海思3516, 单摄像头接hdmi,并输出h.265文件

在CSI1接一个GC2053, CSI输入决定了下面代码里面的ViDev.

在sample目录建一个子目录, 名字无所谓

建一个Makefile

# Hisilicon Hi35xx sample Makefileinclude ../Makefile.paramSMP_SRCS := $(wildcard *.c)
TARGET := $(SMP_SRCS:%.c=%)TARGET_PATH := $(PWD)# compile linux or HuaweiLite
include $(PWD)/../$(ARM_ARCH)_$(OSTYPE).mak

新建一个c文件, 代码如下

C代码:#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <pthread.h>
#include <signal.h>

在目录下, make, 然后复制到板子上, 接上hdmi, 就可以看到图像了, 另外还会生成h.265的文件.
啥? 咋打开h265…自己百度一下…
