hi all

 1.           I want to know whether the SDVENC  AND HDVENC component  are avalible in the EZSDK  ti-ezsdk_dm816x-evm_5_02_01_59 ?

2.            how many means to change the chains between graphics and display

                                  1>     operate /sys/devices/platform/vpss/graphicsX/node

                                   2>       in source codes by calling OpenMax API  to connect componets

3.             by default       QT GUI is output  from on-chip hdmi 

                                        I want to view QT GUI from SD-COMP interface

                                        I added "export QWS_DISPLAY=LinuxFb:/dev/fb2" in the shell environment

                                       then run demo  ./usr/bin/qtopia/examples/richtext/calendar/calendar -qws -geometry 320x200+50+20

                                       but  nothing on the monitor but NO INPUT SIGNAL

                                      why ?

4.             when running the OMTB demo  I changed "omx setp 0 vfdc OMX_TI_IndexParamVFDCDriverInstId nDrvInstID 0"  to "omx setp 0 vfdc                      

                           OMX_TI_IndexParamVFDCDriverInstId nDrvInstID 2" in the decode_scale_display.oms file  in order to view from SD-DAC interface

                           refered /home/user/ti-ezsdk_dm816x-evm_5_02_01_59/component-sources/omx_05_02_00_15/OMX_05_02_00_15_UserGuide.pdf   21st page

5.               any other way to get image | video from SD - DAC or HD-DAC

 

 Thanks in advance for any help!

    Jim,

    You can see video in HD-DAC o/p. in the decode_display ilclient exmaple, we set the display parameters. replacing OMX_VIDEO_DISPLAY_ID_HD0 by OMX_VIDEO_DISPLAY_ID_HD1 would give o/p on HDDAC component o/p. by default fb0 is for HDMI and fb1 is for HDDAC.
