camera async frame grab (1418)

[GalacticEmperor1]

Issue №1418 opened by illume at 2019-10-14 13:15:53

src_c/camera_v4l2.c v4l2_query_buffer() commented a FIXME:

There needs to be a better way to implement non-blocking frame grabbing than only doing a get_image if query_image returns true. Many cameras will always return false, and will only respond to blocking calls.
