• How to stream partial content with ASP.NET MVC FileStreamResult

  - by o_o

  We're using a FileStreamResult to provide video data to a Silverlight MediaElement based video player: public ActionResult Preview(Guid id) { return new FileStreamResult( Services.AssetStore.GetStream(id, ContentType.Preview), "application/octet-stream"); } Unfortunately, the Silverlight video player downloads the entire video file before it starts playing. This behavior is expected as our Preview Action does not support downloading partial content. (side note: if the file is hosted in an IIS virtual directory we can start playback at any location in the video while it is still downloading. however for security and auditing reasons we can't provide a direct download link. so this is not an option.) How can we improve the Controller Action to support partial HTTP content? I assume we first have to inform the client that we support it (adding an "Accept-Ranges:bytes" header to a HEAD request), then we have to evaluate the HTTP "Range" header and stream the requested file range with a response code of 206. Will that work with ASP.NET MVC hosted on IIS6? Is there already some code available? Also see: http://en.wikipedia.org/wiki/List_of_HTTP_headers http://blogs.msdn.com/anilkumargupta/archive/2009/04/29/downloadprogress-downloadprogressoffset-and-bufferprogress-of-the-mediaelement.aspx http://benramsey.com/archives/206-partial-content-and-range-requests/

• what is the best way to stream a audio file to website users/listners

  - by Naveen Chamikara Gamage

  I'm developing a music site which will stream audio files stored in a server to users, audio files will be played through flash player placed in a webpage.. As I heard I need to use a streaming media server for streaming audio files ( like 2mb to 3mb in size).. Do I need to use one? I found some streaming media server softwares like http://www.icecast.org - but as in their documentation, It is used for streaming radio stations and live streaming purposes, but I just need to stream audio files faster and in low size (low bandwidth) with good quality.. I heard I need to encode the audio files first and then send them to listeners and in their end audio files need to be decoded again. Is that true? How can I do that? if I need to use a special web server, where should I host my files? Any good hosting providers? if I host audio files in a normal web server, they will use HTTP or TCP to deliver my audio files to users/ listners but I found that HTTP and TCP are not good ways to use for multi media purposes like streaming audio and video files, and they are used for delivering HTML and stuff. I found I should use RSTP or UDP for streaming audio files.. What should I use? I know that .MP3 files has much better quality than the other formats but it also gives huge size to the audio files.. which format should I use for audio files? Most of the best quality audio files are more than 7mb so I'm planning to convert them my self using a software so I could get low size files with some level of good quality. If I'm converting my audio files what is the good BITRATE I should use for my files? Any known best softwares for converting audio files while keeping quality in a good level? Note** - I know that I will not need complex requirements at the beginning of the site but I wanted to what are the best ways like they are using for soundcloud.com

• Audio stream mangement in Linux

  - by User1

  I have a very complicated audio setup for a project. Here's what we have: 3 applications playing sound 2 applications recording sound 2 sound cards I really don't really have the code to any of these applications. All I want to do is monitor and control the audio streams. Here are a few examples of operations I'd like to do while the applications are running: Mute one of the incoming audio streams. Have one of the incoming audio streams do a "solo" (be the only stream that can "talk"). Get a graph (about 30 seconds worth) of the audio that each stream produced. Send one of the audio streams to soundcard #1, but all three audio streams to soundcard #2. I would likely switch audio streams every 2 minutes or so with one of the operations listed above. A GUI would be preferred. I started looking at the sound systems in Linux and it gets extremely complex and I feel like there have been many new advances in the past few years. I see jack, pulseaudio, artsd, and several other packages. They all have some promise but where should I start? Is there something someone already built that can help?

