I am using JW player to play a wowza stream. JW Player is showing the ascpect ratio is 4:3, although the original stream is encoded in 16:9. I did some debugging and I think the problem is Wowza not sending the metadata. Here is the output from Arthropod. It seems to missing the height & width of the video. I am using rtp-live stream type.
