  • iPhone HTTP Live Streaming not working on models below 3GS

    - by dreamer
    We are using http live streaming for on demand video from within our iPhone app and on the 3GS models the videos play as they are meant to. However, on the models pre 3GS it gives an error saying this movie format is not supported. I have seen other threads on this however no solutions or insights. Does anyone know if this really is a hardware limitation of the pre 3GS phones or does it have something to do with our code?

  • A weird crash...

    - by Nima
    Hi, I have a piece of code that runs in debug mode in VS2008, C++. The problem is that when I am debugging the code line by line, at a very weird point of the code, it crashes and says: debug assertion faild. Expression: _BLOCK_TYPE_IS_VALID(pHead-nBlockUse) The crash point is on the first closed curly bracket (after mesh-edges[e].needsUpdate=false;) I don't understand why on a curly bracket? does that make sense to you guys? Can anybody help me understanding what is going on..? for(int e=0; e<mesh->edges.size(); e++) { if(mesh->edges[e].valid && mesh->edges[e].v[0]>=0 && mesh->edges[e].v[1]>=0 && mesh->points[mesh->edges[e].v[0]].writable && mesh->points[mesh->edges[e].v[1]].writable) { //update v_hat and its corresponding error DecEdge Current = DecEdge(e); pair<Point, float> ppf = computeVhat(e); Current.v_hat = ppf.first; Current.error = ppf.second; edgeSoup.push(Current); mesh->edges[e].needsUpdate=false; } }

  • Live javascript debugging by recording function calls and parameters

    - by Jenko
    Is there a debugging system that allows me to record javascript function calls and their parameters as they occur? this would allow me to trace and debug applications in live/client situations without the performance hit due to manual logging. Edit: I'm not talking about manually calling functions using a 'console' window and viewing the results, or manually adding 'trace' or 'log' commands into my javascript. I need it to work with any running javascript.

  • Converting a DrawModel() using BasicEffect to one using Effect

    - by Fibericon
    Take this DrawModel() provided by MSDN: private void DrawModel(Model m) { Matrix[] transforms = new Matrix[m.Bones.Count]; float aspectRatio = graphics.GraphicsDevice.Viewport.Width / graphics.GraphicsDevice.Viewport.Height; m.CopyAbsoluteBoneTransformsTo(transforms); Matrix projection = Matrix.CreatePerspectiveFieldOfView(MathHelper.ToRadians(45.0f), aspectRatio, 1.0f, 10000.0f); Matrix view = Matrix.CreateLookAt(new Vector3(0.0f, 50.0f, Zoom), Vector3.Zero, Vector3.Up); foreach (ModelMesh mesh in m.Meshes) { foreach (BasicEffect effect in mesh.Effects) { effect.EnableDefaultLighting(); effect.View = view; effect.Projection = projection; effect.World = gameWorldRotation * transforms[mesh.ParentBone.Index] * Matrix.CreateTranslation(Position); } mesh.Draw(); } } How would I apply a custom effect to a model with that? Effect doesn't have View, Projection, or World members. This is what they recommend replacing the foreach loop with: foreach (ModelMesh mesh in terrain.Meshes) { foreach (Effect effect in mesh.Effects) { mesh.Draw(); } } Of course, that doesn't really work. What else needs to be done?

  • XNA model drawing problem

    - by user1990950
    When using this code: public static void DrawModel(Model model, Vector3 position, Vector3 offset, float xRotation, float yRotation, float zRotation, float allrot, float xScale, float yScale, float zScale) { position.Y *= -1; offset.Y *= -1; Matrix worldMatrix = ((Matrix.CreateRotationZ(MathHelper.ToRadians(zRotation)) * Matrix.CreateRotationX(MathHelper.ToRadians(xRotation))) * Matrix.CreateRotationY(MathHelper.ToRadians(yRotation))) * (Matrix.CreateTranslation(offset) * Matrix.CreateRotationY(MathHelper.ToRadians(allrot))) * Matrix.CreateScale(xScale, yScale, zScale); worldMatrix *= Matrix.CreateTranslation(position) * theCamera.GetTransformation() * Matrix.CreateTranslation(new Vector3(-(graphics.GraphicsDevice.Viewport.Width / 2), graphics.GraphicsDevice.Viewport.Height / 2, 0)); foreach (ModelMesh mesh in model.Meshes) { for (int i = 0; i < mesh.Effects.Count; i++) { ((BasicEffect)mesh.Effects[i]).EnableDefaultLighting(); ((BasicEffect)mesh.Effects[i]).World = worldMatrix; ((BasicEffect)mesh.Effects[i]).View = viewMatrix; ((BasicEffect)mesh.Effects[i]).Projection = projectionMatrix; } mesh.Draw(); } } The model rotates and then scales. It should scale and then rotate, but whenever I try to change it, it won't work.

