  • 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 :

  • Couldn't find ffmpeg or avconv - Python

    18 juin 2024, par goldie

    I'm working on a captcha solver and I need to use ffmpeg, though nothing works. Windows 10 user.

    


    Warning when running the code for the first time :

    


    C:\Users\user\AppData\Roaming\Python\Python310\site-packages\pydub\utils.py:170: RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work
  warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)


    


    Then, when I tried running the script anyway and it required ffprobe, I got the following error :

    


    C:\Users\user\AppData\Roaming\Python\Python310\site-packages\pydub\utils.py:198: RuntimeWarning: Couldn&#x27;t find ffprobe or avprobe - defaulting to ffprobe, but may not work&#xA;  warn("Couldn&#x27;t find ffprobe or avprobe - defaulting to ffprobe, but may not work", RuntimeWarning)&#xA;Traceback (most recent call last):&#xA;  File "D:\Scripts\captcha\main.py", line 164, in <module>&#xA;    main()&#xA;  File "D:\Scripts\captcha\main.py", line 155, in main&#xA;    captchaSolver()&#xA;  File "D:\Scripts\captcha\main.py", line 106, in captchaSolver&#xA;    sound = pydub.AudioSegment.from_mp3(&#xA;  File "C:\Users\user\AppData\Roaming\Python\Python310\site-packages\pydub\audio_segment.py", line 796, in from_mp3&#xA;    return cls.from_file(file, &#x27;mp3&#x27;, parameters=parameters)&#xA;  File "C:\Users\user\AppData\Roaming\Python\Python310\site-packages\pydub\audio_segment.py", line 728, in from_file&#xA;    info = mediainfo_json(orig_file, read_ahead_limit=read_ahead_limit)&#xA;  File "C:\Users\user\AppData\Roaming\Python\Python310\site-packages\pydub\utils.py", line 274, in mediainfo_json&#xA;    res = Popen(command, stdin=stdin_parameter, stdout=PIPE, stderr=PIPE)&#xA;  File "C:\Program Files\Python310\lib\subprocess.py", line 966, in __init__&#xA;    self._execute_child(args, executable, preexec_fn, close_fds,&#xA;  File "C:\Program Files\Python310\lib\subprocess.py", line 1435, in _execute_child&#xA;    hp, ht, pid, tid = _winapi.CreateProcess(executable, args,&#xA;FileNotFoundError: [WinError 2] The system cannot find the file specified&#xA;</module>

    &#xA;

    I tried downloading it normally, editing environment variables, pasting them in the same folder as the script, installing with pip, tested ffmpeg manually to see if it works and indeed it converted a mkv to mp4, however my script has no intention of running
