UINT bOpen 1 – open; 0 -- close
UINT nDisplayChannel the index for the display channel
UINT nDisplayRegion the area that want to dispaly
UINT nReserved reserved
Explanation:
Set the decodeing video to display (just in the current board). Put the decoding video
from the nPort in the nDecodeChannel (that is in the current board)to the
nDisplayRegion in the nDisplayChannel. There have 2 port in the decode channel, so
the nPort must be 0or 1. There have 4 display channel in the DS400xMDI, so the
nDisplayChannel must be 0,1,2 or 3
5.1.47. int SetDecoderVideoExtOutput(UINT nDecodeChannel,UINT nPort,UINT bOpen,UINT
nDisplayChannel,UINT nDisplayRegion,UINT nReserved)
Parameter:
UINT nDecodeChannel the index for the decode channel
UINT nPort the output port for the decode
UINT bOpen 1 – open; 0 -- close
UINT nDisplayChannel the index for the display channel
UINT nDisplayRegion the area that want to dispaly
UINT nFrameRate Frame rate of video output
Explanation:
This is the expand for the SetDecoderVideoOutput. It is Matrix output. It could put the
decodingdata to the other boards. The index for the nDisplayChannel is index from
the whole MDI board.
5.1.48. int SetEncoderVideoExtOutput(UINT nEncodeChannel,UINT nPort,int bOpen,UINT
nDisplayChannel,UINT nDisplayRegion,UINT nReserved);
Parameter:
UINT nEncodeChannel the index for the encode channel
UINT nPort the output port for the decode
UINT bOpen 1 – open; 0 -- close
UINT nDisplayChannel the index for the display channel
UINT nDisplayRegion the area that want to dispaly
UINT nReserved reserved
Explanation:
Set the encoding data to display output.（Matrix output）。 Put the video data from the
nPort in the nEncodeChannel to the nDisplayRegion in the nDisplayChannel. The
encode channel only support 2 port output. So the nPort must be 0 or 1.
This API is fit for combination use of DS-40xxHCI and MDI card, or DS-42xxHFVI
card. But DS-42xxHFVI card only output single channel and nPort should be 0.
