hello mmorsy,
let’s have clarification as below,
[case-1] multiple sensors per multi sessions
launch each camera sensor with different capture request, they’re not synchronized.
[case-2] multiple sensors per single sessions
using a single capture request to launch several camera frames at once.
argus_camera and MMAPI examples were based-on case-1, you’re also able to capture images from multiple cameras without issues.
you got failures with case-2, and it’s now only able to launch 3-cameras.
FYI,
here’s source limitation of scf session, you’re not able to launch all 6-cameras in a single session,
thanks
