Why would I want to disable the Premium Streaming?
There are 2 reasons why you need to consider disabling the Premium Webcam Streaming:
High CPU usage. Streaming real video on Raspberry Pi's flimsy CPU is a tricky balancing act. It is possible in some situations The Detective tries too hard at her effort to send the best quality video streams to you. This may cause excessive CPU usage and hence impact the quality of your prints.
Webcam streaming not working in OctoPrint. If, after installing Access Anywhere - The Spaghetti Detective plugin, you can no longer see webcam stream in OctoPrint, you should restart the Raspberry Pi and wait for a few minutes to see if the webcam stream will appear.
