  • Broadcast live video from web-cam via plug-in

    - by Freebrainz
    Hello guys! Could you please suggest me what kind of software should I use to broadcast live video from webcam? Web-cam is connected via USB to my server. I want to broadcast video from my webcam on my web-page (HTML, ASP.NET - doesn't matter). I don't want to develop video broadcasting from the beginning - it takes a lot of time to implement good system. I'm looking for ready-to-use plug-in/widget for my site. I found ustream.tv, but live video start playing with delay about 2 seconds... You know, it's not real-time. I need something like Skype/icq/ooVoo... plug-in/widget for my web-site. Are these plug-ins exists in internet? P.S. I know that VideoLAN has ActiveX control. Does VLC provide me with real-time video broadcasting from webcam without any delays like Skype? Thank you!

  • Getting true video Height/Width from ASF videos

    - by David
    I am trying to convert an ASF video with FFMPEG using an interface called mediahandler. The issue is, the metadata on the ASF video appears to be corrupt. It states that the video is 640x240, and 4:3 aspect ratio. The aspect ratio is correct, but obviously the resolution is not. This causes the converter to incorrectly scale the video, because it uses the resolution to determine the original aspect ratio. I am able to get the aspect ratio metadata, but I'm not sure this solves the issue, because I would think that if the resolution could be incorrect, then so could the aspect ratio metadata. So, is there any way to get the actual height/width? It appears that players like VLC have no issue with this. How do I do such a thing w/ FFMPEG?

    - by Surya sasidhar
    Hi, I am using flvplayer.swf player, it is playing the videos,but before playing the video the player has black screen and a play button. When I click the play button the video plays. Is it possible to show a screen-shot of the video with the play button on top, instead of the blank screen? This is the code of my player: <embed id="fl" src="flvplayer.swf" bgcolor="#FFFFFF" align="left" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" flashvars="file=hospitaldemo.swf&autostart=false&frontcolor=0xCCCCCC&backcolor=0x000000&lightcolor=0x996600&showdownload=false&showeq=false&repeat=false&volume=100&useaudio=false&usecaptions=false&usefullscreen=true&usekeys=true" style="width: 400px; height: 350px"> </embed>

  • html5 video player with simplest controls (only play and paus)

    - by mathiregister
    hi guys, somehow there are really little tutorials out there for html5 video and audio playback. I simply want to embed video and audio files with customized controls. However the controls should be farely simple. I only need a play-button. If clicked, play gets replaced by pause. that's all! however i even don't know how to embed/display a video without "preload controls". Somehow if i only set (without preload controls) Firefox even don't shows anything. Chrome does show a black window. I would love to be able to use jquery to control the video play and pause button. Maybe you have some little start-approach for me! thank you very much!

  • VB.NET - cannot get Video Preview to work

    - by Yiu Korochko
    Hi, Overflow. I have an application which is supposed to convert a video via DirectShowSource. I have a checkbox which enables a button called "btnviewcrop" which shows a new form called crp.vb for cropping/shearing pixels off the video. Now, I have a Panel1 that I want to set as the owner (the video drawing surface) but when I set it to open, the application crashes (Error: Object reference not set to an instance of an object.) and I do not understand how to fix it. Here is my button code: Imports Microsoft.DirectX.AudioVideoPlayback Private Sub btnviewcrop_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnviewcrop.Click Me.ShowInTaskbar = False Me.Enabled = False crp.Show() Dim cropperv As Video cropperv.Owner = crp.preview cropperv.FromFile(labinputfile.Text, True) cropperv.Play() End Sub

  • Extracting DCT coefficients from encoded images and video

    - by misha
    Is there a way to easily extract the DCT coefficients (and quantization parameters) from encoded images and video? Any decoder software must be using them to decode block-DCT encoded images and video. So I'm pretty sure the decoder knows what they are. Is there a way to expose them to whomever is using the decoder? I'm implementing some video quality assessment algorithms that work directly in the DCT domain. Currently, the majority of my code uses OpenCV, so it would be great if anyone knows of a solution using that framework. I don't mind using other libraries (perhaps libjpeg, but that seems to be for still images only), but my primary concern is to do as little format-specific work as possible (I don't want to reinvent the wheel and write my own decoders). I want to be able to open any video/image (H.264, MPEG, JPEG, etc) that OpenCV can open, and if it's block DCT-encoded, to get the DCT coefficients. In the worst case, I know that I can write up my own block DCT code, run the decompressed frames/images through it and then I'd be back in the DCT domain. That's hardly an elegant solution, and I hope I can do better. Presently, I use the fairly common OpenCV boilerplate to open images: IplImage *image = cvLoadImage(filename); // Run quality assessment metric The code I'm using for video is equally trivial: CvCapture *capture = cvCaptureFromAVI(filename); while (cvGrabFrame(capture)) { IplImage *frame = cvRetrieveFrame(capture); // Run quality assessment metric on frame } cvReleaseCapture(&capture); In both cases, I get a 3-channel IplImage in BGR format. Is there any way I can get the DCT coefficients as well?

