pContext->deviceParams[VDIS_DEV_DVO2].outputInfo.vencNodeNum = VDIS_VENC_DVO2;
pContext->deviceParams[VDIS_DEV_DVO2].outputInfo.aFmt = VDIS_A_OUTPUT_COMPOSITE;
pContext->deviceParams[VDIS_DEV_DVO2].outputInfo.dvoFidPolarity = VDIS_POLARITY_ACT_HIGH;
pContext->deviceParams[VDIS_DEV_DVO2].outputInfo.dvoVsPolarity = VDIS_POLARITY_ACT_HIGH;
pContext->deviceParams[VDIS_DEV_DVO2].outputInfo.dvoHsPolarity = VDIS_POLARITY_ACT_HIGH;
pContext->deviceParams[VDIS_DEV_DVO2].outputInfo.dvoActVidPolarity = VDIS_POLARITY_ACT_HIGH;

    pContext->deviceParams[VDIS_DEV_DVO2].outputInfo.dvoFmt = VDIS_DVOFMT_DOUBLECHAN;
    pContext->deviceParams[VDIS_DEV_DVO2].outputInfo.dataFormat = SYSTEM_DF_YUV422SP_UV;

    Means two channels used in your application,one for luminance.other for chroma.

    Dataformat of 9022's output is YUV422SP_UV.

    so how should  i change that parameters ?use the default value the color is green .but when i change that value of pContext->deviceParams[VDIS_DEV_DVO2].outputInfo.dvoFmt = VDIS_DVOFMT_TRIPLECHAN_EMBSYNC

    that color will be changed.
