[FFmpeg-devel] H.264 - interlacing artifacts fix: No balanced CPU-core usage

Hi there,

sorry for this double post - i was not sure if "ffmpeg-user" list is appropriate for this question. 
referencing to the changes coming with this fix out of ffmpeg-devel list (H.264 & interlacing artifacts:
http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2008-July/050391.html) i must recognize a significant 
increase in CPU usage. 

Especially using ffmpeg (since SVN-r14496 where the fix is included) for decoding HD-live material via 
xine (ex. xineliboutput/vdr) the according processes (xine, vdr-sxfe) do not scale balanced between 
the 2 cpu-cores (2 threads). one core is at 100% now, which was not the case before the provider encoder
changes (no IDR-/I-frames anymore). So live HD-channels are jerked now :(

is there any change to avoid this, or will there be another fix adressing this problem?

thanks a lot in advance!

ps: if there must be adaptions to xine itself, i'm sorry about posting in this maillist! :o/
