Peter,
I applied Janne's patch for skiploopfilter, but I was actually running
with a directshow patch and using coreavc rather than the h264 decoder.
[Ticket #3053: Adds support for DirectShow filters for the frontend]
Janne,
Dual core support for h264 in ffmpeg is really really great news !
I think we still need access to any tweeks to reduce cpu requirements
though, such as the skiploopfilter option. I am running my frontend with
coreavc, and it uses 60-80% of both cores of an core2duo e4300 to decode
BBC HD. its MBAFF and seems to really torture the processor ;-). Oh, and
a fix for the AC3 bug would be cool too :-) (Only joking )
best regards,
John
