I'm writing a helper method in C#/ASP.NET that streams a file to the browser, and I would like to be able to detect if any content has been written to the browser prior to clearing the response headers/content and sending file bytes. If a page that makes a call to my helper method is not set up correctly, it seems like it would be possib...

The loadSound() method seems to work fine for this, but I need to be able to skip the MP3 to unbuffered regions of the audio timeline and to start it streaming/downloading from there. Anyone know how I can acc...
I'm trying to send a streaming response in a Rails application, specifically using the multipart/x-mixed-replace content type. As far as I can tell, streaming responses are not supported by Rails since the container tries to buffer and determine the length of the response body before sending anything to the client. Incidentally, we are...
Hello Everyone, Let's say I have a url to a streaming data source (for example a stream of updated weather data) and I know this url works with GET (I verified that it does return steaming data). The stream is compressed with GZIP, each "message" begins with a 1 byte id, a 2 byte part containing the message length, then another 2...

I'm working on a project where I need to batch convert files to multiple media formats, some of which will be streamed to iPhone. I'm using ffmpeg on a CentOS server, and have been using mediafilesegmenter locally to create m3u8 playlists, and it's gone swimmingly, but, in trying to get the process going on the unix server, I can't seem ...

The source MP4 file contains a number of video streams of different bitrates and a number of audio streams of different languages. When I call IGraphBuilder::AddSourceFilter for my source file, I get a filter t...
I'm working on a Hadoop streaming workflow for Amazon Elastic Map Reduce and it involves serializing some binary objects and streaming those into Hadoop. Does Hadoop have a maximum line length for streaming input? I started to just test with larger and larger lines but figured I would ask here first. ...
My first application got rejected for not using the HTTP Live Streaming Protocol. Ok, now I have done some reading, and apparently I need to re-encode with Apples 'HTTP Live Streaming Tools' my videos into various files so it can be streamed. So am I correct, that I don't have to change anything in my binary/code to refresh my app or is...
I'm starting to look into technologies to support a project that involves video chat between one party using a web browser and another party using a fat client (technology TBD, per below).

NSXMLParser allows SAX parsing of either an NSData block or from a URL source. The problem is that both these methods require the entire XML source to be known before parsing begins. Suppose I have a stream of XML Data (say a sequence of NSData objects) and I want to process the stream using NSXMLParser or another cocoa class, how can ...

Here: http://msdn.microsoft.com/en-us/library/system.io.streamreader.aspx you can see: "When reading from a Stream, it is more efficient to use a buffer that is the same size as the internal buffer of the stream.". According to this weblog , the internal buffer size of a Stream...
Hi Folks, Why some methods that write bytes/chars to streams takes int instead of byte/char?? Someone told me in case of int instead of char: because char in java is just 2 bytes length, which is OK with most character symbols already in use, but for certain character symbols (chines or whatever), the character is being represented in ...
