Dear IPP:
I install IPP 5.3.3.082 , and download the sample code: w_ipp-samples_p_5.3.095.zip
I read the document "umc-manual.pdf" , page 176 about example of UMC base classes usage, it can compile successful.
Then I modify the source code , let it can decoder the MPeg4, it work fine again.
But when I try to implement the source code about Mpeg4 encoder, I get an error like : "error LNK2019: unresolved external symbol _errno....... when reference about function: __libm_error_support..."
Below is my source code :
//////////////////////////////////////////////// begin of source code ////////////////////////////////////////////////////////////////////////////////////////
#include "umc_mpeg4_video_encoder.h"
using namespace UMC;
int main(int argc, char* argv[])
{
VideoEncoderParams params ;
MPEG4VideoEncoder encoder; // mark this line will be compile successful, unmark will get compile error
//// Set encoder params
params.info.clip_info.width = 720;
params.info.clip_info.height = 288;
params.info.bitrate = 1000000;
params.info.framerate = 25;
params.numEncodedFrames = 2147483647; // all frames : INT_MAX,2147483647
params.numThreads = 0;
return 0;
}
////////////////////////////////////////////////end of source code ////////////////////////////////////////////////////////////////////////////////////////
I use MSVC 7.1 to compile the source code. When I mark this line "MPEG4VideoEncoder encoder;
" , It will compile successful.Could anyone help me resolve this problem, thank you very much.
