We are using video room plugin for webinars: one publisher - many subscribers. Everything is fine when we have less then 1000 subscribers. But when we have more then 1000 subscribers in a room, the quality on video became worse. And we cannot figure out why publisher send video with lower quality.
Have anybody had the same problem?
What indicators do we need check in a browser or Janus to understand why publisher is sending video with lower quality?
How to force publisher to send video with constant quality?
Thank in advance for any advice.
As already explained in response to other posts (please make sure to use the search feature), the VideoRoom plugin is not optimized for large scale broadcasting. It has some bottlenecks in critical paths that make it struggle when numbers go up, since it’s conceived for rooms, rather than 1-to-many. Either use the VideoRoom for ingestion, and the Streaming plugin for broadcasting (using RTP forwarding and helper threads), or try the experimental helper threads feature in the VideoRoom plugin.
