Why does Crystal use decompressed data buffering? Is it faster?
There is the only negative thing in buffering – if DirectShow connects decompressor with video renderer quite well, it may be a little bit faster – decompressor draws in video memory directly but buffering requires one more memory copying. Positive things: buffer provides shock-absorption, it smoothes time usage while decompressing, you can also pause the playback and wait until buffer becomes full, you may order Crystal to do it automatically. Any way when you’re using filters or other on-screen effects the one more transfering arrears anyway – then the buffer is only positive feature.
