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

Building ffmpeg on mac results in undefined symbols
9 juin 2017, par PeterEnvironment : macOS 10.12.5, Xcode 8.3.3, pkg-config installed via brew
I need to build a minimal version of ffmpeg that supports H.264 decoding. I have downloaded the source for ffmpeg version 3.3.1 and have successfully built it for Windows and Linux. Now, I am trying to build it for mac.
The specific flags of the configuration that are relevant are :
--disable-yasm
--disable-everything
--enable-decoder=h264
--enable-decoder=h264_vda
--enable-vdaAfter running the configuration, when I run make, all the libraries such as libavcodec.a, libavfilter.a, libavformat.a, are built. However, ffmpeg itself does not get built. The error I get is :
Undefined symbols for architecture x86_64:
"_ff_vda_create_decoder", referenced from:
_vdadec_init in libavcodec.a(vda_h264_dec.o)
"_ff_vda_destroy_decoder", referenced from:
_vdadec_init in libavcodec.a(vda_h264_dec.o)
_vdadec_close in libavcodec.a(vda_h264_dec.o)
ld: symbol(s) not found for architecture x86_64Looks like the functions are defined in ./libavcodec/vda_h264.c. However, it appears vda_h264.c is never compiled. Other vda related files such as vda.c and vda_h264_dec.c do get compiled (and added to libavcodec.a).
I am thinking perhaps I am missing a configuration flag. Can someone please help ? Regards.
