stream

问题 I'm working on a project which shows video advertisement to user and after 60 second users can see a link. My boss wants to be sure users watch all of 60 second. Now I want to know is there any way to check how much of a video stream has been seen by php ? To present video as stream I've used this code : http://codesamplez.com/programming/php-html5-video-streaming-tutorial class VideoStream { private $path = ""; private $stream = ""; private $buffer = 102400; private $start = -1; private $end

问题 I am using 32feet.net library for connecting with Bluetooth mobile phone. I have successfully discovered devices, successfully paired with device. I have successfully made a call using AT command with the help of Bluetooth dial with 32feet.net and c# I want to use the speaker and mic of laptop during the voice call going on the mobile phone. My C# code for dialing a call is BluetoothEndPoint bep = new BluetoothEndPoint(phone.DeviceAddress,BluetoothService.Handsfree); cli = new BluetoothClient

问题 I am using a file as a cache for big data. One thread writes to it sequentially, another thread reads it sequentially. Can I be sure that all data that has been written (by write() ) in one thread can be read() from another thread, assuming a proper "happens-before" relationship in terms of the Java memory model? Is this behavior documented? In my JDK, FileOutputStream does not override flush() , and OutputStream.flush() is empty. That's why I'm wondering... The streams in question are owned

问题 I am looking into stream reader timeout property. From the documentation, I did not understand, How this property works? What will happen when stream reader timeouts? Can somebody explain me these questions or point out to some better documentation than this. https://msdn.microsoft.com/en-us/library/system.io.stream.readtimeout(v=vs.110).aspx Sample code: TcpClient client = new TcpClient(serverIP, serverTcpPort); Stream s = client.GetStream(); StreamReader sr = new StreamReader(s); sr

问题 I try to send data from server (TcpListener) to client (TcpClient). I use Windows Form Application and the next code: Imports System.Text Imports System.Net Imports System.Net.Sockets Imports System.Threading Imports System.Runtime.InteropServices Public Class Form1 Private Server As TcpListener = Nothing Private ServerThread As Thread = Nothing Dim tcpclnt As TcpClient Dim stream As NetworkStream Public Shared bytes(1024) As Byte Public Shared data As String = Nothing Private Sub Form1_Load

问题 I am developing a real-time Android application and have an issue with detecting errors on an ObjectOutputStream which is connected to a TCP network Socket . I am calling writeObject followed by a flush on the stream as normal, however when the receiving node unexpectedly dies I need to know about it right away (within seconds). Unfortunately when the node goes down the server's call to writeObject and flush do not throw IOException s and instead succeed. I am assuming there is internal

问题 I want to extract audio from a video file using javascript, is it possible to make a mp3 file or any format so that i can play it in an audio tag in html5 ? if yes how? OR what API should I use ? 回答1: JavaScript is a script running at the client-end for handling user interactions usually. Long computations cause the browser to halt the script anyway and can turn the page unresponsive. Besides, it is not suitable for video encoding/decoding. You should use a Java applet for video processing

问题 I'm writing an application that signs and envelopes data using BouncyCastle . I need to sign large files so instead of using the CMSSignedDataGenerator (which works just fine for small files) I chose to use CMSSignedDataStreamGenerator . The signed files are being generated but the SHA1 hash does not match with the original file. Could you help me? Here`s the code: try { int buff = 16384; byte[] buffer = new byte[buff]; int unitsize = 0; long read = 0; long offset = file.length();

问题 I have a Bluetooth connection that works ok. When connected, I call this write function, that sends a stream to another device. It goes like this: public void Write(byte[] bytes) { System.Threading.Tasks.Task.Run(() => { int offset = 0; int count = 10; int len = bytes.Length; while (offset < len) { try { mmOutStream.Write(bytes, offset, Math.Min(count, len - offset)); offset += count; } catch (IOException ex) { System.Diagnostics.Debug.WriteLine("Error occurred when sending data", ex); } } })
