Jibir Build for FB streaming.... How to run multipal Docker instance of Jibri on Same host

1. Configure .env file and change username and password
2. Configure jibri.yml
3. docker-compose -f jibri.yml up -d --scale jibri=2
4. Now login to each instance and change .asoundrc file in /home/jibri. Change the loopback number as below....

pcm.amix { type dmix ipc_key 219345 slave.pcm "hw:Loopback_2,0,0" }

pcm.asnoop { type dsnoop ipc_key 219346 slave.pcm "hw:Loopback_3,1,0" }

pcm.aduplex { type asym playback.pcm "amix" capture.pcm "asnoop" }

pcm.bmix { type dmix ipc_key 219347 slave.pcm "hw:Loopback_3,0,0" }

pcm.bsnoop { type dsnoop ipc_key 219348 slave.pcm "hw:Loopback_2,1,0" }

pcm.bduplex { type asym playback.pcm "bmix" capture.pcm "bsnoop" }

pcm.pjsua { type plug slave.pcm "bduplex" }

pcm.!default { type plug slave.pcm "aduplex" }

Change it for each container...... 5. Some OS may need to restart docker container for changes. You can do it by below command

docker restart container_name

6. You may need to load loopback devices...

In Ubuntu 18.04 install alsa lib

apt-get install alsa

Now add below line loopback to /etc/modprobe.d/alsa-loopback.conf

options snd-aloop enable=1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1 index=0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16.

Now reload module using below command

rmmod snd_aloop -f

modprobe snd_aloop

To confirm loopback run aplay -l.... You will see all the loopback
