[FFmpeg-devel] H.264 - interlacing artifacts fix: No balanced CPU-core usage
Mon Aug 11 13:07:21 CEST 2008
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/
