USB 3.1 cameras with Fresco driver limited to <6 MB
KB Number: 10291
This article discusses the limit on image size when using USB 3.1 cameras and the Fresco driver.
For USB 3.1 users with a Fresco card and driver, the Fresco driver uses a ring buffer to store images coming from the the camera. The buffer is limited to 60 MB by default. FlyCapture uses 10 image buffers to store images per default. This results in a maximum image size of 60 MB/10 = 6 MB.
We recommend using the PGRxhci driver, which does not have this limitation.
Alternative workarounds include one of the following:
To determine image size:
For example, a 1280 x 960 RGB image would be 3.7 MB.
Use the Custom Video Mode tab in FlyCap2 to adjust the camera's pixel format and resolution.
To increase the ring buffer size:
3. The default size is 48 pages. Change this to 256 pages. The configured value must be a multiple of 8 to a maximum of 256 pages.
