Subject [jira] [Commented] (GUACAMOLE-37) Add support for selecting different display qualities
Date Thu, 26 May 2016 15:25:13 GMT

Frode Langelo commented on GUACAMOLE-37:
----------------------------------------

This I like!

Optimally, the dynamic quality selection would be for both "normal" and "lossy" encoded updates.
Going down this path, there should be a UI for selecting dynamic quality settings or manual.

>             Project: Guacamole
>          Issue Type: New Feature
>          Components: guacamole-client, guacamole-common-js, guacamole-server

> The current adaptive encoding greatly reduces bandwidth usage and improves the user experience.
> It would be great to be able to choose different quality settings for a user inside a
Guacamole session, in cases where a user is in a low bandwidth/high latency environment.
> Example quality options could be:
> High: PNG (normal) / JPEG q90 (adaptive)
> Medium: JPEG q90 (normal) / JPEG q60 (adaptive)
> Low: JPEG q60 (normal) / JPEG q40 (adaptive)
> This feature would involve:
> - add UI to select quality
> - API to guacamole-server to control quality setting
> - plumbing for quality settings in guacamole-server
> - handle separate qualities per user (because of session sharing)
> - repair of lower quality areas of the screen (from adaptive encoding) with higher quality
