cam: Print timestamp of captured buffers
Print the timestamp of the captured buffer in addition to the frame rate, as this is more precise information that can help debugging issue. The log changes from Using camera \_SB_.PCI0.XHC_.RHUB.HS05-5:1.0-0bda:58f4 Capture until user interrupts by SIGINT fps: 0.00 stream0 seq: 000000 bytesused: 169968 fps: 28.57 stream0 seq: 000002 bytesused: 170352 fps: 31.25 stream0 seq: 000003 bytesused: 170428 fps: 32.26 stream0 seq: 000004 bytesused: 170672 fps: 27.78 stream0 seq: 000005 bytesused: 170568 to Using camera \_SB_.PCI0.XHC_.RHUB.HS05-5:1.0-0bda:58f4 Capture until user interrupts by SIGINT 93473.942525 (0.00 fps) stream0 seq: 000000 bytesused: 183940 93474.006528 (15.62 fps) stream0 seq: 000002 bytesused: 183512 93474.038525 (31.25 fps) stream0 seq: 000003 bytesused: 183760 93474.074530 (27.77 fps) stream0 seq: 000004 bytesused: 182704 93474.106581 (31.20 fps) stream0 seq: 000005 bytesused: 182768 While at it, compute the frame rate on the buffer timestamps instead of sampling the clock in the request completion handler.
