buffer

问题 Need help, I am getting buffer data using plugin and matching iframe tag. After getting buffer value, I am retrieving iframe src and replacing them with blank src. When I loop the src values and output and using preg_replace it does not replace value according to loop and replace with the first iframe values... Here is my code add_action('wp_footer', 'scheck_iframe_value'); function scheck_iframe_value() { $get_me_buffers = ob_get_clean(); $pattern = '@(.*)(<iframe(?:.*?)</iframe>)(.*)@m'; ob

问题 I need to convert buffer audio file .m4a to buffer audio file .wav for send to google speech api by NodeJS var toWav = require('audiobuffer-to-wav') var xhr = require('xhr') var context = new AudioContext() // request the MP3 as binary xhr({ uri: 'audio/track.mp3', responseType: 'arraybuffer' }, function (err, body, resp) { if (err) throw err // decode the MP3 into an AudioBuffer audioContext.decodeAudioData(resp, function (buffer) { // encode AudioBuffer to WAV var wav = toWav(buffer) // do

问题 I had wrote a node/ssjs program that makes: Tcp connection to data server(Apache MIMA), using TLS module. (OK) Encode/decode(serialize/deserialize) messages through protobuffer module.. (OK) Send serialized message to server and get response. (Not OK). The server´s manual types: Structure of message: [ Length | Header length | Header (| Body length |Body) ] Length – message length = fixed size (4 bytes). Note that this is only the size of following message (not the prefix itself); Header

问题 I see there is an array_split and split methods but these are not very handy when you have to split an array of length which is not integer multiple of the chunk size. Moreover, these methods input is the number of slices rather than the slice size. I need something more like Matlab's buffer method which is more suitable for signal processing. For example, if I want to buffer a signals to chunks of size 60 I need to do: np.vstack(np.hsplit(x.iloc[0:((len(x)//60)*60)], len(x)//60)) which is

问题 What's the optimal buffer size to use with a stream from HttpWebResponse.GetResponseStream()? Online examples vary from 256b to as much as 5Kb. What gives? I guess buffer sizes might be situational. If so what are the situations to use what type of buffer size? Thanks. 回答1: Really, it doesn't matter very much. Sure, if you use really small buffers, you may have to make a few extra calls down through the layers to get the bytes (though the stream is likely doing at least some buffering -- I

问题 I'm confused as to how the writing processing goes in C. So I have a string, s, that I want to write to the output. To do that, I use fputs: fputs(s, stdout); But apparently this does not write to the output, but merely collect the data for writing? Where exactly is it collected? So I have to wait until the program exits or till I call fflush() till the output is actually written into stdout? Am I right? 回答1: The C Standard IO streams are operating in one of three modes: fully buffered line

问题 How can I make the overlapping area of two sprites transparent in Unity? Could you write a shader about it? After some research, I learned that I should use stencil buffer, but I don't know how. This is vital to me. I have to complete this school project in 6 days. Please help .. = ( EXAMPLE IMAGE: 回答1: There you go, keep in mind this is the first time I'm using stencil so I might have done something less than optimal. But it works with sprites as you requested. // Upgrade NOTE: replaced 'mul

问题 I am playing around with building a chat application using PHP and CodeIgniter. For this, I am implementing a cache 'buffer' with memcached to hold the most recent chat messages in memory, reducing load on the database. What I want to do is this: When a message arrives, I save it in memcached using the current minute (YYYY-MM-DD-HH-MM) as the key. No database I/O involved. The idea being that all messages from the same minute are collected under the same key. Users receive new chat messages
