-
运行还需要dll(运行库)
-
参数结构体初始化
NET_DVR_DEVICEINFO_V40 devinfoSDK报参数为nullptr错误. 可用NET_DVR_DEVICEINFO_V40 devinfo ={}初始化 -
需要包含 windows api

解决
它不是完全的裸视频流,有封装格式, 包括音频, ffmpeg avformat_open_input 是可以打开的! (擦, 不早试一下..)
avformat_find_stream_info 也可以分析出流索引..
源文件 测试方法: main_view_video_file
so ..
所以必须, 从内存喂数据了…
unsigned char* _iobuffer = (unsigned char*)av_malloc(40690);//要足够大
AVIOContext* avio = avio_alloc_context(_iobuffer , 40690 , 0 , this, fill_buffer,nullptr,nullptr);
assert( avio != NULL);
avFormat->pb = avio;
if ( ( avformat_open_input(&avFormat, nullptr,nullptr, nullptr) ) != 0) {
qDebug()<<"Could not open input .";
return ;
}
...
错误
Java 海康Linux SDK 登陆29 错误码
总是 login fail 29(Device operation failed., 错误码也没参考价值. 没头绪..
解决
使用命令 objdump 看下依赖的库;
$ objdump -x java -jar testm.jar /home/jk-nyy/CH-HCNetSDKV6.1.4.17_build20200331_Linux64/lib/libhcnetsdk.so
