CDN stream advertising by keyframe receiving
By default, all the streams published on Origin nodes are advertised to CDN and become available to select route and play right after publishing. In this case, a video stream picture resolution and aspect ratio are unknown until a publisher sends the first keyframe.
In some cases, it is necessary to know the stream picture resolution and aspect ratio on Edge server when the stream becomes available in CDN. To do this, Origin server can advertise streams after keyframe receiving since build 5.2.404. This behaviour can be enabled using the following parameter

cdn_advertise_streams_by_kframe=true |
Note that audio only streams (without video track) will not be available in CDN with this setting, because they contain no keyframes.
