linking errors when using DV codec

shyaki — Mon, 28 May 2007 13:35:14 GMT

Hi,

I tried to use the DV25 encoder, but I got the following linkage error:

dv_enc.lib(umc_dv25_video_encoder.obj) : error LNK2019: unresolved external symbol "public: __thiscall UMC::DVVideoEncoder::DVVideoEncoder(void)" (??0DVVideoEncoder@UMC@@QAE@XZ) referenced in function "public: __thiscall UMC::DV25VideoEncoder::DV25VideoEncoder(void)" (??0DV25VideoEncoder@UMC@@QAE@XZ)

I have linked dv25_enc.lib

I can use the MPEG2 encoder correctly.

Could you please give me some clue how to fix it? I attach my code in the end.

Thank you very much.

using

{

VideoEncoder *pCodec;

//pCodec = createMPEG2VideoEncoder();

pCodec = createDV25VideoEncoder();

if (pCodec)

{

delete pCodec;

pCodec = NULL;

}

return 0;

}

I forgot to post the definition of createDV25VideoEncoder():

VideoEncoder

*createDV25VideoEncoder()

{

VideoEncoder* ptr = new DV25VideoEncoder;

return ptr;

}

I was so suprised when I found out the reason.The DV25 codec is not finished!. I hope the intel guys will get it done soon.

Hi, DV25 codec is finished, it depends on dv_enc.lib, so you need to add this lib in your linker options
