Using WOWZAPlayer will result in more than 200% CPU usage. This is not a normal phenomenon. Is this a player issue or a problem with our live stream? I hope to have a good solution. ---

Playing on Android and web devices is no problem, and the same play address is used. In addition, “To help improve memory performance, you should disable all unused HTTP packagers. HTTP packetizers include Apple HLS, MPEG-DASH, Adobe HDS, and Microsoft Smooth Streaming.” What does this mean? I didn’t find a match. Settings options. Hope to have a solution
