有小伙伴说, 直接跑官方的代码跑不起来, 这里以vio代码为例, 说说怎么从源码编译海思的应用.
首先环境是单摄GC2053, 接CSI1, 如下图:
在sdk里面找到
hi3516sdk/smp/a7_linux/mpp/sample/Makefile.param
修改摄像头为你的摄像头型号, 比如GC2053
SENSOR0_TYPE ?= GALAXYCORE_GC2053_MIPI_2M_30FPS_10BIT SENSOR1_TYPE ?= GALAXYCORE_GC2053_MIPI_2M_30FPS_10BIT修改
hi3516sdk/smp/a7_linux/mpp/sample/common/sample_comm_vi.c
文件, 修改下面的变量值
/***************************************************************************** * function : init mipi *****************************************************************************/ HI_S32 SAMPLE_COMM_VI_StartMIPI(SAMPLE_VI_CONFIG_S *pstViConfig) { HI_S32 s32Ret = HI_SUCCESS; lane_divide_mode_t lane_divide_mode = LANE_DIVIDE_MODE_0; if (!pstViConfig) { SAMPLE_PRT(“%s: null ptr\n”, __FUNCTION__); return HI_FAILURE; } // 加入这一行 lane_divide_mode = LANE_DIVIDE_MODE_1; SAMPLE_PRT(“lane_divide_mode:%d \n”, lane_divide_mode); // lane_divide_mode = SAMPLE_COMM_VI_GetMipiLaneDivideMode(pstViConfig); s32Ret = SAMPLE_COMM_VI_SetMipiHsMode(lane_divide_mode); if (HI_SUCCESS != s32Ret) {<
在sample文件夹中建一个子文件夹, 名字无所谓, 然后建一个c文件

在同一个文件夹下面加入Makefile编译文件
# Hisilicon Hi35xx sample Makefile include ../Makefile.param SMP_SRCS := $(wildcard *.c) TARGET := $(SMP_SRCS:%.c=%) TARGET_PATH := $(PWD) # compile linux or HuaweiLite include $(PWD)/../$(ARM_ARCH)_$(OSTYPE).mak然后就make一下, 把生成的可执行文件复制到你板子上就可以跑起来了, 同时会在同一个目录生成h.265的码流.
串口看到的log应该差不多这样:
