Hello.

I implemented my app on openvidu pro 2.14.

I’d like to use kms filter functions.

I tried to install kms filter packages but couldn’t

apt-get install kms  
Reading package lists… Done  
Building dependency tree  
Reading state information… Done  
E: Unable to locate package kms

I referred to this document.

[https://docs.openvidu.io/en/2.14.0/advanced-features/filters/](https://docs.openvidu.io/en/2.14.0/advanced-features/filters/)  
[https://doc-kurento.readthedocs.io/en/stable/features/kurento\_modules.html#module-tutorial-chroma-filter](https://doc-kurento.readthedocs.io/en/stable/features/kurento_modules.html#module-tutorial-chroma-filter)

and I found some bug issue in the Kurento bugtracker.

Is there anyone who use kms filter?

Hello @richard,

we plan to improve the procedure to install filters in dockerized Kurento in the following days. We will notify you.

Thank you so much. 😃

And I have another question.

I used FaceOverlayFilter on my publisher stream.

The image quality is so much lower than original image.

I set the maximum send/receive bandwidth to 3600 Kbps.

What is the best way to improve the image quality?
