Not synced, this change is not relevant.

So  we have  deva-pi-4 in  sync  with cvs_head  since 2  weeks. As  pete
mentioned  in another  email,  dev-api-4  will be  merged  back soon  to
cvs_head. It would be good that Windows devs start updating vfw (the one
in the xvidcore module, not the vfw module anymore). 

I'd say dev-api-4 works fine on GNU/Linux (achieved 3 complete DVDs rips
using constant quant) but i  have some questions before i start updating
the  transcode  frontend  and  help elcabesa  maintaining  his  mencoder
module. 

The problem  is completly AVI  related. In the  hope to avoid  A/V syncs
i've tried  to use Packed  bitstream, but all  the AVIs i  created using
this packed  option, were completely  unusable with WMP. The  stream was
right, but  basically the  problem was  that i was  pushing data  to the
muxer only  when xvidcore returned me  data. So i  think classic parsers
(vfw, videolan client and mplayer <= 0.90rc3 iirc) were complaining "not
coded vops" every 2 frames. 

How do you solved that with the new API in the VFW frontend ? 

NB: this was  not a problem in cvs_head because  in those cases xvidcore
    was returning NVOPS that we had just to push to the muxer.