• Java - Save video stream from Socket to File

  - by Alex

  I use my Android application for streaming video from phone camera to my PC Server and need to save them into file on HDD. So, file created and stream successfully saved, but the resulting file can not play with any video player (GOM, KMP, Windows Media Player, VLC etc.) - no picture, no sound, only playback errors. I tested my Android application into phone and may say that in this instance captured video successfully stored on phone SD card and after transfer it to PC played witout errors, so, my code is correct. In the end, I realized that the problem in the video container: data streamed from phone in MP4 format and stored in *.mp4 files on PC, and in this case, file may be incorrect for playback with video players. Can anyone suggest how to correctly save streaming video to a file? There is my code that process and store stream data (without errors handling to simplify): // getOutputMediaFile() returns a new File object DataInputStream in = new DataInputStream (server.getInputStream()); FileOutputStream videoFile = new FileOutputStream(getOutputMediaFile()); int len; byte buffer[] = new byte[8192]; while((len = in.read(buffer)) != -1) { videoFile.write(buffer, 0, len); } videoFile.close(); server.close(); Also, I would appreciate if someone will talk about the possible "pitfalls" in dealing with the conservation of media streams. Thank you, I hope for your help! Alex.

• MS Source Server - source stream is apparently not there when viewing with srctool

  - by Tim Peel

  Hi, I have been playing around with the MS Source Server stuff in the MS Debugging Tools install. At present, I am running my code/pdbs through the Subversion indexing command, which is now running as expected. It creates the stream for a given pdb file and writes it to the pdb file. However when I use that DLL and associated pdb in visual studio 2008, it says the source code cannot be retrieved. If I check the pdb against srctool is says none of the source files contained are indexed, which is very strange as the process prior ran fine. If I check the stream that was generated from the svnindex.cmd run for the pdb, srctool says all source files are indexed. Why would there be a difference? I have opened the pdb file in a text editor and I can see the original references to the source files on my machine (also under the srcsrv header name) and the new "injected" source server links to my subversion repository). Should both references still exist in the pdb? I would have expected one to be removed? Either way, visual studio 2008 will not pick up my source references so I am a bit lost as to what to try next. As far as I can tell, I have done everything I should have. Anyone have similar experiences? Many thanks.

• Pros and cons of MPMoviePlayerController versus launching UIWebView to stream movie

  - by Nosredna

  I have a client who has video content for the web in Flash format. My task is to help them show the videos in an iPhone app. I realize that step one is to get these videos into the appropriate Quicktime format for the iPhone. Then I'm going to have to help the client figure out how or where to host these files. If that's tricky I assume they can be hosted at YouTube. My chief concern, though, is which approach to take to stream the video. What are the pros and cons of MPMoviePlayerController versus launching UIWebView with the URL of the stream? Is there any difference? Is one of them more or less forgiving? Is one of them a better user experience? Any gotchas I might expect to run into? I'm assuming playing video is pretty easy on the iPhone. Is it reasonable to try both and have one available as a fallback, or would that be a waste of time? I'm trying to schedule this out a bit, so I'd love to hear real-world experiences from anyone who's done this.

• Capture data read from file into string stream Java

  - by halluc1nati0n

  I'm coming from a C++ background, so be kind on my n00bish queries... I'd like to read data from an input file and store it in a stringstream. I can accomplish this in an easy way in C++ using stringstreams. I'm a bit lost trying to do the same in Java. Following is a crude code/way I've developed where I'm storing the data read line-by-line in a string array. I need to use a string stream to capture my data into (rather than use a string array).. Any help? char dataCharArray[] = new char[2]; int marker=0; String inputLine; String temp_to_write_data[] = new String[100]; // Now, read from output_x into stringstream FileInputStream fstream = new FileInputStream("output_" + dataCharArray[0]); // Convert our input stream to a BufferedReader BufferedReader in = new BufferedReader (new InputStreamReader(fstream)); // Continue to read lines while there are still some left to read while ((inputLine = in.readLine()) != null ) { // Print file line to screen // System.out.println (inputLine); temp_to_write_data[marker] = inputLine; marker++; }

