compile ffmpeg on ec2 linux instance - no libfdk-acc available
11 mai 2022, par bycI’m compiling the
ffmpeg
on an ec2 amazon linux instance, but it threw me an errorERROR: libfdk_aac not found
.

I'm following this guide http://trac.ffmpeg.org/wiki/CompilationGuide/Centos to first install the dependencies and compile the package.


yum install autoconf automake bzip2 bzip2-devel cmake freetype-devel gcc gcc-c++ git libtool make pkgconfig zlib-devel

mkdir ~/ffmpeg_sources

cd ~/ffmpeg_sources
curl -O -L https://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2
tar xjvf ffmpeg-snapshot.tar.bz2
cd ffmpeg

make
make install
hash -d ffmpeg



and this is the error message I've got

I tried installing
libfdk_aac
but there's no package found. I don't seem to come across any posts discussing this issue, or at least recently. Appreciate any pointers. thanks !

[ec2-user@ip-xx-xxx-xx-xx ffmpeg]$ sudo yum install libfdk-aac

How to "extend" aws docker base image (.net core from scratch) by ... libs/ubuntu/ffmpeg ?
26 avril 2022, par Nigrimmisti would like to use AWS Lambda through the image containers using .net core 3.1 and it is works fine for me in simplest code case. But i stucked with next scenario :


By default, aws provide base image with .net core with aws libs based on "from scratch". So as i know, it minimal Linux that does not contains even package manager.


I need to work with ffmpeg in the code, but to do it i need to install few packages and ... fmpeg. I have working code on image


FROM mcr.microsoft.com/dotnet/runtime:3.1-bionic



It is ubuntu with .net core runtime. But what is the right strategic in case of AWS Lambda image ? How can i ... merge them ?.


Have few ideas, but not sure :


- 

- use as is
FROM public.ecr.aws/lambda/dotnet:core3.1
and try to install package manager, all depenendencies to use ffmpeg and so on ? - Use
mcr.microsoft.com/dotnet/runtime:3.1-bionic
, somehow add required by amazon dependencies (how ? download content and attach from local ?) and configure it to run in Lambda runtime ? - ... ?








Will be glad to hear where is the solution here. Thanks !


- use as is
