High CPU usage on iOS

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.

Thank you for contacting Wowza Support regarding high CPU usage.

We have a few articles that may help you with performance. The first one is in regards to what your system recommendations are. We also recommend having 2GB per core.

To help with memory performance you should disable any and all HTTP packetizers that are not in use. HTTP packetizers include Apple HLS, MPEG-DASH, Adobe HDS, and Microsoft Smooth Streaming.

Also, we’d be curious what you experience when you use a different player. Have you tried that?

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
