We’ve noticed that live streams from our Axis V5915 network camera (with XLR inputs) to Wowza Streaming Engine 4.2.0 are perfectly in sync when we view them on a web page.
But…when we record the stream in Wowza ( live > Incoming Streams, then click the red circle) to an .mp4, the audio is slightly ahead (maybe .5 sec?) of the video.
See http://web.wellesley.edu/video/sync.mp4 to get a sense of what this looks/sounds like.
It’s a 1080p stream, 29.97fps.
Thanks so much for your help…k