  • Live chat rooms for learning ASP.NET?

    - by pkiyan
    I have come across a couple of sites in the past where a professional programmer would charge you 50 cents per minute or so to chat with them, one on one, and they would answer any questions you have about your choice of programming language. I've been studying ASP.NET 3.5 for a couple of months now and haven't been able to find a service like this for ASP.NET. Any help? A free live chat room for .NET would be of big help too.

  • triggering an event with jQuery live or delegate

    - by patrick
    I'd like to attach a handler to an element using either jQuery live() or delegate(). Looking at the docs I see I can attach the handler for a custom event. Is this possible for either of these jQuery functions to also trigger the handler? Basically I want to attach the handler function and run call it once. Thank you for any help.

  • Monovation: Assembly Injection into Live Processes

    - by FlappySocks
    I read this article by Miguel de Icaza on attaching an assembly into a live mono process. How is this any different to attaching a DLL to a running process? I do this already, but once the DLL is attached, it can't be unloaded without using an AppDomain (which I am trying to avoid). Miguel talks about "patch[ing] running programs", but I don't understand how. I cant find any other documentation or examples on this.

  • Where does abort() and terminate() "live"?

    - by user325016
    Regarding the terminate handler, As i understand it, when something bad happens in code, for example when we dont catch an exception, terminate() is called, which in turn calls abort() set_terminate(my_function) allows us to get terminate() to call a user specified function my_terminate. my question is: where do these functions "live" they don't seem to be a part of the language, but work as if they are present in every single cpp file, without having to include any header file.

  • Live Wallpaper Engine Abstraction

    - by user1459142
    I am trying to obtain an instance of my live wallpaper engine in another class, here is my code... In the other class: WallpaperEngine wpe = (WallpaperEngine) LiveWallpaperService.onCreateEngine(); In LiveWallpaperService: @Override public Engine onCreateEngine() { // TODO Auto-generated method stub return new WallpaperEngine(); } But when I refer to an object in my engine (i.e, "wpe.variable"), I get a NullPointerException and the wallpaper force closes.

  • cURL working on localhost but not on live website

    - by randyttp
    I have a small piece of script to grab images from a different website, works perfectly in localhost but does not work on on the live website. According to the phpinfo() on the site CURL is enabled. I can't post the script as its sensitive - But off the top of your head what things should I check for to solve this issue? Why would CURL work on localhost and other hosts, but not with others that also have CURL supposedly enabled?

  • Hyper-V virtual machine can't be migrated to a specific host in the cluster

    - by Massimo
    I have a three-node Hyper-V cluster running on Windows Server 2008 R2 which is working quite flawlessly: there are no errors, live migration works, all hosts can and will happily run all virtual machines, and so on. But one specific virtual machinee is trying to make me go mad: it works on two nodes of the cluster, but not on the third one. Whenever I try to move the VM to that node, be it in a live migration or with the VM powered off, it always fails. In the event log of the host these events are logged: Source: Hyper-V-VMMS Event ID: 16300 Cannot load a virtual machine configuration: General access denied error (0x80070005) (Virtual machine ID <GUID>) Source: Hyper-V-VMMS Evend ID: 20100 The Virtual Machine Management Service failed to register the configuration for the virtual machine '<GUID>' at 'C:\ClusterStorage\<PATH>\<VM>': General access denied error (0x80070005) Source: Hyper-V-High-Availability Event ID: 21102 'Virtual Machine Configuration <VM>' failed to register the virtual machine with the virtual machine management service. All other VMs can be moved to/from the offending host, and the offending VM can be moved between the other two hosts. Also, this is not a storage problem, because there are other VMs in the same cluster volume, and the host has no troubles running them. What's going on here?

