In the if ((hitFV) && (prodCount == consCount)) block of UVC app thread entry you can print the producer count to see how many buffers were sent per frame , and also where the header for the last buffer is added you can print the produced_buffer.count to find the number of bytes in the last buffer.
But are you sure you dont get any commit buffer failures ??
Thanks for your reply.
I bought a PCI to USB3.0 host interface card, because my desktop PC does not have USB3.0.
I modified AN75779 souce code and build then dowload img to target board.
When I run virtualDub to check image, frame rate was 15.00fps and output size was 640x480.
At this time, I can see the buffer failures message through UART.
So, I modify source code for sensor to set VGA/15fps.
And try again, there was one or two buffer failures message before starting frame counting
and frame count value was increasing.
By the way, my board has a problem. Almost UART port is not work, sometimes is work.
so I just sent a email to firstname.lastname@example.org for asking after serive.