• Reading data from an open HTTP stream

  - by allenjones

  Hi, I am trying to use the .NET WebRequest/WebResponse classes to access the Twitter streaming API here "http://stream.twitter.com/spritzer.json". I need to be able to open the connection and read data incrementally from the open connection. Currently, when I call WebRequest.GetResponse method, it blocks until the entire response is downloaded. I know there is a BeginGetResponse method, but this will just do the same thing on a background thread. I need to get access to the response stream while the download is still happening. This just does not seem possible to me with these classes. There is a specific comment about this in the Twitter documentation: "Please note that some HTTP client libraries only return the response body after the connection has been closed by the server. These clients will not work for accessing the Streaming API. You must use an HTTP client that will return response data incrementally. Most robust HTTP client libraries will provide this functionality. The Apache HttpClient will handle this use case, for example." They point to the Appache HttpClient, but that doesn't help much because I need to use .NET. Any ideas whether this is possible with WebRequest/WebResponse, or do I have to go for lower level networking classes? Maybe there are other libraries that will allow me to do this? Thx Allen

• Android, phone call audio stream via wlan

  - by moppel

  I am planning on developing my specific voip app for android. Here's the scenario: when a phone call occurs I want to hear the person who's calling on my local pc speakers and I want to speak to him via my own pc microphone / headset. So I need to send the audio stream of both me and the person I am talking to via the wlan network. Something like this: ... onCallStateChanged(int state, String phoneNumber){ while(state == PhoneListener.CALL_STATE_OFFHOOK){ //while phone call is happaning //send incoming speech via wlan to pc //receive audiostream from pc microphone and direct it to the phone call } } ... Is this possible with the current Android API? (Actually it should be since voip apps are available in the market) I did some research in the Android API and all I found was the AudioManager which has constant named public static final int STREAM_VOICE_CALL; //The audio stream for phone calls But I don't know how to use it our how it should give me access to the actual audiostreams which I can send via network. How do I manage to do this? The connection would be realised by TCP sockets.

• Convert InputStream to String with encoding given in stream data

  - by Quentin

  Hi, My input is a InputStream which contains an XML document. Encoding used in XML is unknown and it is defined in the first line of XML document. From this InputStream, I want to have all document in a String. To do this, I use a BufferedInputStream to mark the beginning of the file and start reading first line. I read this first line to get encoding and then I use an InputStreamReader to generate a String with the correct encoding. It seems that it is not the best way to achieve this goal because it produces an OutOfMemory error. Any idea, how to do it ? public static String streamToString(final InputStream is) { String result = null; if (is != null) { BufferedInputStream bis = new BufferedInputStream(is); bis.mark(Integer.MAX_VALUE); final StringBuilder stringBuilder = new StringBuilder(); try { // stream reader that handle encoding final InputStreamReader readerForEncoding = new InputStreamReader(bis, "UTF-8"); final BufferedReader bufferedReaderForEncoding = new BufferedReader(readerForEncoding); String encoding = extractEncodingFromStream(bufferedReaderForEncoding); if (encoding == null) { encoding = DEFAULT_ENCODING; } // stream reader that handle encoding bis.reset(); final InputStreamReader readerForContent = new InputStreamReader(bis, encoding); final BufferedReader bufferedReaderForContent = new BufferedReader(readerForContent); String line = bufferedReaderForContent.readLine(); while (line != null) { stringBuilder.append(line); line = bufferedReaderForContent.readLine(); } bufferedReaderForContent.close(); bufferedReaderForEncoding.close(); } catch (IOException e) { // reset string builder stringBuilder.delete(0, stringBuilder.length()); } result = stringBuilder.toString(); }else { result = null; } return result; } Regards, Quentin

