Hi ffmpeg users,

I am trying to use named pipe as the input of ffmpeg. I understand that the
default size of named pipe in linux is 65536 bytes. I am wondering how
often ffmpeg reads data from named pipe (is it as frequent as possible?),
and how large data buffer can be held by ffmpeg process once data are read
from named pipe, but not yet encoded (any RAM constraint?). Please could
anyone give me some advice. Thanks in advance!
