FileNotFoundError : [WinError 2] The system cannot find the file specified (using ffmpeg.probe())
28 octobre 2022, par Hjalti Geir ÁgústssonI'm trying to access metadata for a video using ffmpeg.probe() and it gives this error message. There is very little info on probe online.


import os
import ffmpeg


os.chdir('E:/F/Salvaged goods/Videos/Miro/Kvikmyndir/Blade_Runner_2049.1080p.WEB-DL.H264.AC3-EVO')

pprint(ffmpeg.probe(filename='Blade_Runner_2049.1080p.WEB-DL.H264.AC3-EVO.mkv', cmd='ffprobe'))




I have also tried this, and got the same error message :


pprint(ffmpeg.probe(filename='E:/F/Salvaged goods/Videos/Miro/Kvikmyndir/Blade_Runner_2049.1080p.WEB-DL.H264.AC3-EVO/Blade_Runner_2049.1080p.WEB-DL.H264.AC3-EVO.mkv', cmd='ffprobe'))



Here is the Traceback :

Add line to FFmpeg waveform without a background
26 février 2024, par kaif15I 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 goldieI'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 :

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
