video will be sent to a specific fodler named \sub , a subfolder inside the main folder

  


  for i in *.mp4; do  
  ffmpeg -i "$i" -codec:v libx264 -preset fast -b:v 7500k -filter:v "crop=in_h:in_h" -maxrate 10000k -codec:a aac "sub\fixed-$i.mp4"; 
done 


  


  the output is :

  


  i was unexpected

  


  tried searching on the web trough similiar questions

  


• Setting image duration with -t

  3 septembre 2020, par ottpeter

  I am generating an ffmpeg command with bash. This is how I'm generating the input list :

  


  INPUT_LIST=""
for file in $VIDS_PATH*
do
    if [ ${file: -4} == ".jpg" ]
    then
        INPUT_LIST="${INPUT_LIST} -t $IMAGE_DURATION -i $file"
    else
        INPUT_LIST="${INPUT_LIST} -i $file"
    fi
done


  


  And then the filter complex is generated like this :

  


  [$i:v]scale=$RES_X:$RES_Y:force_original_aspect_ratio=1,pad=wi   dth=$RES_X:height=$RES_Y:x='if(lt(in_w,in_h),$PADDING,0)':0,setsar=1[v$i];


  


  I want images to last for 10 seconds. Now images are only lasting for 1 frame.

  


  The generated input list looks something like this :

  


  -i /PATH/World_Map_Perspective_1_4K_preview.mp4 -i /PATH/preview.mp4 -i /root/vids/301img.jpg -t 10


  


  Why is this not working ?

  


• ffmpeg Error : Pattern type 'glob' was selected but globbing is not support ed by this libavformat build

  14 septembre 2017, par Aryan Naim

  I’m trying to convert group of ".jpg" files acting as individual frames into 1 single mpeg video ".mp4"

  Example parameters i used :

  frame duration  = 2 secs
  
  frame rate      = 30  fps
  
  encoder         = libx264 (mpeg)
  
  input pattern   = "*.jpg"
  
  output pattern  = video.mp4

  Based on ffmpeg wiki instructions at (https://trac.ffmpeg.org/wiki/Create%20a%20video%20slideshow%20from%20images), I issued this command :

  ffmpeg -framerate 1/2 -pattern_type glob -i "*.jpg" -c:v libx264 -r 30 -pix_fmt yuv420p video.mp4

  But I’m getting this error :

  [image2 @ 049ab120] Pattern type 'glob' was selected but globbing is not 
  
  supported by this libavformat build *.jpg: Function not implemented

  Which probably means the API pattern matching commands for my build/version have changed. By the way this my windows 32bit ffmpeg download build (ffmpeg-20150702-git-03b2b40-win32-static).

  How can I choose a group of files using pattern matching using ffmpeg ?
