VLC Webcam Streaming: How to go from a single stream to parallel streaming efficiently?
You will have to use some streaming service. Very likely it will cost you a pretty penny, if you want to tailor it to your needs (embedding on your website, changing design and so on). Try Livestream.com, Ustream, TV1.EU Or you may set up your own streaming service with the help of RED5 or ErlyVideo

What I need to know to do asp.net streaming
To limit the video as per your requirement you need to use GenericHandlers in asp.net. It must be designed in such a way that the url must expire after reaching the above condition. For Example, you can generate a random key that should append with the url (ie, QueryString) and store it in Database along with the time of generation. You can make the key expire after 3 hours then. To play the video on your website you can add jQuery plugin videojs. The documentation will help you to add that simple HTML5+Flash video player.

Streaming a video with PHP
The issue is in the range download function.In this function you are headers are correct.but you are printing the complete file as the response. These changes should fix your problem. // Notify the client the byte range we'll be outputting header("Content-Range: bytes $start-$end/$size"); header("Content-Length: $length"); Here you need to seek the file to start specified in the content-range headers. fseek($fp,$start) /* MISSING CODE */ Inserting the above line should fix your problem. // Start buffered download $buffer = 1024 * 8; while(!feof($fp) && ($p = ftell($fp)) <= $end) { if ($p + $buffer > $end) { // In case we're only outputtin a chunk, make sure we don't // read past the length $buffer = $end - $p + 1; } set_time_lim

Is there any public streaming api?
There is no streaming API for GitHub. I doubt they have plans of adding one either to be frank. Your initial request can get the last 30 events and then poll with the ETag header of that request for updates. You'll need to be authenticated (somehow, not necessary via an app) to make it work. Considering each request should come from a different IP address I would hazard a guess that the rate-limits wouldn't be applied globally to all visitors regardless of who they're authenticating as. That, however, would be an excellent question for the API support team at GitHub.

Nodejs mp3 streaming
One very simple reason why you are getting the first response 'in here' is probably because your browser is looking for a favicon file, which your node application responds with a 404. This is what I have generally observed when you try to write a simple app in node.js. As to why the audio isn't streaming, I have to look into it properly. But I don't know why you are trying to set a content-length as node.js httpServer, as it supports writing chunked responses (Transfer-Encoding: chunked) by default (which is what you need for streaming). There is something obviously wrong with this approach, but I will have to look into it properly to give you a definate answer.

Streaming .asf on android
Generic Android (AOSP) supports very limited set of codecs and containers - see http://developer.android.com/guide/appendix/media-formats.html Some devices do support additional codecs/containers, but as non-standard extension. ASF with MJPEG stream is not supported by AOSP. But it shouldn't be too hard to implement it in the user mode - this is a camera, so you don't need to worry about stream position (for seek and rewind) and MJPEG is simple to decode and display. Just read the stream and display as a sequence of frames.

Streaming an IEnumerable
The TextReader Class exposes multiple methods to read data. If you pass an instance to some external code, it may use any of the methods, not just the ReadLine Method. The methods that you need to override at a minimum are the Read Method and the Peek Method. If you don't override them, they both always returns -1, indicating that the end has been reached. All other methods, including the ReadLine Method, provide default implementations based the Read Method. You can override them (for example, for improved performance), but you are not required to. From MSDN: Notes to Inheritors A derived class must minimally implement the Peek and Read methods to make a useful instance of TextReader. So your implementation does not work as is.

HLS streaming onto IOS devices
It's normal that when the playlist is for a live stream (without the #EXT-X-ENDLIST) that the client will start playing a few segments from the end of the playlist. This is because it expects that the playlist will be continually updated with more segments and the client will retrieve the playlist in a loop. You can fix it just by adding the #EXT-X-ENDLIST tag at the end of the playlist. Or maybe you expect that the stream continues to grow, in that case, you can try with an event playlist with this tag: #EXT-X-PLAYLIST-TYPE:EVENT The expected behavior of the client is not specified, so I don't know for sure if the application will start playing it from the beginning, but at least it should be able to seek to the start.

Threading with Hadoop Streaming
I tried to use threading with python, there were issues with the Global Interpreter Lock. Ported code to use the multiprocessing module, internally hadoop assigns as many mappers as there are cores in the cluster, hence multiprocessing is not the way to go if you need speed up. Multithreading if performed right might give some speedup

Audio Streaming from Microphone
Create a new WaveIn object call StartRecording in the DataAvailable event handler, transmit args.BytesRecorded bytes from args.Buffer across the network. Note that this will mean you are transmitting PCM, which is not very efficient. Normally for network streaming you would use a codec. In the NAudioDemo source code there is a Network Chat demo showing this in action.

Video not streaming mysql php
Is there anything in your database tables? If there isn't, you would be able to run the script, and it would run without any output or errors. The mysql query wouldn't fail, and the while loop would never run. Try putting something like this that checks to see if you get any data returned from your query. var_dump($result); And depending on the output now, as it will print something, even if there isn't any data in your table, people can have an easier time finding problems.

You need to take off the leading contrib from you paths

Hadoop streaming fails in R
HADOOP_HOME should be a directory. HADOOP_CMD should be a program. So since they are set to the same thing, that's wrong right there. But HADOOP_CMD should supersede HADOOP_HOME so that shouldn't be the root cause. So the only option left is debugging. If you had read the debugging guide you would have digged out stderr and would know a lot more already. With the console output only, there's nothing to work on.

Live streaming video in Qt
Decoding is no problem. You can use the QMediaPlayer class. Under Linux it actually uses the gstreamer libs. Encoding is not implemented. This is a bit beyond the scope of Qt5. And don't let the classes QMediaRecorder or QVideoEncoderSettings confuse you. They are mainly helper classes for QCamera or QRadioTuner, which provide an already encoded stream from their devices. If you need to encode single images into video frames and put them into a container, you need a 3rd party lib like ffmpeg. Streaming a video from on pc to another is easily implemented with Qt5. Encoding or transcoding cannot be done with Qt5 alone.

