I am changing over from OpenVidu CE to OpenVidu Pro. I’ve got my pro installation on AWS up and running. On CE, I show icons on the video window using localOvPublisherObj.stream.applyFilter(‘GStreamerFilter’, {‘command’: cmd }) where cmd=‘gdkpixbufoverlay location=/work/images/mic-off-44px.png offset-x=10 offset-y=420’ Per above, the apply filter command references images that I’ve placed on the openvidu CE server in the /work/images folder. I’ve also edited the docker-compose.yaml file to include this line under kms: volumes: - /work/images:/work/images This all works great on CE. kms displays the image icons I specify as overlays on the video. My question is: How do I do this on OpenVidu Pro, since I cannot manipulate the media nodes. Is there any way? Thanks, Mike Russiello HR Avatar, Inc. ---

Hello Mike, It is quite easy if your images are pre-defined. If you know the image files you will be using, then one approach is the following one: 1. Create a custom kurento-media-server docker image, inheriting from the one used by default in the OpenVidu version you are using. For example, for OpenVidu 2.20.0, kurento-media-server:6.16.0 is used ([Releases - OpenVidu Docs](https://docs.openvidu.io/en/stable/releases/#2200)) 2. That custom image should copy the image files you need in a known path. For example /work/images. 3. Configure your OpenVidu Master Node to use your custom image, once uploaded to DockerHub. You do so like this: [On premises - OpenVidu Docs](https://docs.openvidu.io/en/stable/deployment/pro/on-premises/#change-kurento-media-server-docker-image). For example: `KMS_IMAGE=your-dockerhub-account/kurento-media-server:6.16.0-custom` This system is very easy to mantain. But it has a counterpart: your Media Nodes will take a little bit longer to launch, as the new image must be downloaded before booting up. If you want to use autoscaling or need a very quick launch in your Media Nodes for any reason, then you will have to re-generate the Media Node AMI. You ssh into a running Media Node in your AWS dashboard, download the needed images in the desired path, and generate a new AMI. Then configure your new AMI in `/opt/openvidu/.env` Master Node’s configuration file with property `AWS_IMAGE_ID` ---

Thank you Pablo. That makes sense. I am using autoscaling so have elected to modify a media node, create an ami as you described. I’ve done this and replaced the operating media node with a new one from the new ami. However, I’m still getting this error when I try to apply the filter: error gdkpixbufoverlay gstgdkpixbufoverlay.c:290 gst\_gdk\_pixbuf\_overlay\_set\_property() Could not load overlay image: Failed to open file ‘/work/images/genericperson-white-400.png’: No such file or directory 2021-11-30T20:39:22,945300 1 0x00007f2127703700 warning gdkpixbufoverlay gstgdkpixbufoverlay.c:508 gst\_gdk\_pixbuf\_overlay\_start() error: Could not load overlay image. The file is definitely in /work/images and it has full permissions. Also, I’ve edited /opt/kms/docker-compose.yml to include the path as follows: services: media-node-controller: image: openvidu/media-node-controller:5.0.0 restart: always ulimits: core: -1 entrypoint: [’/bin/sh’, ‘-c’, ‘/beats/copy\_config\_files.sh && /usr/local/bin/entrypoint.sh’] environment: - KMS\_IMAGE=kurento/kurento-media-server:6.16.0 - MEDIASOUP\_IMAGE=openvidu/mediasoup-controller:2.20.0-beta2 - METRICBEAT\_IMAGE=[docker.elastic.co/beats/metricbeat-oss:7.8.0](http://docker.elastic.co/beats/metricbeat-oss:7.8.0) - FILEBEAT\_IMAGE=[docker.elastic.co/beats/filebeat-oss:7.8.0](http://docker.elastic.co/beats/filebeat-oss:7.8.0) - OPENVIDU\_RECORDING\_IMAGE=openvidu/openvidu-recording:2.19.0 - NO\_COLOR=true ports: - 3000:3000 volumes: - /opt/openvidu/recordings:/opt/openvidu/recordings - /opt/openvidu/beats:/opt/openvidu/beats - /var/run/docker.sock:/var/run/docker.sock - /opt/openvidu/kurento-logs:/opt/openvidu/kurento-logs - ./beats:/beats - /work/images:/work/images logging: options: max-size: “100M” However, it doesn’t seem to be working. Is there somewhere else I should place the files or a different file I should edit so Kurento can find them? Thanks again, Mike ---

That’s weird. If you ssh into your new Media Node, and run `docker exec -it KMS_CONTAINER_ID bash` And go to path `/work/images` once inside the container… are the images present? If that’s the case, then this is a complete mistery. ---

Thank you. I was able to find the container id using docker container ls I was able to log in using sudo docker exec -it KMS\_CONTAINER\_ID bash which worked. When I tried to cd to /work it says no such file or directory. I also tried to cd to /opt/openvidu/recordings and that was found no problem. I noticed that /opt/openvidu/recordings is owned by root:root while /work/images was owned by ubuntu:ubuntu. All read write execute privileges were granted though. Anyway - could that be the problem? I also ran ./media\_node report and I’ve included some snippets below.

Ok, we’ve realised where the problem is just now: it is not enough to modify the docker-compose.yml file in your Media Node. The “volumes” section you have modified won’t work in the kurento-media-server container. As you can see, it is for the “media-node-controller” container (which is the controller for all the services in the Media Node). You will have to crete your own kurento-media-server image inheriting with [FROM](https://docs.docker.com/engine/reference/builder/#from), and copying the images in the desired path. Then create your new Media Node AMI with this new image already pulled, so new Media Nodes won’t have to download it from DockerHub. And don’t forget to set variable `KMS_IMAGE` in your Master Node .env configuration file. ---

Thanks for this Pablo. We decided to use image overlays via html/js rather than the gstream
