• lavfi : new colorspace conversion filter.

  6 avril 2016, par Ronald S. Bultje

  lavfi : new colorspace conversion filter.
  The intent here is similar to colormatrix, but it’s LGPLv2.1-or-later
  
  (instead of GPLv2.0) and supports gamma/chromaticity correction.

• Batch file : FOR loop not working to concatenate mp3 and mp4

  7 janvier 2023, par Ionut Bejinariu

  mp3list-1.txt contain the full patch to the mp3 files that will be concatenated

  


  mp4list-1.txt contain full path to the mp4 files that will be concatenated

  


  then both results mergedmp34.mp3 and mergeMp4.mp4 should be combined together in a final MP4 video file with a random name.

  


  something I do wrong I don't understand what

  


  my guess I do something wrong on FOR loop.

  


  sometimes my .txt files contain full path to a single file mp4 or mp3

  


  if don't have what to combine will concatenate 1 single file ?

  


  set exportdir=
set batsource= the place where this batch file is

1< mp3list-1.txt 2< mp4list-1.txt (
    FOR %%A in ("%batsource%") DO (
        set /p mp3list=" <&1
        set /p mp4list=" <&2
        ffmpeg -f concat -safe 0 -i "!mp3list!" -c copy mergedmp34.mp3
        ffmpeg -f concat -safe 0 -i "!mp4list!" -c copy mergeMp4.mp4
        ffmpeg -i mergedmp34.mp3 -i mergeMp4.mp4 -map 0:v -map 1:a -vcodec copy -c:a aac -b:a 320k "%exportdir%\%RANDOM%.mp4"
        del mergedmp34.mp3
        del mergeMp4.mp4
 
         
    )
)



  


  mp4list-1.txt

  


  F:\.....Videos-115\output-mp4.txt
F:\....\Videos-1150\output-mp4.txt
F:\.....\Videos-1151\output-mp4.txt
F:\......Videos-1152\output-mp4.txt


  


  mp3list-1.txt

  


  F:\......audio-52\output-mp3.txt



  


  and .txt with direct files are like :

  


  file 'F:\....00OH7011.mp3'
file 'F:\....00OH7011.mp3'
file 'F:\....00OH7011.mp3'


  


  and for videos

  


  file 'F:\....00OH7011.mp4'
file 'F:\....00OH7011.mp4'
file 'F:\....00OH7011.mp4'


  


  Later Edit
basically, I want to adapt to my needs the above script based on this working script bellow where I have 4 txt files that are looped.

  


  mkdir ".\Export"
set "sourcedir="  
set "outputdir=Export"

1< codfundal.txt 2< fontalbum.txt 3< album.txt 4< artist.txt (for %%F in (*.jpg *.jpeg) do (
set /P "artist=" <&4 
set /P "fontalbum="<&2  
set /P "album=" <&3
set /P "codfundal=" <&1
   
   
   magick convert -gamma 1 -contrast 30 %%F -fill white -undercolor  "!codfundal!"  -gravity Center -font "!fontalbum!" -pointsize 215   -annotate +0+5  "!album!"  -gravity Center -pointsize 120 -font "Calibri-Bold" -annotate +0+220 "!artist!" -crop 1440x1440+0+0   -quality 92 "%outputdir%\%%F"
