WebFeb 2, 2016 · Keep two different tail pointers in your buffer, one for each consumer. When the producer is updating the queue, use the farthest tail pointer (the tail pointer which is lagging behind) to check if the buffer is full. Consumers can use their own tail pointers to check if the buffer is empty. WebYou may get “sequence buffer overflow” (also known as “circular buffer overflow”) errors during acquisitions, especially at high frame rates. If so, try increasing the sequence buffer size (for fast streaming of large images, much larger settings can sometimes be useful).