  • [iPhone] Play video not in full screen mode

    - by Kyo
    Hello, First, excuse my english :) I've read on apple developer website that video playback provides by the framework supports only full screen mode. I will need to develop an application where video can be played in reduce screen mode. I've see that Orange TV make something which looks like what i need to do. http://img218.imageshack.us/img218/1228/tvplayerorange.jpg The application is available on app store but you need to have a subscription to test this application. Whatever, to resume it, we can see video (tv stream video) in a reduce mode and if we click on the screen it switch to a full screen mode. So my question, what i want to do is possible (Orange TV made it) but i wonder the difficulty to make it. It seems that I have to make a video player. If it take a bunch of time, I tkink I will use Media Player Framework of iPhone even isn't the optimal solution for me. Feel free to ask me more details ;) Thank you for your answers.

  • Autoplaynig video/image gallery - with a catch

    - by Ran
    Looking for a (jQuery) video/image gallery to implement on my website, I've found many freely available option. However, I need one that, when in "autoplay" mode and gets to a video file, automatically plays an entire file, and only then moves on to the next image/video. Similar to what Picasaweb are doing when you ask to autoplay an online gallery of your images/videos. I have found, for example, this plugin: http://www.yoxigen.com/yoxview/. Notice that images 6 & 8 are actually video feeds, but when in autoplay mode, are treated just like any other image, i.e. - displayed for a few seconds then moves on to the next file... not what I need. Thank you in advance.

  • Persisting high score table in flash game without a network. (Featuring: HttpListenerException)

    - by bearcdp
    Hi everyone, this question is very programming-centric, but it's for a game so I figured I might as well post it here. I'm doing polishing work on a GGJ '11 game because it will be shown at an indie arcade tomorrow afternoon, and they're expecting our final build in the morning. We'd like to have a high score table that displays during attract mode, but since it's Flash (Flixel) it would require some networking, Mochi, or something to keep a record of these scores. Only problem is the machine we'd be running on probably won't have network access. As a quick solution, I thought I'd just write up a dinky little high score server in C#/.NET that could take basic GET requests for submitting scores and getting the score list. We're talking REAL basic, like blocking while waiting for an incoming request, run & forget console app, etc. There's no guarantee that our .swf won't get reloaded, and we'd like the scores to persist, so this server would pretty much exists to keep a safe copy of the scores that the game can add to and request, and occasionally the server will write the scores to a flat text file. But, HttpListener is giving me Error Code 87 'The parameter is incorrect.' Have any idea what I'm doing wrong? Or better yet, am I barking up the wrong tree and missing an obviously simpler solution? This is all I've got so far in my Main(): HttpListener listener = new HttpListener(); listener.Prefixes.Add("http://localhost:66666/"); listener.Start(); The exception happens at listener.Start(); and the stack trace is: at System.Net.HttpListener.AddAllPrefixes() at System.Net.HttpListener.Start() at WOSEBCE_ScoreServer.Program.Main(String[] args) in C:\Users\Michael\Documents\Visual Studio 2010\VS2010 Projects\WOSEBCE_ScoreServer\WOSEBCE_ScoreServer\Program.cs:line 24 at System.AppDomain._nExecuteAssembly(RuntimeAssembly assembly, String[] args) at System.AppDomain.ExecuteAssembly(String assemblyFile, Evidence assemblySecurity, String[] args) at Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly() at System.Threading.ThreadHelper.ThreadStart_Context(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean ignoreSyncCtx) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart()

  • ATI gpu (video accel, decode, encode, ATI Stream, DXVA)

    - by Shiki
    Okay its a long question title for sure. I'm looking for a new video card (yes,SU is not a page for that, but wait). I've been a loyal NVidia customer ever since, now using a 8600gts. Old but still somewhat good, its a bit slow though. I want an upgrade because 8600gts wont support better vdpau and new features. I checked out the prices and the documents, I would need a GTX260 card. Which costs ..well.. a lot. ATI performs much better for that price. (At least on every test it outperforms GTX260). However, as far as I know there is no gpu accel with ATI. The things you can use is DXVA only, no other method. Could you correct me out there? Will be there a gpu accel for ATI also? Or is there one available? (DXVA is not bad, but kinda slow compared to NVIdia's CUDA.) What about openCL? How does ATI support that? (I'm talking about the 5850 ATI card at the minute, I would buy that instead of the NVidia.)

