Below is dockerfile with installation details of ffmpeg.

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim AS base

RUN sed -i 's/deb.debian.org/mirrors.ustc.edu.cn/g' /etc/apt/sources.list \
    && apt-get update \
    && apt-get install -y ffmpeg \
    && apt-get clean && apt-get autoclean && apt-get autoremove \
    && rm -rf /var/lib/apt/lists/*

RUN apt-get update && apt-get install -y libgdiplus libc6-dev && ln -s /usr/lib/libgdiplus.so /usr/lib/gdiplus.dll
WORKDIR /app
EXPOSE 80
EXPOSE 443
...

How can I install different ffmpeg package, more specifically alfg/ffmpeg in that way to preserve the rest of the dockerfile intact and with same installation path /usr/bin/ffmpeg.

EDIT

Here's my Dockerfile

not sure with this changes what is the path for ffmpe binaries. With the old Dockerfile (1st in this example) it worked fine (when it comes to finding ffmpeg binaries). It was referenced from the code like this

string ffmpegPath = "/usr/bin/ffmpeg";
string ffprobePath = "/usr/bin/ffprobe";

Now with new dockerfile I'm getting

System.ComponentModel.Win32Exception: 'An error occurred trying to start process '/usr/bin/ffmpeg' with working directory '/app'. No such file or directory Obviously I need to change path to match the new installation path, tried with /opt/ffmpeg but that doesn't work.

CodePudding user response：

You can find the Dockerfile for their build here https://github.com/alfg/docker-ffmpeg/blob/master/Dockerfile.

Maybe you can copy parts of their dockerfile into yours.

Here's my attempt. I switched your aspnet image to alpine since the ffmpeg dockerfile is alpine and changing package managers seemed like a big task.
