  • Get and manipulate ffmpeg volume detect output in bat file

    20 février 2024, par NTProductions

    I have a bat file which runs the volumedetect filter :

    


    ffmpeg -i C:\Users\Nate\Videos\VideoClips\1080p-47243316.mp4 -filter:a volumedetect -f null /dev/null


    


    Is it possible to capture all this output text it sends to cmd, and manipulate it to the point of storing say, the mean_volume into a variable ?

    


    Volumedetect output example :

  • How to detect audio volume using humble-video library ?

    21 octobre 2016, par Sonny MT

    I’m coding a Java sample to get audio volume data (in decibel) from a video file for some analysis using "ffmpeg" functions.
    It is workable using "ffmpeg" command line, as below :

    ffmpeg.exe -af volumedetect -f null -y null -i d:\test.mp4

    Output of ffmpeg.exe :

    video:3358kB audio:158568kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown

    I’ve found that humble-video is a good Java wrapper of ffmpeg with samples at https://github.com/artclarke/humble-video/blob/master/humble-video-demos/src/main/java/io/humble/video/demos/DecodeAndPlayAudio.java

    How and where can I get those audio volume data (same as volumedetect option) with humble-video ?

  • How do I mix multiple audio tracks mit FFMPEG and adjust each volume ?

    4 avril 2022, par doppelzwei

    Let's say I have an input .mp4 file that contains 4 audio tracks.
How can I change their volumes independently and convert it to a new file that just contains all the 4 audio tracks mixed together and stored in the first audio track ? For example I want the first, second and third audio tracks from the input file to be double their original volume and the fourth to be half its original volume, all saved in the output files first audio track. How would that command look like ?
