  • FFmpeg image2 output : Control JPG image quality when using mjpeg_qsv

    11 avril 2022, par clic

    My FFmpeg command ouputs a series of JPG images. Simplified :

    


    


    ffmpeg -f dshow -video_size 3840x2160 -framerate 25 -i "video=My
Webcam" -qscale:v 5 -vcodec mjpeg_qsv "C :\out\%d.jpg"

    


    


    I want to use -vcodec mjpeg_qsv to leverage GPU acceleration. Usually (without "_qsv") I can control JPG image quality by using qscale:v , but it seems to have no effect in combination with mjpeg_qsv.

    


    Is it even possible to control JPG image quality when using mjpeg_qsv ? If yes, any ideas how ? Thanks !

    


  • FFMPEG mixing .wav files volume control [closed]

    1er avril 2024, par JoonSeo Yang

    I am working on Java, using the ffmpeg library with command line processing to mix 2 .wav files into one .wav file, but I would like to know how to control the volume of each original file.

    


    My problem : i have 2 audio files (human voice BGM), but BGM is too loud, so i can barely hear human voice, i would like to -> volume down the BGM file, or volume up voice file

    


    Here is my partial code

    


    String ffmpegCommand = file_exe.getAbsolutePath()
    + String.format(
        " -i %s -i %s -filter_complex amix=inputs=2:duration=first:dropout_transition=3 %s",
        file_1.getAbsolutePath(), file_2.getAbsolutePath(), outputFilePath);
Process process = Runtime.getRuntime().exec(ffmpegCommand);


    


    it is quite simple code. I need help on this, and it would be very thankful to which document to read to get such information

    


    PS.sorry for my poor eng.. Im not native :D

    


    I was wandering around documentations, but its quite hard to find what i want