Streaming in a char Number
You are reading a char at a time, which means you get '1', '3', skips the space, '1', '4', skips the space, etc. To read the values as NUMBERS, you need to use an integer type as a temporary: unsigned short s; bytes >> s; myChars[i] = s; Now, the stream will read an integer value, e.g. 13, 14, and store it in s. Then you convert it to a unsigned char with myChars[i] = s;.

SoundManager2 and Streaming URLs
The URL you're using is pointing to an m3u file. To get it playing via SoundManager you need to point directly to the streaming URL: http://stereo.wavestreamer.com:3056/Live (extracted from the m3u file). To get other "streams" like that playing you'll need to build some javascript that makes an ajax request to get the listen.m3u file and then extracts the actual stream URL from the playlist.

Streaming video with Xuggler
I think you need to do something like this: IContainer iContainer = IContainer.make(); if (iContainer.open(inputStream, IContainer.Type.READ, format) >= 0) { IMediaReader mediaReader = ToolFactory.makeReader(iContainer); ... } ... based on what the javadocs say. It looks like the format needs to be obtained using static methods of the IContainerFormat class. If you supply a null format, the open method will attempt to guess the container type ... apparently.

RTSP Streaming on iOS 6 with Xcode 4.6.1
I've examined many of those projects that you mentioned, and experienced on those well.. You can use ffmpeg libraries to make a rtsp streaming client, as ffmpeg supports rtsp protocol... But there is an important issue which I've seen in my tests that ffmpeg's rtsp protocol has some important issues when using UDP transport layer for streaming... Even with the latest version (2.01) many RTP packets are dropping during streaming so images become glitchy sometimes... If you use TCP or http transport layer, then it works well... For live555 project, this library works well with both UDP and TCP transports when streaming rtsp streams.. But ffmpeg is so much powerful/has many capabilities than live555. If you decide to use ffmpeg then, basically, you should follow the below steps, make a

SAXON Streaming XPath in .NET
You might find that the best way to tackle this is using Saxon's XQuery with document projection. Essentially this works by filtering the event stream from the XML parser and building a tree that only contains the nodes that contribute to the result of the query. XQuery works better than XSLT for this because it's more amenable to static analysis, as it lacks the polymorphism of XSLT's template rules. By a strange coincidence, my colleague O'Neil Delpratt has been working on test cases for the .NET API and spotted today that there's no direct way of invoking XQuery document projection using that API. Take a look at it though, and try it from the command line or from Java; I'm sure it can be done in .NET, it might just require digging in a bit deeper than the public API. To do the same th

Unity3d web and streaming scenes
When using a streamed build the player will include all the levels that have been set up in the build settings in the order in which they appear in the build settings. Depending on how large your levels are, this might even be sufficient when having a "random access" use case. Since you can check the current progress of level loading using GetStreamProgressForLevel you could simply display a "loading" dialog if the player selects a level which is not yet ready. If you have like 10 levels 150kb each, that would be a 1.5mb download at max, which could be downloaded within a few seconds on a reasonably fast internet line. If you need something that is non-linear AND has large levels, you need to go the asset bundles route. Building asset bundles requires Unity Pro and you can only do it w

Android video streaming from url
There are some requirements for streaming to work. The file might not be encoded "correctly" http://developer.android.com/guide/appendix/media-formats.html For video content that is streamed over HTTP or RTSP, there are additional requirements: For 3GPP and MPEG-4 containers, the moov atom must precede any mdat atoms, but must succeed the ftyp atom. For 3GPP, MPEG-4, and WebM containers, audio and video samples corresponding to the same time offset may be no more than 500 KB apart. To minimize this audio/video drift, consider interleaving audio and video in smaller chunk sizes. You might be on an older version of Android that doesn't support it HTTP progressive streaming was only added in 2.2, HTTPS only supported 3.0+, Live streaming is only supported in even later v

Twitter streaming api hangs
Well it's a streaming API, so it will stream infinitely. Hence if you are trying to read to the end of stream, it will block forever until you run out of memory or get disconnected due to network error etc. You need to process the data while connected to the stream. If I were you I'd just use a client library (see https://dev.twitter.com/docs/twitter-libraries).

Video Streaming in WPF Application
My first thought was to just open the file using a decryption stream, but apparently MediaElement doesn't allow you to play a stream directly. If having the unencrypted file left the user's file system isn't a problem, you could just decrypt the file as one step, then assign the source of the MediaElement to the decrypted file. If leaving the unencrypted version laying around isn't an option, then you will likely need to investigate another playback component (some are outlined in the answer I referenced above).

Streaming XML Mime Type?
Sounds like apart from your streaming requirements, your content is actually a Multipart message with several application/xml parts. With this layout application/json parts could also be mixed in your message. If your individual XML Fragments are part of larger documents take a look at the (somewhat old and understated) XML Fragment Interchange W3C Candidate Recommendation. It defines a nice syntax to wrap fragment bodies together with contextual information about the original document.

Streaming JPEGs from a Cellphone Camera
I've done something similar and ended up moving that into native code and made a JNI call to convert from NV21 and stick onto a circular buffer. Have a 2nd thread read off the buffer and do the network IO so you can return from onPreviewFrame as quickly as possible. Even better, copy the nv21 data to the circular buffer and have that 2nd thread do the jpg conversion before sending the data on the network. by the way, I did this for a video chat client. It worked well but I've since moved to sending H.263 frames. It's more efficient than sending JPGs if you are also doing a video chat client.
