Subject [jira] [Commented] (GUACAMOLE-37) Add support for selecting different display qualities
Date Thu, 26 May 2016 03:52:12 GMT

    [ https://issues.apache.org/jira/browse/GUACAMOLE-37?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15301481#comment-15301481

Michael Jumper commented on GUACAMOLE-37:
-----------------------------------------

I also have some possibly-relevant experimental changes implementing dynamic quality settings
for lossy-encoded updates: https://github.com/apache/incubator-guacamole-server/compare/apache:ec93a29...glyptodon:765e05d

Interested to hear your thoughts.

>                 URL: https://issues.apache.org/jira/browse/GUACAMOLE-37
>             Project: Guacamole
>          Issue Type: New Feature
>          Components: guacamole-client, guacamole-common-js, guacamole-server
>            Reporter: Frode Langelo

> 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
