  • Hello Munesha,

    I am assuming you want to use PC to send video streams.

    For receiving video inputs you can use null source link no. of channels set to 3. The VSDK has example use-case with TCP/IP on Null source link. You can refer to it @vision_sdk\examples\tda2xx\src\usecases\network_rx_tx\chains_networkRxDecDisplay.c

    • This use-case is configured for single channel receive only. You need to make below modifications to receive 3 channels.

    1. In current configuration done through NullSrcLink_CreateParams_Init() function (called from use-case), no. of channels is set to 1 (pPrm->outQueInfo.numCh = NULL_SRC_LINK_NUM_CHANNELS_DEFAULT)
    2. You need to override this in your use-case. Change below in file chains_networkRxDecDisplay.c

    ChainsCommon_SetNetworkRxPrms(

               &pUcObj->NullSourcePrm,

               &pUcObj->DecodePrm,

               pObj->captureOutWidth,

               pObj->captureOutHeight,

               1, <--change this to 3

               30

           );

    • You can use network_tx tools present in network_tools for sending streams from PC.

    Let me know if any issues.

    Hello MUNESHA,

    Sorry for late reply, was on vacation last week.

    What command are you using on PC? Are you inputting three video files?

    Please share output of "p"(statistics) once you run this use-case.
