Best case latency? #1

Open andybarry opened 1 month ago

Have you measured the best-case latency? I'm curious what you are able to get, since I've really struggled with that on the Insta SDK. A glass to glass measurement is usually what I use since it's pretty easy to do (point the camera at the screen with a stopwatch program running along with the camera output display, take a photo with a phone, compare the difference).

@Abanesjo @Gaaaavin Any comments/suggestions?

@andybarry Thank you for your interest to the project. Currently the best case latency we get is ~187ms with raw image output and ~220ms with compressed image output. This is tested with a Insta360 X2 camera, with resolution and fps set to 1152_1152P30, and with glass-to-glass measurement. Other resolution and fps setups usually lead to a latency >1s. The annoying part with Insta360 SDK is that you don't always get the resolution and fps you specified, reference here. The 1152_1152P30 setup actually give you a 2304x1152 resolution stream from both cameras. We are still testing with other available specifications with the X3 camera.
