Let me update the answer with the Ant Media Server v2.14.0

Download the ffmpeg-7.1-1.5.11-linux-x86_64-gpl.jar from Maven Repository or ask help to get the latest version from support team
Copy the jar file to your to /usr/local/antmedia/plugins folder, and grant the antmedia user access to the file.

sudo chown -R antmedia:antmedia /usr/local/antmedia/plugins

Remove the old file ffmpeg jar

sudo rm /usr/local/antmedia/plugins/ffmpeg-7.1-1.5.11-linux-x86_64.jar

Login the webpanel and go to the advanced settings of application that you use such as live' and change encoderNamefrom empty tolibx264`

 "encoderName": "libx264",

Click the save button and do not forget to add some ad…

AMS uses the libopenh264 encoder by default starting with v2.5.1. Prior to v2.5.1, the default encoder was libx264. Please follow the steps below to utilise the x264 encoder in subsequent versions.

Get the FFMPEG jar file.

Download the file for version 2.5.1 and 2.5.3 from here.
Download the jar file for version 2.6.0 and higher from here.

Now, copy the jar file to your AMS and place it in the /usr/local/antmedia/plugins folder, and grant the antmedia user access to the file.

sudo chown -R antmedia:antmedia /usr/local/antmedia/plugins
After copying the file, add the property listed below to the'red5-web.properties' file in the '/usr/local/antmedia/webapps/App-Name/WEB-INF' folder.

settings.encoding.encoderName=libx264

Please restart the server after making the modifications.
After publishing the stream, you should see the following logs.

2023-05-10 23:47:50,243 [vert.x-worker-thread-24] INFO i.a.e.adaptive.video.H264Encoder - encoder name: libx264 for stream:test

Don't forget to add ABR (to see libx264 in the log file.) :)

Here is a script to convert libopenh264 to libx264

#!/bin/bash
#
# Change libopenh264 to libx264 for all apps
#

v25="https://antmedia.io/libx264/ffmpeg-linux-x86_64-gpl.jar"
v26="https://antmedia.io/libx264/ffmpeg-5.1.2-1.5.8-linux-x86_64-gpl.jar"
PLUGIN_DIR="/usr/local/antmedia/plugins"
AMS_BASE="/usr/local/antmedia/"

VERSION=$(unzip -p $AMS_BASE/ant-media-server.jar | grep -a "Implementation-Version"|cut -d' ' -f2 | tr -d '\r')


if [ "$(printf '%s\n' "2.6" "$VERSION" | sort -V | head -n1)" = "2.6" ]; then
	wget $v26 -P $PLUGIN_DIR
else
	wget $v25 -P $PLUGIN_DIR
fi

chown -R antmedia.antmedia /usr/local/antmedia/plugins/

LIST_APPS=`ls -d $AMS_BASE/webapps/*/`

for i in $LIST_APPS; do
	echo "" >> $i/WEB-INF/red5-web.properties
	echo "settings.encoding.encoderName=libx264" >> $i/WEB-INF/red5-web.properties
done

systemctl restart antmedia
