8 CHANGING THE VIDEO DEVICE

CONFIGURATION

Changes to the SDI video device configuration can be made using

NvAPI_VIO_SetConfig() and XNVCTRLSetAttribute() as outlined in the section

entitled Configuring the Video Device. Some configuration parameters may be changed

during video transfers while for other changes, video output must first be stopped with

OpenGL resources released before the new configuration parameters can take affect.

Table 8-1 shows those parameters that maybe changed during video transfers and those

that cannot be changed during video transfers.
