Hello josh,
Apologies, but none of the current Astra cameras support 60 fps. This is a hardware limitation.
Sound reasonable, but why do C-function astra_imagestream_get_modes_result and C++ member ImageStream::available_modes() return 320x240 60fps mode for depth stream when using with Astra Pro? If hardware doesn’t support some mode, it is obvious that this mode cannot be reported as available. In other case astra_imagestream_get_modes_result and ImageStream::available_modes() are totally useless,
