EasyAVFilter代码示例之将摄像机RTSP流转成RTMP推流输出

以下是一套完整的RTSP流转RTMP推流功能的开发源码，就简简单单几行代码，就可以完成原来ffmpeg很复杂的调用流程，而且还可以集成在自己的应用程序中调用，不需要再单独一个ffmpeg的进程来调用，方法很简单：

cpp 复制代码

#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include "EasyAVFilterAPI.h"

#ifdef _WIN32
#pragma comment(lib,"EasyAVFilter.lib")
#endif

Easy_Handle fRTSPHandle = 0;			
int Easy_APICALL __AVFilterCallBack(void* userPtr, EASY_AV_FILTER_STATE_T status, int progress, int errCode, const char *errMsg)
{
	//各种状态的回调，例如拉流状态/推流状态/转码状态/媒体信息
	return 0;
}

int main(int argc, char** argv)
{
	// 创建EasyAVFilter实例
	Easy_Handle avFilterHandle = NULL;
	EasyAVFilter_Create(&avFilterHandle);

	// 信息回调
	EasyAVFilter_SetCallback(avFilterHandle,__AVFilterCallBack,0);

	// 将本地视频文件转成格式化的MP4或者HLS提供点播，参考命令：./ffmpeg.exe -re -rtsp_transport tcp -i rtsp://admin:[email protected]:554/ch1/main/av_stream -vcodec copy -acodec aac -ac 2 -strict -2 -f flv rtmp://172.81.216.155:3519/live/IbMkUXeVR?sign=SxMk8X6VRz
	EasyAVFilter_AddInput(avFilterHandle, "rtsp://admin:[email protected]:554/ch1/main/av_stream", 1);
	EasyAVFilter_AddFilter(avFilterHandle, "-vcodec copy -acodec aac -ac 2 -strict -2");
	EasyAVFilter_AddFilter(avFilterHandle, "-f flv");
	EasyAVFilter_SetOutput(avFilterHandle, "rtmp://172.81.216.155:3519/live/IbMkUXeVR?sign=SxMk8X6VRz", 0);//H.265 support

	// 输出再次验证
	char filterCommand[256] = { 0 };
	EasyAVFilter_GetFilters(avFilterHandle, filterCommand);
	printf("command: %s\n", filterCommand);

	getchar();
	EasyAVFilter_Start(avFilterHandle, 1, 8, 10);//注意，文件转码不需要循环读取，第二个参数从1改成0

	getchar();
	// 停止流程，回收EasyAVFilter对象
	EasyAVFilter_Stop(avFilterHandle);
	EasyAVFilter_Release(&avFilterHandle);

	return 0;
}
