  • Use ffmpeg to apply blend overlay to the last PNG

    28 août 2022, par Gregory

    I am currently overlaying a list of PNGS to generate a final PNG file with ffmpeg using the following command :

    


    ffmpeg -i a1.png -i a2.png -i a3.png -i a4.png -i a5.png -i a6.png -y \
-filter_complex \
  [0:v][1:v]overlay=format=auto[v1];\
  [v1][2:v]overlay=format=auto[v2];\
  [v2][3:v]overlay=format=auto[v3];\
  [v3][4:v]overlay=format=auto[v4];\
  [v4][5:v]overlay=format=auto,split[s0][s1];\
  [s0]palettegen[p];\
  [s1][p]paletteuse[f1] \
-map [f1] out/assets/1.webp


    


    Now, I would like to apply a blend=all_mode='overlay' to the last PNG (a6.png). I tried the command below but throwing an error. Any idea what i'm doing wrong ?

    


    ffmpeg -i a1.png -i a2.png -i a3.png -i a4.png -i a5.png -i a6.png -y \
-filter_complex \
  [0:v][1:v]overlay=format=auto[v1];\
  [v1][2:v]overlay=format=auto[v2];\
  [v2][3:v]overlay=format=auto[v3];\
  [v3][4:v]overlay=format=auto[v4];\
  [v4][5:v]overlay=format=auto[v5];\
  [v4][v5]blend=all_mode='overlay'[vv5];\
  [vv5]split[s0][s1];\
  [s0]palettegen[p];\
  [s1][p]paletteuse[f1] \
-map [f1] out/assets/1.webp


    


    Error: ffmpeg exited with code 1: Stream specifier 'v4' in filtergraph description


    


    Thank You

    


  • ffmpeg libcdio input device under windows

    18 avril 2020, par Tobias Brohl

    I'd like to use the ffmpeg tools for cd stuff under windows, however I was unable to provide working -i parameter (My CD Drive is F :~; I tried F :\ and F :\Track01.cda) :
[libcdio @ 043fe2a0] Could not open drive F:\
[libcdio @ 0635c2e0] Could not open drive F:\Track01.cda
Does anyone know what to use as -i parameter under windows with libcdio ?

    


  • lavfi/drawtext : ignore final LF of textfile.

    30 novembre 2020, par Nicolas George
    lavfi/drawtext : ignore final LF of textfile.

    A standard text file ends with a final LF.
    
Without this change, it is interpreted as an empty final line,
    
and visible with the box option.
    
The current behavior can be achieved by actually having
    
an empty line at the end of the file.
    

    Fix trac ticket #7948.
