Vuforia Chalk video quality and network connectivity
Hi, I am looking for an answer on two questions that relate to Chalk video performance and network connectivity:
When two users communicate with Chalk, is the video transmitted directly from user device to user device, or rather is an intermediate PTC Chalk server used between the users?
The Vuforia Chalk Best Practices topic in the Help recommends "high bandwidth connections" for best performance which is neither specific nor objective. Assuming iPhone 8 devices for each user, what is the maximum video size (e.g. 4k, 1080p) and frame rate (e.g. 24, 30, 60 fps) that Chalk will transmit video, and also what is the minimum? What network bandwidth is recommended to obtain high quality video at the maximum video size and frame rate?
