----------------------------------------

             Summary: Improve performance of in-browser recording playback
                 Key: GUACAMOLE-346
                 URL: https://issues.apache.org/jira/browse/GUACAMOLE-346
             Project: Guacamole
          Issue Type: Improvement
          Components: guacamole-client, guacamole-common-js
            Reporter: Michael Jumper


The new support for in-browser playback of Guacamole recordings works well, but is slow when the recording is large due to the processing required for generating keyframes. This processing is unavoidable, but the user experience could be improved by:

# Automatically generating keyframes in the background, even when not playing video (but pausing this process when the video is playing).
# When seeking forward, leveraging the above background keyframe generation process and providing feedback, such that the browser remains responsive and users can see that the video is loading, even if that loading process is slow.
