DM385通过DVO2(VOUT0)输出PAL视频问题

如题所示：DM385通过DVO2(VOUT0)输出PAL视频问题请教

首先使用的是ipnc_rdk 3.8版本，采用 ENC->A8->DEC usecase，配置输出HDMI和PAL模拟视频均正常

现在需要使用DVO2输出PAL模拟视频，分辨率为720*576 

更改如下：

1、在ipnc_rdk\ipnc_mcfw\demos\mcfw_api_demos\multich_usecase\Ti_mcfw_ipnc_main.c文件中

 //Original Code 

//vdisParams.deviceParams[VDIS_DEV_DVO2].resolution = VSYS_STD_720P_60;

//Modified Code

vdisParams.deviceParams[VDIS_DEV_DVO2].resolution = VSYS_STD_PAL;

2、在ti_vdis.c 中函数Vdis_params_init

 //Original Code 

pContext->deviceParams[i].resolution = VSYS_STD_720P_60;

width = 1280;
height = 720;

if(i == VDIS_DEV_SD)
{
     pContext->deviceParams[i].resolution = VSYS_STD_PAL;
     width = 720;
     height = 576;
}

//Modified Code

if((i == VDIS_DEV_SD)||(i == VDIS_DEV_DVO2))
{
pContext->deviceParams[i].resolution = VSYS_STD_PAL;
width = 720;
height = 576;
}

3、在multich_encode_decode.c中配置

// gVdisModuleContext.displayId[VDIS_DEV_SD] = SYSTEM_LINK_ID_DISPLAY_2;
// gVdisModuleContext.displayId[VDIS_DEV_HDMI] = SYSTEM_LINK_ID_DISPLAY_0;
gVdisModuleContext.displayId[VDIS_DEV_DVO2] = SYSTEM_LINK_ID_DISPLAY_1;

……

/* display link params */
MULTICH_INIT_STRUCT(DisplayLink_CreateParams,displayPrm_SD);
displayPrm_SD.inQueParams[0].prevLinkId = gDupId1;//gSwOsdId;//gDupId1;
displayPrm_SD.inQueParams[0].prevLinkQueId = 0;

// HDMI DISPLAY //displayPrm_SD.displayRes = gVdisModuleContext.vdisConfig.deviceParams[VDIS_DEV_HDMI].resolution;
//displayPrm_SD.displayId = DISPLAY_LINK_DISPLAY_SC1;

//PAL DISPLAY
// displayPrm_SD.displayRes = gVdisModuleContext.vdisConfig.deviceParams[VDIS_DEV_SD].resolution;
// displayPrm_SD.displayId = DISPLAY_LINK_DISPLAY_SD;

//LCD DISPLAY
displayPrm_SD.displayRes = gVdisModuleContext.vdisConfig.deviceParams[VDIS_DEV_DVO2].resolution;
displayPrm_SD.displayId = DISPLAY_LINK_DISPLAY_BP1;

这样配置完后，程序报错：

参考论坛上的

发现DVO2都是与HDMI或者HDCOMP绑定使用，

请问：1、DVO2能否独立输出模拟视频？

            2、我以上配置对吗？还有哪些配置漏掉了？

谢谢

Chris Meng：

你好，

DVO2可以独立与HDMI输出数字信号，DVO2没有自带video ADC，不能直接输出模拟视频。

我手上有一份资料是基于DVR RDK4.0上去掉DVO2和HDMI时序绑定的修改，你参考看看是否有帮助。

非常感谢 Chris Meng 

    首先纠正一下问题，我不是直接输出模拟视频，是要输出数字视频，分辨率为720*576 ；

需要DVO2独立输出；

  我先看看你给的参考文档，谢谢

孟工 你好：

参照你提供的文档，主要是TI814X 解绑DVO2的解释，参照该文档，我修改了以下几个地方；

1、在/mcfw/src_bios6/links_m3vpss/system/system_dctrl.c中改为#if defined(TI_8107_BUILD)/* Display Controller Configuration *//* To tie DVO2 and HDCOMP together refer following Mesh */Vps_DcConfig gSystem_dctrlTriDisplayConfig = { VPS_DC_USERSETTINGS, /* Use Case */ /* Edge information */ { {VPS_DC_BP0_INPUT_PATH, VPS_DC_VCOMP_MUX}, {VPS_DC_VCOMP_MUX, VPS_DC_VCOMP}, {VPS_DC_CIG_NON_CONSTRAINED_OUTPUT, VPS_DC_HDMI_BLEND},

