Thanks, Brijesh Jadav From:[email protected] [mailto:[email protected]] On Behalf OfOndrej Pindroch Sent: Thursday, May 21, 2009 5:48 PM To: davinci-linux-open-source Subject: How to improve image latency Hi I have an aplication which is useing CCDC PREVIEWER and V4L2 for output. There is one buffer between CCDC and PREVIEWER (exactly 3 buffers) and for output it is used buffer from V4L2. For now I have latency 160 - 200ms. I have made some mistakes and loosing frames (hudge bunche of errors). Than I have had latency less than 100ms. I have alredy measured time needed for capture and proccessing. It was 5-7ms. >From capture to get frame buffer from V4L2 it take almost 40ms (25fps for PAL) Have you any idea where I get this 120ms of additional latency. Frame rate of sensor is almost 60fps Thanks Ondrej Pindroch SoftHard Technology ltd.
