Mac Compilation

#cmake arch

SET(CMAKE_C_COMPILER /usr/bin/clang)
SET(CMAKE_CXX_COMPILER /usr/bin/clang++)

#Compiler settings

set(CMAKE_C_STANDARD 11)
set(CMAKE_C_STANDARD_REQUIRED ON)

Demo Compilation

demo/metapushstream8 and demo/metaplayer8
Streaming demo metapushstream8

Open the file CMakeLists.txt in Qt. On macOS, you need to use CMake to compile.

MAC/iOS Video Encoding and Decoding

Video Encoding

    if(videoInfo->videoEncHwType==0){//software encoding
 
	    if (vcodec == Yang_VED_H264){
#if Yang_Enable_Openh264
	        return new YangOpenH264Encoder();
#else
	        return  new YangH264EncoderSoft();
#endif
        }else if (vcodec == Yang_VED_H265){
	        return new YangH265EncoderSoft();
       }
    }else{//hardware encoding
        //videoToolBox
        return new YangVideoEncoderMac();
 
    }

Video Decoding

   if(videoInfo->videoDecHwType==0){//software decoding
#if	Yang_Enable_H264Decoder
        return new YangH264DecoderSoft();
#else
        return new YangVideoDecoderFfmpeg(videoInfo,vcodec);
#endif
   }else{//hardware decoding
        return new YangVideoDecoderMac();
   }
