The answer I received for you @Terry Longordo
HLS chunks that contain video are normally supposed to always start on keyframes to allow seamless switching across bitrate renditions (for ABR). But depending on where the WSE happens to join the stream, the first video packet received is rarely a keyframe, so the first chunk typically does not start on a keyframe.
That log code was added mainly to alert in the case where WSE stopped receiving keyframes and we had to force the ending of a chunk. So seeing many of these in the logs for the same stream indicates a significant issue, but just one at the beginning is normal.
If you are experiencing issues with audio only and no video, the only support we can provide is through a support ticket. We cannot solve this through the forums.
