[FFmpeg-user] Need some help for DNXHD decode

[Chao Guo]

Hi everyone

 

Who can tell me what's the difference between ff_simple_idct_put_mmx and
ff_simple_idct_put ? I compared the results they output. It's really
different. The former was nestled in X86/simple_idct_mmx.c but it's written
in assembly language, I cannot read. If who can send me a translated version
in cpp or c, I will appreciate very much. Or just tell me what's the
different with the algorithm? 

 

Cheers

Edward
