  • Audio equalizer using FFmpeg

    28 septembre 2015, par Evgeniy Kharchenko

    I’m developing audio player using FFmpeg. I want to add audio equaliqer to my app, but I don’t know how to do it. I know that FFmpeg has a FFT functions, but I have count of samples that not mutch with any power of 2. I also tried to use other FFT libraries, but I have some noise on my audio after equalization.
    Can anybody help me to understand how to use FFmpeg’s FFT functions or any oter ways to implement audio-eq using FFmpeg ?

  • Setting dpi flag in image files generated using ffmpeg

    17 mars 2023, par jim_e_jib

    We're using ffmpeg to batch out some TIFF images that are being resized and having white borders created to fit specific paper sizes.

    


    The resulting images default to 72dpi, even when the source is 300dpi. Is there a way to set the dpi flag in the output file ?

    


    Many thanks :-)

    


    The command we're using :

    


    for %%a in ("*.tif") do ffmpeg -i "%%a" -vf "scale=6974:4919:force_original_aspect_ratio=decrease,pad=7016:4961:(ow-iw)/2:(oh-ih)/2:color=white, format=rgb24" "%%~na A2 poster 594x420mm-Border.tif"


    


    We have tried using -dpi 300 in the code but get the error that this is not a recognised.

    


    Edit :

    


    I have just managed to answer my own question :

    


    for %%a in ("*.tif") do ffmpeg -i "%%a" -vf "scale=6974:4919:force_original_aspect_ratio=decrease,pad=7016:4961:(ow-iw)/2:(oh-ih)/2:color=white,format=rgb24" -dpi 300 "%%~na A2 poster 594x420mm-Border.tif"


    


    I had been placing the -dpi 300 in the wrong place when I'd tried it...
