Is there a difference between Xvid, DivX and ffdshow for divx/xvid decoding?
Hi,
Basically, what the titles says... For decoding only of video content in XviD or DivX formats, is there a difference in picture quality between using XviD, DivX or ffdshow decoders? |

But -overall- if the iDCT match the dct of the encoder (and problems in case of mismatch are most of the time marginal) the output should be exactly the same between each decoder. Now ffdshow is a bit better in my opinion since ffdshow can apply post processing filter which help a lot to "enhance" your picture quality. So in a way ffdshow "give" a better picture quality but post processing "modify" the picture to make it different than what the video data said to output: Deblock it (there is no deblocking filter in Advanced Simple Profile so you have to do it yourselff), Sharpen it, etc. Last edited by Esurnir; 1st February 2009 at 17:30. |
