hi,I am using the dvsdk demos(dvsdk_demos_2_10_00_1x/dm365/encode)
as there is the previewer and the resizer device to configure before the capure device
I found follows
case 1: when the previewer is configured in sole mode (not chain with the reszier,and the resizer is not opend and configured),the captured picture has been de-interlaced,
case 2: when the resizer is configured in sole mode(not chain with the previewer,and the previewer is not opend and configured), ,the captured picture has not been de-interlaced;
case3: also,when i chain them in continous mode, the captured picture also has been de-interlaced.
But what i see in the VPFECaptureDriverUsersGuide,it says:
' In continuous mode, with interlaced scan input, only the second field of the input data is used for
capture at Resizer and is scaled up by 2x to preserve the height. So in this mode, the video is de-interlaced at the driver and hence both fields are not available.'
what i think this sentence is not typically pointed to dm365 but dm6446?
My question is: can anyone explain it and the upper threee cases? and does the previewer of dm365 do the de-interlace work? or can i be further told the difference between them?
thanks a lot
