  • ffmpeg concatenate images in one image

    26 juillet 2016, par drlexa

    I use this to get frames from video and concatenate them in one image :

    ffmpeg -i output.mp4 -vf 'fps=2,tile=1000x1' out.jpg

    But there is a problem : I do not know number of frames that will be fetched. Here I hardcoded tile size 1000x1, but if there will be more than 1000 frames, then will be an error. Before starting ffmpeg I do not know actual size of tile.

    So I want use command like :

    ffmpeg -i output.mp4 -vf 'fps=2,tile=*x1' out.jpg

    That means : I want you to concatenate ALL images that will be fetched in one row, but I cannot use * as an argument for tile.

    Is there some way to solve my problem ?

  • Concatenate images as well as crop video in single ffmpeg command

    16 septembre 2022, par Loma Harshana

    I have a set of images that I concatenate into a video using the following command (not sure of all the options just copied it from another answer) :

    


    ffmpeg -framerate 24 -pattern_type glob -i "/path/to/input/????.png" \
-c:v libx264 -profile:v high -crf 20 -pix_fmt yuv420p "/path/to/output/output.mp4"


    


    Now I want to crop this video to 500x500 size starting from 0,0, which I can do with the following :

    


    ffmpeg -i "/path/to/input/input.mp4" -vf "crop=500:500:0:0" "/path/to/output/output.mp4"


    


    How can I combine the above two operations in a single ffmpeg command.

    


  • FFMPEG merging sounds with amix cause volume problem [duplicate]

    10 mars 2020, par birdcage

    I am trying to combine many sounds with FFMPEG amix command and I need to set the starting moment of every sound. Every sound has different duration.

    When I use the command below, the volume of first and last item seems different in merged file. It seems the level of sound increases till the end of merged sound. I am wondering what I do wrong.

    ffmpeg -i 1.wav -i 2.wav -i 3.wav -i 4.wav -filter_complex