{VPS_DC_GRPX0_INPUT_PATH, VPS_DC_HDMI_BLEND}, {VPS_DC_GRPX1_INPUT_PATH, VPS_DC_DVO2_BLEND},

{VPS_DC_MAIN_INPUT_PATH, VPS_DC_VCOMP}, {VPS_DC_AUX_INPUT_PATH, VPS_DC_VCOMP_MUX}, }, 10, /* VENC information */ { /* Mode information */ { {VPS_DC_VENC_HDMI, {FVID2_STD_1080P_60} } , /* 1080p30 is mode * is overwritten * later inside * System_displayCtrlInit */ {VPS_DC_VENC_HDCOMP, {FVID2_STD_1080P_60} }, /* 1080p30 is mode * is overwritten * later inside * System_displayCtrlInit */

2、在ipnc_rdk/ipnc_mcfw/mcfw/src_bios6/links_m3vpss/system/system_dctrl_modeInfo.c中

#if defined(TI_8107_BUILD) if(System_getVencMode(pPrm->deviceParams[SYSTEM_DC_VENC_HDMI].resolution) != FVID2_STD_CUSTOM) { gSystem_objVpss.displayCtrlCfg.vencInfo.modeInfo[0].mInfo.standard = System_getVencMode(pPrm->deviceParams[SYSTEM_DC_VENC_HDMI].resolution); } else { retVal = System_setVencModeInfo(0, pPrm->deviceParams[SYSTEM_DC_VENC_HDMI].resolution); UTILS_assert(0 == retVal); }

3、在ti_mcfw_ipnc_main.c中

 vdisParams.deviceParams[VDIS_DEV_DVO2].resolution = VSYS_STD_PAL;

4、在ti_vids文件Void Vdis_params_init(VDIS_PARAMS_S * pContext)函数中

//  pContext->tiedDevicesMask = VDIS_VENC_HDMI | VDIS_VENC_DVO2;

pContext->tiedDevicesMask = 0;

pContext->enableConfigExtVideoEncoder = TRUE;

5、在 ipnc_mcfw/mcfw/src_linux/mcfw_api/usecases/multich_encode_decode.c中设置

// gVdisModuleContext.displayId[VDIS_DEV_SD] = SYSTEM_LINK_ID_DISPLAY_2;// gVdisModuleContext.displayId[VDIS_DEV_HDMI] = SYSTEM_LINK_ID_DISPLAY_0; gVdisModuleContext.displayId[VDIS_DEV_DVO2] = SYSTEM_LINK_ID_DISPLAY_1;

……

// HDMI DISPLAY //displayPrm_SD.displayRes = gVdisModuleContext.vdisConfig.deviceParams[VDIS_DEV_HDMI].resolution; //displayPrm_SD.displayId = DISPLAY_LINK_DISPLAY_SC1;

//PAL DISPLAY// displayPrm_SD.displayRes = gVdisModuleContext.vdisConfig.deviceParams[VDIS_DEV_SD].resolution;// displayPrm_SD.displayId = DISPLAY_LINK_DISPLAY_SD;

//LCD DISPLAY displayPrm_SD.displayRes = gVdisModuleContext.vdisConfig.deviceParams[VDIS_DEV_DVO2].resolution; displayPrm_SD.displayId = DISPLAY_LINK_DISPLAY_BP1;

以上修改后，程序报错：

另外我测试HS/VS/CLK都有信号，测试值为74.25M，30HZ

理论上VSYS_STD_PAL应该是27M才对是吧

以上配置都对吗？还是哪里没有配置？请指点指点，谢谢

你好，

一般的video dac都不需要activeid的信号，你能否确认一下? 如果不需要该信号，就不需要配置这个pinmux。

另，请查看这个硬件是否有做其他用途导致你修改pinmux后对系统产生影响？
