VSYNC or Vertical Synchronization, is a signal that is used to signify when the receiver of a video stream should...

  • Forum Post: Re: VPort Access DM6446

    Bernie Thompson TI
    Unfortunately there is no driver or chip support library type software for the C64x+ on the DM6446, as shown in the datasheet memory map most peripherals are considered reserved to the C64x+ anyway, thus the physical connection to the peripheral from the C64x+ is not validated or tested and we cannot...

    Marcus Cooksey Assuming you configure the video decoder outside the scope of OMX/OMTB then it should be possible to perform capture without the tvp and thus you can remove the tvp comment from the script. Thanks for the reply Marcus. I went ahead and tried it and the script runs without errors...