  • Diff bios - corrupt video driver

    - by sfonck
    Hi, I'm using an Dell M90 Precision Laptop which has a NVidia Quadro FX 2500M graphics card and is running Windows XP. Laptop has been running fine - but a few weeks ago screen went 'white' - restarted computer- bios and startup screens show weird green dots and stripes, normal startup only shows a black screen... only VGA mode works to display something. I've been trying to remove and reinstall the correct drivers downloaded from Dell's website - no solution. I gave up and reinstalled XP - everything was working perfect again. 2 weeks later - again the white screen - tried everything again (flashin new bios also - nothing works) Reinstalled XP - everyhting was working again, so I made a DriveSnapShot of the partition. Today - again the 'white screen'. Ok, no problem ...I was thinking all I needed to do was to restore the DriveSnapShot backup... Few minutes later the backup is restored ... but guess what: video driver does not work correctly... As the DriveSnapShot restored the complete partition, as it was at the time everything was working perfectly, this would mean my driver problems are due to 'settings' in the bios or on the graphics-card itself + these 'settings' can get overridden by doing a new XP-install.... I'm out of options, can somebody help me to find a solution for this problem: Is there some way to backup and restore a bios after seeing some problems? Is there some way to know what is causing this problem like a bios diff utility? Thanks!

  • Obtaining YouTube video ID in a URL and inputting selected video ID into a URL

    - by Dave
    I've been having trouble in trying to figure this out. What I am trying to do is, obtain the ID of a video from YouTube, and input the 11 character ID into the css of a div of a specific id by using jquery. I know the URL for the thumbnail of any video, but I just need to be able to change the ID to display different video thumbnails. <script> $(document).ready(function() { function(data){ videoID = data.split('www.youtube.com/v/')[1].split('&amp')[0]; $("#304817679").append(videoID); }); $("#304817679").replaceWith("<div id=\"304817679\" style=\"background: url(http://img.youtube.com/vi/"+ $.function(data) +"/0.jpg) no-repeat middle; width: 15px; height: 150px;\"></div>"); }); }); </script> <div id="304817679"> <div style="display: none;"><object width="248" height="222"><param name="movie" value="http://www.youtube.com/v/vy90n2nNRKQ&amp;rel=0&amp;egm=0&amp;showinfo=0&amp;fs=1"></param><param name="wmode" value="transparent"></param><param name="allowFullScreen" value="true"></param><embed src="http://www.youtube.com/v/vy90n2nNRKQ&amp;rel=0&amp;egm=0&amp;showinfo=0&amp;fs=1" type="application/x-shockwave-flash" width="248" height="222" allowFullScreen="true" wmode="transparent"></embed></object></div> </div> Trying to explain this better, I want the 11 Character YouTube Video ID from the embedded code, and put it into the URL of the thumbnail (http://img.youtube.com/vi/"+ function(data) +"/0.jpg). Which, would then also replace the original div (div id="304817679"). Am I on the right track with my script? I'm entirely new to this, and I would appreciate some of the help that's offered here.

  • Hive Based Registry in Flash

    - by Psychic
    To start with I'll say I've read the post here and I'm still having trouble. I'm trying to create a CE6 image with a hive-based registry that actually stores results through a reboot. I've ticked the hive settings in the catalog items. In common.reg, I've set the location of the hive ([HKEY_LOCAL_MACHINE\init\BootVars] "SystemHive") to "Hard Drive\Registry" (Note: the flash shows up as a device called "Hard Drive") In common.reg, I've set "Flags"=dword:3 in the same place to get the device manager loaded along with the storage manager I've verified that these settings are wrapped in "; HIVE BOOT SECTION" This is where it starts to fall over. It all compiles fine, but on the target system, when it boots, I get: A directory, called "Hard Disk" where a registry is put A device, name called "Hard Disk2" where the permanent flash is Any changes made to the registry are lost on a reboot What am I still missing? Why is the registry not being stored on the flash? Strangly, if I create a random file/directory in the registry directory, it is still there after a reboot, so even though this directory isn't on the other partition (where I tried to put it), it does appear to be permanent. If it is permanent, why don't registry settings save (ie Ethernet adapter IP addresses?) I'm not using any specific profiles, so I'm at a loss as to what the last step is to make this hive registry a permanent store.

