Hello everyone:
I am using dm368 to do some IPNC develop.The DVSDK Version is 4_00_00_22.
The camera can provide 1080P30 and 720P60. It works well at 1080P30. But if I set to capture at 720P60, It comes out at 30fps. I know there is a conversion because the
HALF-RATE setting. In the dmai\linux\dm365\capture.c, it is
if (attrs->videoStd == VideoStd_720P_30)
{
halfRateCapture = TRUE;
attrs->videoStd = VideoStd_720P_60;
}
And It will use ioctl VIDIOC_S_PARM to set capture parameters to reduce frames to half.
if I set attrs->videoStd = VideoStd_720P_30, It use half-rate to capture at 30fps.
If I set attrs->videoStd = VideoStd_720P_60. It capture nothing. Why ?
Do I need to change dm365 default resizer of previewer settings?
Can somebody help me. Thanks a lot .
