The capture_async test was written to run for a fixed 5 second duration. Modify the test such that it runs until it has captured 30 frames, or a 10 second time out occurs. Running the capture_async test on an ARM64 platform using VIVID captures 30 frames in 6.15 seconds. There may be scope to optimise this speed by changing the format on the capture device.
