    Ralph Kim
    I have two questions. 1) runOMTB source code. I was building and testing omtb_01_00_00_02 program as OMTB_User_Guide.pdf. But the result is not same as Matrix GUI(run Multimedia menu). runOMTB is executed by Matrix GUI program. I think that "./omtb_dm816xbm_a8host.xv5T <script>"...

  • Forum Post: OMX/OMTB/VFCC: Is a plain vanilla video capture and display possible without using the TVP component?

    Juan Solis
    Hello, We're trying to see if we can set up a simple video capture demo using OMTB on a DM8168 -based PROTOTYPE board (not the DDR3-EVM) using EZSDK ti-ezsdk_dm816x-evm_5_01_01_80 as a starting point. My thought is to take the dual_display_encode_decode_no_pause.oms script since it uses the VFCC...

    Juan Solis
    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...

    stegre
    Do any of the of the OMTB scripts in SDK 5.01.00.80 run without the Netra EVM daugtercard? Seems like some of them would need it (for capture input), though some shouldn't (e.g. "fread_venc_fwrite"). I guess the stand-alone OMX "decode" demo from the SDK requires it, but what...
