    What is the issue you see when you stop and start capture link ? Why are you trying to stop and start capture link ?

    Hi, 

    I want to flush buffer of capture link.

    Our application will remove video input. If user remove video input(SDI cable), VIP will capture illegal frame.

    So I need to flush all buffer when cable removed.

    When I stop and start capture link, FVID2_dequeue() cannot get any frame. I have checked  the frameList.numFrames is zero.

    Thanks

    Can you configure VIP to skip all fields when you remove input cable.Changes are below:

    /dvr_rdk/mcfw/src_bios6/links_m3vpss/capture/captureLink_tsk.c

                case CAPTURE_LINK_CMD_SKIP_ODD_FIELDS:

                   CaptureLink_drvSkipOddFields

     

    To skip all fields capture driver skip mask should be set to

     

    +                     case CAPTURE_LINK_ALL_FIELD_SKIP:

    +                    {

    +                        pChObj->frameSkipMask = 0xFFFFFFFF;

    +                        break;

    +                    }
