VLC 1.1.3 transcoding high CPU usage

[nereikianieko]

I've tried transcoding live content with VLC 1.1.3 and it has extremely high CPU usage (45-60% CPU) compared to VLC 1.0.5 (15-20% CPU)

Both VLC are running with default preferences, vlc is started with telnet interface enabled:
vlc.exe -I dummy --intf="http" --http-host="127.0.0.1:8603" --extraintf="telnet" --telnet-port="8703" --telnet-password="xxx"

I'm trying transcode the same content, the same PC with CPU AMD Athlon II X4 630 running at 3Gz , Windows XP.
My transcoding line is as follows:
#transcode{vcodec=h264,venc=x264{vbv-maxrate=128,vbv-minrate=128,qcomp=0,ratetol=0.1,keyint=20}vb=128,width=320,height=240,me=umh,acodec=mp4a,ab=128,channels=2,samplerate=44100,audio-sync}

AFAIK x264 default settings have changed dramatically between VLC 1.0.5 and VLC 1.1.3 releases. So you need more parameters if you want to use same settings now.

Is there any new help or documentation for this? I'm really confused right now, because looking at the documentation, I'm not sure is it suitable for new version (1.1.x) or not...
I remember there was a page about x264 settings, but now I just cannot find it on videolan.org, using Google, in my bookmarks, anythere. Was it removed?

Helo, my english is bad. I testing VLC and MPC-HC. In both programs turned GPU ATI 3670 (xps-studio T9600) with latest 10.7 drivers (changelog hardare support VLC 1.1.1)
Here are the results:




difference in favor of homecinema, in principle, twice: (
Why?

Totally irrelevant to the thread.

MPC-HC uses DxVA and VLC DxVA2, and DxVA2 doesn't work correctly with ATI 3xxx

nereikianieko: x264 settings can be found at least from http://mewiki.project357.com/wiki/X264_Settings (I didn't check if that page is updated)
