• Docker alpine : ffprobe not found in $PATH

  5 mars 2023, par Harun Sasmaz

  I have a Go program that executes ffmpeg and ffprobe commands, so I need to install them in my Docker container.

  


  Here is my Dockerfile :

  


  FROM golang:1.17.7-alpine

WORKDIR /src
COPY go.mod go.sum ./
RUN go mod download
COPY . .
RUN go build -o ./server cmd/service/main.go

RUN apk update
RUN apk upgrade
RUN apk add --no-cache ffmpeg

FROM alpine
COPY --from=0 /src/server /usr/bin/server
CMD ["server"]


  


  However, when I run container, it says :

  


  exec: "ffprobe": executable file not found in $PATH


  


  How can I fix it ?

  


• FFMPEG audio not delaying properly

  1er avril 2022, par Spartan 117

  I am trying to mix two audio files together, with one audio being delayed. Here are the file details

  


  Audio 1 - https://pastebin.com/vkYsH88e, "startTime" : "03/23/2022 21:20:27", "endTime" : "03/24/2022 01:06:11"

  


  Audio 2 - https://pastebin.com/Gs4V96GQ, "startTime" : "03/24/2022 01:05:30", "endTime" : "03/24/2022 04:21:41"

  


  As you can see from the paste bin and the json property, Audio two starts about 3 hours and 45 minutes after Audio one, here is how i am trying to mix them

  


  ffmpeg -i RTb295d0534191e1acb22a45bb971a12e6.mka -i RT103bfe5f4b129860f69cd8e820f3a10b.mka -filter_complex "[1:a]adelay=13500s:all=1[apad]; [0:a][apad]amix=inputs=2:weights=1|1[aout]" -map [aout] combined_audio.mka


  


  Here is the output of that mixture - https://pastebin.com/KAsw0905

  


  Files have been uploaded here, if anyone wants to test - https://easyupload.io/m/xveng4

  


  The issue i'm having ? Based on the parameters provided, the 2nd audio file should start playing after 3 hours and 45 minutes. Instead, it plays after 5 hours and 45 minutes. I'm new to FFMPEG and have been having trouble figuring this out. Any ideas ?

  


• python modules ffmpeg and ffprobe are installed but youtube-dl not able to find

  12 avril 2022, par Akshay Hiremath

  I'm using python 3.8 on MacOS Big Sur

  


  I installed python module package for youtube-dl with

  


  pip3 install -upgrade youtube-dl


  


  I wanted to do post processing on the content downloaded so I installed python packages ffprobe and ffmpeg.

  


  pip3 install ffprobe

  pip3 list 
Package    Version   
---------- ----------
ffmpeg     1.4       
ffprobe    0.5           
youtube-dl 2021.12.17 


  


  Still it is complaining can't find ffprobe and ffmpeg :

  


  youtube_dl.utils.DownloadError: ERROR: ffprobe/avprobe and ffmpeg/avconv not found. Please install one.


  


  I see both packages in /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/

  


  Trying to figure out what am I doing wrong. Many other answers to similar questions on SFO are suggesting installing these packages in the OS using brew etc. but in my case "I want to do everything through python". So shouldn't just installing python modules be enough ?
