Absolutely. Though the decoding is done in the separate process and there is a large ring-buffer to connect decoder and encoder, the decoding is still a bottleneck on a fast multi-core processor. Fortunately mplayer-mt/ffmpeg-mt has multi-threaded H.264 decoding.

With "ultrafast" settings decoding may become a bottleneck for x264.
