hi, our CVBS output has a obvious delay, at the beginning, it's about 0.64 seconds. then I do some alters:
(1). SwMsLink_CreateParams.numoutbuf set to 2, it was 6 before; SwMsLink_CreateParams.maxInputQueLen is 0.
(2). CaptureLink_CreateParams.numExtraBufs set to 0; CaptureLink_CreateParams.numBufsPerCh set to 2;
they were all 16 before.
After the alters, the delay is about 0.44 seconds, there is an improvement, but delay is also obvious. DVI and VGA output have no delay(the same video source)
our dvr_rdk version is 2.00.00.23， I have the code source for 4.0, so I transplant the code about DisplayLink_CreateParams.queueInISRFlag into our version, but there is no improvement.
