how many h264 encoder filters can use to encode 1920*1080 videos?
I use dshow like below
video capture(yuy2) ->inftee->h264 encode->sample grabber.
like this , when I connect two h264 encoder filter, it works well
but when I connect 3, the grabber will lost many frames
example: I set frame rate = 25.
when I get 100 frames use 5s.
but it should be 4s,
the CPU used = 36%
I find EncodeFrameAsync return busy many.
Does anyone tell me, what problem with it or how to inprove it?
