XVID decode compatibility problem

yupp - the search button would've lead you here: which is on page 2 of the Regards Koepi

Random access should only be messed up while using B-frames with packed bitstream turned OFF. And that's not a bug but a container issue.

OK, but why did it work with dev-api-3 and no longer with dev-api-4. I still don't use Packed Bitstream ( never used it ), and it works fine with dev-api-4 decoded by dev-api-4, and with dev-3 decoded by dev-3. Does that mean that the previous decoder ( for dev-api-3 ) contained a 'hack' in order the random access to work properly without packed bitstream ?

FFdshow in Matroska MPEG4 playback pack decodes both dev3+4 of XviD perfectly fine without packedbitstream. So I don't really know whats really wrong with ur ffdshow, maybe its old :rolleyes:

K-Dash : it isn't old ( 16/08/2003 and 28/11/2003 ), and there is no problem with decoding. It's just that a random access ( in avisynth, using either directshowsource ( and so ffdshow )) doesn't bring me to the right frame ( not always in fact, but randomly :p ) But, with dev-api-4, both ( avisource, and directshowsource ) work flawlessly.

Opps, sorry. I was quoting Alexnoe ffdshow ver not urs Manao. ffdshow 23/05/2003 <-- thats old.
