JITSI on ARM64 (Amazon Graviton2 / aarch64)
JITSI et al. uses Java but there's no escaping a CPU-arch specific library for *coding video. You get the x86 one by default,
so it needs to be recompiled.
Seen lots of instructions out there that look complicated and are longer, change a bunch of extra settings, etc.
For AWS ARM64, much of that cruft is not needed. This is pretty simple.
As of 7/2/21, these are the *default* instructions for installing JITSI (Ubuntu LTS 20.04):
sudo -s # be root
sed -i -e 's/#DefaultLimitNOFILE.*$/DefaultLimitNOFILE=65000/' -e 's/#DefaultLimitNPROC.*$/DefaultLimitNPROC=65000/' -e 's/#DefaultTasksMax.*$/DefaultTasksMax=65000/' /etc/systemd/system.conf
systemctl daemon-reload
curl | sudo sh -c 'gpg --dearmor > /usr/share/keyrings/jitsi-keyring.gpg'
echo 'deb [signed-by=/usr/share/keyrings/jitsi-keyring.gpg] stable/' | sudo tee /etc/apt/sources.list.d/jitsi-stable.list > /dev/null
apt update
apt install -y jitsi-meet
- choose your fully-qualified hostname
- choose self-signed
- put in your email address
- make sure the fully-qualified hostname exists in DNS, Lets Encrypt plans to connect back to it to verify
Now you have a running JITSI, but the native library it's using for *coding is x86, so we just need to recompile
for aarch64:
sudo -s # be root
systemctl stop prosody jitsi-videobridge2 jicofo
apt install -y automake autoconf build-essential libtool git maven m4
apt install -y openjdk-8-jdk-headless
update-alternatives --config java # pick openjdk-8 - the one just installed
cd /tmp
git clone
git clone
mv ./usrsctp ./jitsi-sctp/usrsctp/
cd ./jitsi-sctp
mvn package -DbuildSctp -DbuildNativeWrapper -DdeployNewJnilib -DskipTests
cp jniwrapper/native/target/ ./jniwrapper/native/src/main/resources/lib/linux/
mvn package
rm /usr/share/jitsi-videobridge/lib/jniwrapper-native-1.0-*
cp ./jniwrapper/native/target/jniwrapper-native-1.0-SNAPSHOT.jar /usr/share/jitsi-videobridge/lib/jniwrapper-native-1.0-SNAPSHOT.jar
chown jvb:jitsi /usr/share/jitsi-videobridge/lib/jniwrapper-native-1.0-SNAPSHOT.jar
systemctl start prosody jitsi-videobridge2 jicofo
And that's it! Pretty simple.
If you were doing this for some other ARM64 architecture (not Amazon's), you'd just swap the ``
above with `` or whatever the `arch` command would resolve to, and it should work.
For other ARM64 platforms that have system resource constraints (like Raspberry Pi), yeah you'll have to adjust parameters
so Java is not so greedy with RAM/etc. You can google those instructions pretty easily.
