  • Add line to FFmpeg waveform without a background

    26 février 2024, par kaif15

    I am trying to write an ffmpeg command to generate a waveform from audio. I've managed to generate the waveform but I fail when trying to add a line such that the silent areas are not blank.

    


    Currently the command is :

    


     -filter_complex "[0:a]aformat=channel_layouts=mono,compand=attacks=0:points=-80/-900|-45/-15|-27/-9|0/-7|20/-7:gain=15,showwavespic=s=180x26:colors=#7c84cc[fg];color=s=180x26:color=#303030[bg];[bg][fg]overlay=format=auto,drawbox=x=(iw-w)/2:y=(ih-h)/2:w=iw:h=1:color=#7c84cc" -frames:v 1


    


    I have added some tweaks of my own to boost the visual appeal but what I would like is to use the drawbox without the color filter. If I try to do that the line disappears during the silent part.

    


    I have also attempted to use a transparent image as the background but that failed as well.

    


    I have relied heavily on this question when approaching this problem :

  • FFMPEG on Windows faststart command line with or without a +

    24 juillet 2014, par C0nw0nk

    So on the following wiki page i see ffmpeg tells us when using faststart for HTML5 compatibility we should use a + symbol.

    https://trac.ffmpeg.org/wiki/Encode/H.264#faststartforwebvideo

    -movflags +faststart

    But looking at command line examples on here and other sites everyone puts it in their command line like this.

    ffmpeg -i C:\vidtests\Wildlife.mp4 -movflags faststart C:\vidtests\Wildlife_fs.mp4

    So my question is should it matter if the + symbol is there or not ?

  • setting encoding parameters through command line in adobe premiere [on hold]

    2 février 2016, par rishi007bansod

    Is there any command line instruction set for adobe premiere like that we have in ffmpeg encoder. I basically need to replace encoding tasks done by ffmpeg encoder in my program by adobe premiere encoder. So are there any command line instructions that can set encoding parameters(e.g. gop size, frame rate, quality parameter) in adobe premiere.
