Enhancing Join.me Screen Recording for Business Meetings

As a Join.me user, I'm seeking the ability to record meetings, encompassing both screen and audio via PSTN or VOIP. Options include local recording, which is easy to implement but consumes local resources and can result in variable audio quality. Alternatively, cloud recording offers better audio stability and ease of distribution, but its implementation is complex. This document outlines the challenges of robust scaling, load balancing, and failure handling required for effective recording solutions while discussing synchronization and efficient encoding methods for optimal performance.

  1. join.me screen recording

  2. Busines requirements • I as a join.me user, I would like to record my join.me meeting • Presenter can record his/her presentation • meeting = screen and audio • audio = PSTN and/or VOIP

  3. Possible alternatives • Local recording = on the client • Pro: • Easy to implement • Con: • Consumes local resources (CPU, local disk) • Audio quality is questionable, depends on all participants connection • Distribution is hard for user • Recording in the cloud = on LMI infrastructure • Pro: • Does not consume any resource on client (CPU, local disk) • Audio quality does not depends on host connection • Distribution is easy • Con: • Implementation is hard and complex...really, I’m not kidding CONFIDENTIAL - FOR INTERNAL USE ONLY

  4. Problems to solve • Robust scaling – horizontally, verically • Load balancing • Between datacenter’s • Between in DC components • Failure handling • System must self heal in case of any error • Maintenance support: • Diagnostics • Monitoring • Component control • Environment issues • HW, hosting capabilities • Synchronization • Video & audio • Authentication • Easy changes in components, for example change video codec!? • Testing components and the whole system

  5. Solution

  6. Issues tackled • Fast encoding flow • Chunks, etc • Hosting: • NAS or no NAS • Redundant EMC systems are expensive • DFS + AppFabric = cheap NAS – assembled in China!? • AppFabric synchronization (for failover) • Custom NTP or get time from reliable source • cross DC NTP is not reliable as needed for video sync • ...

  7. Misc • Format: webm container, VP8 video, ogg/vorbis audio • Why? • Questions?

  8. Thank you
