[已解决]分享3516a+imx178 优化rtsp图传效果参考ljx6233535的帖子：3516a/d+imx290

mpp/sample 里面我没有找到相关资料。下面参考论坛资料，分享3516a+imx178 优化rtsp图传效果

[color=Red]具体步骤： 1 put directory hp-ipc into sdk.../mpp/sample/ 2 cd ipc_imx178 3 make [/color]

使用方法： 1、参照自己的Sensor的接口方式，修改hp_vi.c 中 static HI_VOID viAttrInit(const IPC_VEDIO_S* pstIpcVedio,VI_ATTR_S **pstViAttr)函数中的配置参数（接口，时序，掩码等等），注意，不用修改图像格式和帧率，这个是上层自动传下来的。 2、参照hp_ipc.c中main函数，修改自己想要的大小和帧率，码流数量。 int main() { FARMAT_S stFmt_a[3] = { {PIC_HD720,30}, {PIC_VGA,30}, {PIC_QVGA,30} }; IPC_Init(3,stFmt_a);//3表示几路，stFmt_a定义每一路的大小和帧率，注意，主码流必须在最前面。 getchar(); getchar(); IPC_exit(); return 0; } 3、把hp_ipc文件夹放到mpp/sample/下，make就可以了（注意：把sample/Makefile.param中SENSOR_LIBS修改成你Sensor的库）。 4、把hp_ipc挂载到板子上跑起来~~

5 PC上使用vlc rtsp://192.168.1.32:554/stream_chn0.h264 打开码流是，缓冲区设置为300ms,不然延迟比较大。这是个简单的图传，所以传1080p比较勉强，不过我测试传720p及以下的分辨率效果还是可以的，能满足调试需要。

[color=Red]Windows VLC Setting: Media ----> Open Network Stream ---> Show more details ---> Caching 1000ms(default) change to 300ms or 180ms rtsp://192.168.1.32:554/stream_chn0.h264 Delay around 0.5s [/color]

VLC for mobile： Download VLC for mobile ---> Network Stream ---> Open Network Stream rtsp://192.168.1.32:554/stream_chn0.h264

正在考虑解决的： 1 client needs to type password 2 It will support multiple clients.

由于系统还处在测试阶段，不够完善，实际项目还在研究学习中，要根据实际情况进一步优化，以达到更好的性能。

楼主，请问一下我用IMX122，去哪里查询Sensor的接口方式，来修改static HI_VOID viAttrInit配置参数（接口，时序，掩码等等）

楼主，你好，如果是多通道怎么实现？我把你主函数里的改成IPC_Init(2,stFmt_a);用VLC抓取到的视频流是错误的。
