测试test_mpi_vo.cpp案例遇到drm_output_create not found enough vo interface 8000
本帖最后由 xhm 于 2024-7-18 16:28 编辑有两个Video Port1、Video Port3可以使用：

在test_mpi_vo.cpp中作如下设置：VoDev=3，stVoPubAttr.enIntfType = VO_INTF_DP，相当于调用Video Port3设备，类型为DP。
/* Bind Layer */
VoLayer = RK356X_VOP_LAYER_ESMART_3; //3
VoDev = RK356X_VO_DEV_HD3; //3
if (ctx->bDoubleScreen) {
VoLayer_second = 3; // RK356X_VOP_LAYER_ESMART_0
VoDev_second = 3; //RK356X_VOP_LAYER_ESMART_1
RK_MPI_VO_BindLayer(VoLayer_second, VoDev_second, VO_LAYER_MODE_GRAPHIC);
}
Sample_Print("1.2..................................");
RK_MPI_VO_BindLayer(VoLayer, VoDev, VO_LAYER_MODE_GRAPHIC);
if (ctx->bHomologous) {
stVoPubAttr.enIntfType = VO_INTF_HDMI | VO_INTF_EDP;
stVoPubAttr.u32BgColor = 0x000000;
} else {
stVoPubAttr.enIntfType = VO_INTF_DP;//VO_INTF_HDMI
}
编译执行后LOG如下：报错drm_output_create not found enough vo interface 8000

备注：Video Port1可以正常使用，通过HDMI类型调用，正常出图象。Video Port3会出错，这是为什么呢？
Hi:
请问原因是什么？问题解决了吗？
