stream

问题 im currently working on a c++ application which is using a c library which needs a callback implemented from my side for example the callback is defined as this: int onWrite(char *what, char *buffer, size_t size, off_t offset); i have std::set which needs to be formated and written into buffer and take care of size and offset where size is buffer's size and offset how many bytes have already been processed is there a c++ way where i can stream-like into buffer? i think about something like

问题 My aim is recording stream and saving that stream into folders. The problem is, I have to save every 5 seconds long of stream into different folders. I mean for a 30 seconds long stream, there should be 6 folders. My code is working but I can't measure the seconds correctly, I divided the frames (a) into fps. But it did not give the correct result. Also I cannot save videos into different folders by using different names. I have to give different names but I don't know how to do it. import

问题 I want to ask about serialize/deserialize object with binary formatter. well i'm trying to deserialize object in FileStream that contain many objects that has been serialized one by one. The size of an object is too big to be saved in process memmory that's why i don't pack all of objects in one such as: List because they are too big in process memory So i serialize as much as needed in many times. with this way it won't take many process memmory because i just process one object alternately

In client side I have try the following. HttpResponseMessage file = httpclinet.GetAsync("url")

问题 I am doing the homework of CIS 194. The problem is to implement the ruler function by using streamInterleave . The code looks like data Stream a = Cons a (Stream a) streamRepeat :: a -> Stream a streamRepeat x = Cons x (streamRepeat x) streamMap :: (a -> b) -> Stream a -> Stream b streamMap f (Cons x xs) = Cons (f x) (streamMap f xs) streamInterleave :: Stream a -> Stream a -> Stream a streamInterleave (Cons x xs) ys = Cons x (streamInterleave ys xs) ruler :: Stream Integer ruler =

问题 Dear all I have following situation. I have several ISS Webservers hosting multiple web applications on each IIS server. The do have a public certificate on each system. Every IIS has an unique IP. All IIS Server are placed in the same DMZ I have setup an nginx System in another DMZ.

I don't want to have nginx break up

问题 Does anyone have any code or can point me in the right direction for integrating live555 into an iPhone app. I know that you can build the live555 C++ library for iOS but am not sure about the actual integration of this at a code level. A link to a tutorial or some code would be wonderful :) Thanks. 回答1: Download live555 here Unpack it somevhere (in my case /Volumes/OSX/live) find config.iphoneos an open it using text editor change LINK_OPTS to LINK_OPTS = -L. -arch armv7 --sysroot=$(SDK) -L$

问题 I'm writing a simple(ish) application that allows an internal system at work to request a copy process (using rsync) from a remote server to another remote server instigated using a REST call. I'm already familiar enough with the express framework, and have just started experimenting with the child_process library, and stumbled upon a small problem. I am successfully starting rsync processes using node's childProcess.spawn() , my issue is that rsync outputs its progress line-buffered with a
