ZED SDK 4.2 async_image_retrieval

Software
1

Hello there! First of all thank you ZED team for this update! I have noticed a new an exciting parameter on InitParameters called async_image_retrieval. I was wondering how the grab / retrieve operations should be called when this feature is enabled.

Should we also call a grab each frame? Retrieve image can get new images now? Can we get depth without affecting image output?

Thanks for reading

Hi @arremebg
normally when using this behavior you have a thread that calls the grab function continuously to perform the ZED SDK internal processing at the grab rate, and other threads that call the retrieve functions at a custom rate.
New images have always different timestamps.
