Media Streaming Server
| Warning |
|---|
Nginx replaces Red5 is no longer as the default streaming server for since Avalon 6.3. With the upgrade to MediaElementjs 4, we now rely completely on HLS. |
By default, Avalon prechunks HLS artifacts that can be served by any webserver, see: Matterhorn's distribute-hls workflow. For development, this may suffice because a dedicated streaming server isn't necessary, however many consider prechunking inflexible and inconvenient.
For production environments, an HLS-An HLS-enabled server like Wowza, Adobe Media System Server (commercial) or Nginx + the HLS module (open-source) can take an mp4 created from distribute-streaming and stream it on the fly. Then prechunking can be disabled by commenting out the distribute-hls operation.
