ERROR: aom >= 1.0.0 not found using pkg-config

[sergiks]

Under Amazon Web Services Amazon Linux AMI 2018.03 on EC2 t2.micro instance I was trying to compile ffmpeg for use with AWS Lambda.

sudo yum update -y
sudo yum groupinstall -y "Development Tools" "Development Libraries"
bash <(curl -s "https://raw.githubusercontent.com/markus-perl/ffmpeg-build-script/master/web-install.sh?v1")

Command went well including "building ffmpeg ... Done" but failed after that with error

ERROR: aom >= 1.0.0 not found using pkg-config

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.

I tried updating the build_ffmpeg script with the "aom" url for refs/tags/v1.0.0-errata1:

https://aomedia.googlesource.com/aom/+archive/add4b15580e410c00c927ee366fa65545045a5d9.tar.gz

Deleted packages/aom-build and packages/av1* and re-run build_ffmpeg --build
but even with that "patch" module version looks old:

PKG_CONFIG_PATH="/home/ec2-user/ffmpeg-build-script/packages/aom_build/"   pkg-config --modversion aom
0.1.0

Temporary solution for me was to edit build-ffmpeg: line 376 change from

--enable-libaom

to

--disable-libaom

Eventually built ffmpeg runs perfectly under AWS Lambda.

Hi Sergiks,

Due to the lack of time and resources, I can currently only support the following platforms:

Mac OSX 10.14 64Bit XCode 10.1
Debian 9.4

You can also try to compile FFmpeg on a Debian machine and then copy the resulting binaries to your EC2 instance.
