Hello again!

So I did some tests on my PC and I`ve got interesting results.

I played video with -vo null twice, with -nosound in first case and
with -afm 1 in second case.
I wrote down VIDEO codec cpu usages at same times in video stream
for both cases. There were big differences between these values!
Is it possible? Is A-V sync so hard work? Or there is something
what I don`t know?

Test video parameters:
	
	VIDEO STREAM
	640x368
	24 bpp
	24 fps
	1001 kbps
	filefmt 3
	DLL: divx_c32.ax

	AUDIO STREAM
	samplerate 44100
	2 channels
	bps=2


And here are results, first value is position in video string in seconds,
second value is video codec cpu usage with '-vo null -nosound' and third
value is same thing with '-vo null -afm 1':

100	27%	34%
200	48%	53%
300	50%	85%
400	51%	87%
500	41%	65%
600	47%	78%
700	52%	86%
800	51%	88%
900	46%	90%
1000	48%	84%
1100	48%	78%
1200	48%	79%
1300	46%	70%
1400	43%	68%
1500	45%	75%
1600	45%	74%


audio codec cpu usage was 5% - 7% all the time...


hmmmm?

thanks......
