hi3518e liteos5.2平台利用尚云API接口实现p2pmode 推视频流和音频流

1.在I:\hi3518ev200\liteos\Hi3518E_SDK_V5.0.5.0\mpp\sample\Makefile.param添加尚云的库文件libliteos_5.0.5.1.a，该推流库文件包含了一系列api函数，eg:

Common:
• PPCS_Initialize, PPCS_DeInitialize
• PPCS_NetworkDetect
• PPCS_NetworkDetectByServer
• PPCS_GetAPIVersion
• PPCS_Share_Bandwidth
• PPCS_Get_ServerIP
• Device:
• PPCS_Listen
• PPCS_Listen_Break
• PPCS_LoginStatus_Check
• Client:
• PPCS_Connect
• PPCS_ConnectByServer
• PPCS_Connect_Break
• Session:
• PPCS_Check
• PPCS_Close
• Read / Write data
• PPCS_Read
• PPCS_Write
• Check Buffer size

• PPCS_Check_Buffer

  SENSOR_LIBS += $(REL_LIB)/libliteos_5.0.5.1.a

2.在I:\hi3518ev200\liteos\Hi3518E_SDK_V5.0.5.0\mpp\lib添加尚云的接口库文件libliteos_5.0.5.1.a

3.添加尚云API接口的头文件

把C:\Users\Administrator\Desktop\尚云P2P\p2p\Release_PPCS_2.4.0_客户端&设备端\Include\PPCS目录下的3个文件添加到目录下面I:\hi3518ev200\liteos\Hi3518E_SDK_V5.0.5.0\mpp\include

PPCS_API.h

PPCS_Error.h

PPCS_Type.h

4.在具体应用venc目录下面的其中2个文件里面添加尚云api接口，实现p2p推流

5.编译 make root@dreams:~/ipc/hi3518ev200/liteos/Hi3518E_SDK_V5.0.5.0/mpp/sample# 

也可以在具体的应用下面编译:

譬如 make root@dreams:~/ipc/hi3518ev200/liteos/Hi3518E_SDK_V5.0.5.0/mpp/sample/venc/