• Google App Engine - How to implement the activity stream in a social network

  - by spidee

  I want some ideas on the best practice to implement an activity stream for a social network im building in app engine (PYTHON) I first want to keep a log for all activities of each user - so that we have a history. i.e. someone became a friend, added a picture, changed their address etc. This way we have a users history available should we need it. Also mean we can remove friendship joins, change user data but have a historical log. I also want to stream a users activity to their friends. for this only the last X activities need to be kept - that is in the scenario that messages are sent to friends when an activity occurs. Its pretty straight forward designing a history log - ie: when, what, where. The complication comes as to how we notify friends of a user as to their activity. In our app friendships are not mutual - ie they are based on the twitter following model. Some accounts could have thousands of followers. What is the best approach to model this. using a many to many join table and doing a costly query - using a feed class that fired a copy of the activity to all the subscribers - maybe into mcache? As their maybe a need to fire thousands of messages i would imagine a cron job would need to be used. Any help ideas thoughts on this Thx

• How to stream authenticated content with MediaPlayer on Android

  - by 102790073222983779908

  I've seen quite a few posts askign this question on SO but there doesn't seem to be a definitive answer (or at least an answer I like!) I've got content protected behind basic auth (username/password) -- I can download it fine using the various HTTP download clases but for the life of me I can't sort out how to tell media player to stream it (and provide the authentication). I saw one post that suggested it wasn't possible since the MediaPlayer is all native code and doesn't things like the Authenticator. There are plenty of examples of how to first download to a cached copy and then play that back but....That sort of sucks (and the files maybe 100's of MB's). I saw at least one proposal to download it in smalish chunks and then start & stop the playback (redirecting to the new file) but that sort of sucks also since there would (I presume) be a stutter (I haven't tried it though) The best idea I have at this point is to start downloading to a cache file and then when it's 'full enough' start up playback while I continue to fill the file.... I hope that this works (but again, haven't tried it). Am I missing something obvious? It's so painful to have all the various pieces almost working and I sort of convinced myself that there had to be a way to natively stream protected content (or have it take a already established & qualified InputStream) but it appears no joy. BTW I'm a Mac/iPhone guy and a newb at Android so I'm still fighting a bit of Java learning.... Excuse me if I'm missing somthing obvious. -john

CRM Highlights for OpenWorld '12. Also, don't forget you can add on the Customer Experience Summit @ OpenWorld to make your week even more complete and get involved with the Experience Revolution! Below is a highlight of only some of the RightNow related sessions at OpenWorld. Please use OpenWorld Schedule Builder or check the OpenWorld Content Catalog for all of the session details and any time or location changes. Tip: Pre-enrolled session registrants via Schedule Builder are allowed into the session rooms before anyone else, so Schedule Builder will guarantee you a seat. Many of the sessions below will likely be at capacity. No better way to start off than hearing where Oracle RightNow is going! Oracle RightNow CX Cloud Service Vision and Roadmap (CON9764) - Oct 1, 10:45 AM. Oracle RightNow CX Cloud Service combines Web, social, and contact center experiences for a unified, cross-channel service solution in the cloud, enabling organizations to increase sales and adoption, build trust, strengthen relationships, and reduce costs and effort. Come to this session to hear from David Vap and his team of Oracle experts about where the product is going and how Oracle is committed to accelerating the pace of innovation and value to its customers. Interested in the Cloud and want to know why some leading CIOs are moving to the cloud? You can hear first hand from CIOs from Emerson, Intuit and Overstock.com: CIOs and Governance in the Cloud (CON9767) - Oct 3, 11:45 AM.   And of course there are a number of sessions that drill down into more specific areas. Here are just a few: Deliver Outstanding Customer Experiences: Oracle RightNow Dynamic Agent Desktop Cloud Service (CON9771) - Oct 1, 4:45 PM. This session covers how companies have delivered exceptional customer experiences and how the Oracle RightNow Dynamic Agent Desktop Cloud Service roadmap will evolve in the future.

