There seems to be some weird bug with the resizing.
Resizing 640x480 video to fullscreen 1280x1024 (with black bars) results in 100% CPU usage. If I just resize the window by a random amount I either get no increase in CPU usage or sometimes I hit a spot where the CPU usage goes through the roof again (100% or sometimes a smaller amount). No correlation between output frame size and CPU usage, eg. find a spot where 100% CPU usage occurs and then enlarge the window a little and the CPU usage drops to normal levels.
If I force YV12 output colorspace from ffdshow the CPU usage stays normal during any resizing. When no output colorspace is forced, YUY2 is selected and the above mentioned rise in CPU usage occurs. With RGB32 forced there is smaller rise (in fullscreen, didn't try resizing the window).
If Haali renderer only supports YUY2 and RGB32, where does the colorspace conversion from YV12 happen?
System info:
1900MHz Athlon XP
Radeon 9800Pro (should be no slouch at PS 2.0 performance)
Tested with a few different catalyst drivers (5.12, 5.13, 6.1)
MPC 2006.02.26-2.2
The Haali renderer that came with the latest splitter
Windows XP SP2