  • clock and date showing on a live site but not on localhost

    - by grumpypanda
    I've got clock.swf and date.swf working fine on a live site, now I am using the same code to set up a local develop environment. Everything is working well except the clock.swf and date.swf stopped working on localhost. Two same yellow errors "You need to update your Flash plugin. Click here if you want to continue." but of course my Flash player is up to date since the live site is working fine. I'll post the code below which I think has caused the error. I've been searching online for the last couple of hours but no luck, anyone has got into an issue like this before? What can be the possible cause? Any help is appreciated. This is on the index.php, I can post more code here if needed. <?php embed_flash("swf/clock.swf", CLOCK_WIDTH, CLOCK_HEIGHT, "8", '', "flashcontent");?> <?php embed_flash("swf/date.swf", DATE_WIDTH, DATE_HEIGHT, "8", '', "flashcontent_date");?> configure.php define('CLOCK_WIDTH', '450'); define('CLOCK_HEIGHT', ''); define('DATE_WIDTH', '440'); define('DATE_HEIGHT', ''); flash_function.php <?php function embed_flash($name, $w, $h, $version, $bgcolor, $id) { $cacheBuster = rand(); $padTop = $h/3; ?> <style> a.noflash:link, a.noflash:visited, a.noflash:active {color: #1860C2; text-decoration: none; background:#FFFFFF;} a.noflash:hover {color:#000; text-decoration:none; background:#EEEEEE;} .message { width: <?=$w;?>px; font-size:12px; font-weight:normal; margin-bottom: 10px; padding: 5px; color: #EEE; background: orange;"} </style> <div id="<?=$id; ?>" align="center"> <noscript> <div class="message"> Please enable <a href="https://www.google.com/support/adsense/bin/answer.py?answer=12654" target="_blank" class="noflash">&nbsp;JavaScript&nbsp;</a> to view this page properly. </div> </noscript> <div class="message"> You need to update your Flash plugin.

  • How do I set up live audio streams to a DLNA compliant device?

    - by Takkat
    Is there a way to stream the live output of the soundcard from our 12.04.1 LTS amd64 desktop to a DLNA-compliant external device in our network? Selecting media content in shared directories using Rygel, miniDLNA, and uShare is always fine - but so far we completely failed to get a live audio stream to a client via DLNA. Pulseaudio claims to have a DLNA/UPnP media server that together with Rygel is supposed to do just this. But we were unable to get it running. We followed the steps outlined in live.gnome.org, this answer here, and also in another similar guide. As soon as we select the local audio device, or our GST-Launch stream in the DLNA client Rygel displays the following message and the client states it reached the end of the playlist: (rygel:7380): Rygel-WARNING **: rygel-http-request.vala:97: Invalid seek request This is how we configured GST-Launch in rygel.conf: [GstLaunch] enabled=true launch-items=mypulseaudiosink mypulseaudiosink-title=Audio on @HOSTNAME@ mypulseaudiosink-mime=audio/x-wav mypulseaudiosink-launch=pulsesrc device=<device> ! wavpackenc For <device> we tried with the default sink name, this name appended with .monitor, and in addition with upnp-sink and upnp.monitor that was created when we selected DLNA media server from paprefs. We also tried to encode using lamemp3enc with no luck. These are our pulseaudio modules: http://paste.ubuntu.com/1202913/ These are our sinks: http://paste.ubuntu.com/1202916/ Did we miss any other additional configuration needed to get this running? Are there any other alternatives for sending the audio of our soundcard as live stream to a DLNA client?

  • jQuery Not Selector and Live Binding

    - by ahsteele
    I am trying to bind all of the a elements on a page except for those with the title attribute of on. The code below ends up not attaching the click event to any of the a elements on the page. If I remove the not it works but of course binds to a elements I do not want the code applied to. What am I doing wrong with the not selector? $(document).ready(function() { $('a').not('title=on').live('click', function(event) { ... }); });