Self-Service in the Age of Data Intimacy (CON11516) - Oct 1, 3:15. Even though businesses are generating more and more data around their relationships and interactions with customers, very little of the information a business generates ends up available to the contact center and even less is made available to the online service experience. The generic one-size-fits-all approach that typifies most online service experiences ultimately fails to address all user needs, and that failure ultimately leads to the continued use of high-cost agent-assisted channels for low-value interactions. This session introduces Oracle RightNow Web Experience’s Virtual Assistant and discusses how you can deliver rich, engaging, highly personalized experiences with the quality of agent-assisted service at a much lower cost. Improve Chat Experiences: Best Practices for Chat Pilots and Deployments (CON11517) - Oct 1, 4:45 PM.

From setting goals and metrics and training staff to customizing and tuning the solution, this session provides best practices and lessons learned from a broad set of implementations to help you get the most out of your chat solution. Differentiated Experience with Web Service (CON9770) - Oct 2, 1:15 PM. A reputation for excellent customer service can differentiate your brand and drive revenue. In this session, learn how to develop that reputation by transforming your online self-service into a highly interactive, branded customer experience. See live examples of how Oracle RightNow Web Experience has helped customers deliver on their Web service strategies. Unifying the Agent’s Engagement Console (CON11518) - Oct 2, 1:15 PM. Does your customer experience suffer because your agents are toggling between multiple tools? Do your agent productivity and morale suffer as well? Come to this session to learn how Oracle RightNow CX Cloud Service seamlessly unifies these disparate systems into a single engagement console. Regardless of channel, powerful adaptive tools consistently guide agents across contextually aware personalized workflows. Great agent experiences drive great customer experiences. Oracle RightNow CX Cloud Service and the Oracle Customer Experience Portfolio (CON9775) - Oct 3, 10:15 AM. This session covers how Oracle’s integrated suite of customer experience (CX) products fits with the Oracle CX portfolio of products (Oracle Fusion Customer Relationship Management; the Oracle ATG, Oracle Endeca, and Oracle Knowledge product families; and Oracle Business Intelligence) to increase revenues, strengthen customer relationships, and reduce costs across the entire end-to-end customer lifecycle for companies that sell to consumers and those that sell to businesses.

• How to download file into string with progress callback?

  - by Kaminari

  I would like to use the WebClient (or there is another better option?) but there is a problem. I understand that opening up the stream takes some time and this can not be avoided. However, reading it takes a strangely much more amount of time compared to read it entirely immediately. Is there a best way to do this? I mean two ways, to string and to file. Progress is my own delegate and it's working good. FIFTH UPDATE: Finally, I managed to do it. In the meantime I checked out some solutions what made me realize that the problem lies elsewhere. I've tested custom WebResponse and WebRequest objects, library libCURL.NET and even Sockets. The difference in time was gzip compression. Compressed stream lenght was simply half the normal stream lenght and thus download time was less than 3 seconds with the browser. I put some code if someone will want to know how i solved this: (some headers are not needed) public static string DownloadString(string URL) { WebClient client = new WebClient(); client.Headers["User-Agent"] = "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/532.5 (KHTML, like Gecko) Chrome/4.1.249.1045 Safari/532.5"; client.Headers["Accept"] = "application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5"; client.Headers["Accept-Encoding"] = "gzip,deflate,sdch"; client.Headers["Accept-Charset"] = "ISO-8859-2,utf-8;q=0.7,*;q=0.3"; Stream inputStream = client.OpenRead(new Uri(URL)); MemoryStream memoryStream = new MemoryStream(); const int size = 32 * 4096; byte[] buffer = new byte[size]; if (client.ResponseHeaders["Content-Encoding"] == "gzip") { inputStream = new GZipStream(inputStream, CompressionMode.Decompress); } int count = 0; do { count = inputStream.Read(buffer, 0, size); if (count > 0) { memoryStream.Write(buffer, 0, count); } } while (count > 0); string result = Encoding.Default.GetString(memoryStream.ToArray()); memoryStream.Close(); inputStream.Close(); return result; } I think that asyncro functions will be almost the same. But i will simply use another thread to fire this function. I dont need percise progress indication.