  • Understanding Flash SWC's imported into Flex Builder 3 and key framed animation

    - by Hank Scorpio
    I am trying to understand what is going on in a SWC that I am importing from Flash CS4 into Flex Builder 3. Specifically I am using a SWC supplied by a Designer as the animation for a custom preloader (a subclassed DownloadProgressBar). The issue I am trying to understand is, once the FlexEvent.INIT_COMPLETE is fired, I cleanup by removing the swc by running this : removeChild(myPreloader); myPreloader = null; though even after I have removed this (which is successful, as I have checked by comparing this.numChildren before and after the call) the key framed animation still continues to run (not visibly). This has been detected by the Designer placing a trace in the time line of the animation (in Flash). Can anyone tell me why is it, that even after I have removed the animation from the subclassed DownloadProgressBar, it still keeps running ? Also, is it standard practice when importing SWCs to manage the cleanup of resources from the Flash side of things (much like releasing memory in obj-c). I find it counter intuitive that removing the child from the Flex side does not stop the animation. Any clues to this would be greatly appreciated.

  • Flash video slooow in AIR 2 HTMLLoader component

    - by shane
    I am working on a full screen kiosk application in Flex 4/Air 2 using Flash Builder 4. We have a company training website which staff can access via the kiosk, and the main content is interactive flash training videos. Our target machines are by no means 'beefy', they are Atom n270s @ 1.6Ghz with 1Gb RAM. As it stands the videos are all but unusable when used from within the Air application, the application becomes completely unresponsive (100% cpu usage, click events take approx 5-10 seconds to register). So far I have tried: increasing the default frame rate from 24fps to 60. No improvement. nativeWindow.stage.frameRate = 60; running the videos in a stripped down version of my app, just a full screen HTMLLoader component pointed at the training website. No better than before. disabled hyper threading. The Atom CPU is split into two virtual cores, and the AIR app was only able to use one thread so maxed out at 50% CPU usage. Since the kiosk will only run the AIR app I am happy to loose hyper threading to increase the performance of the Air app. Marginal Improvement. The same website with the same videos is responsive if viewed in ie7 on the same machine, although Internet Explorer takes advantage of the CPU’s hyper threading. The flash videos are built with Adobe Captivate and from what I understand employee JavaScript to relay results back to the server. I will add more information about the video content asap as the training guru is back in the office later this week.

  • html5 vs flash - full comparison chart anywhere?

    - by iddqd
    So since Steve Jobs said Flash sucks and implied that HTML5 can do everything Flash can without the need for a Plugin, I keep hearing those exact words from a lot of People. I would really like to have a Chart somewhere (similar to http://en.wikipedia.org/wiki/Comparison_of_layout_engines_%28HTML5%29#Form_elements_and_attributes ) that I can just show to those people. Showing all the little things that Flash can do right now, that HTML5/Ajax/CSS is not yet even thinking about. But of course also the things that HTML5 does better. I would like to see details compared like audio playback, realtime audio processing, byte level access, bitmap data manipulation, webcam access, binary sockets, stuff in the works such as P2P technology (adobe stratus) and all the stuff I don't know about myself. Ideally with examples of what can be accomplished with, lets say Binary Sockets (such as a POP3 client) because otherwise it won't mean a lot to non-programmers since they will just say "well we can do without Binary Sockets". And ideally with some current benchmarks and some examples of websites that use this technology. I've searched the web and am surprised not to find anything. So is there such a comparison somewhere? Or does anybody want to create this and post it to Wikipedia? ;-)

  • Trouble creating a Java policy server for a simple Flash app

    - by simonwulf
    I'm trying to create a simple Flash chat application for educational purposes, but I'm stuck trying to send a policy file from my Java server to the Flash app (after several hours of googling with little luck). The policy file request reaches the server that sends a harcoded policy xml back to the app, but the Flash app doesn't seem to react to it at all until it gives me a security sandbox error. I'm loading the policy file using the following code in the client: Security.loadPolicyFile("xmlsocket://myhostname:" + PORT); The server recognizes the request as "<policy-file-request/" and responds by sending the following xml string to the client: public static final String POLICY_XML = "<?xml version=\"1.0\"?>" + "<cross-domain-policy>" + "<allow-access-from domain=\"*\" to-ports=\"*\" />" + "</cross-domain-policy>"; The code used to send it looks like this: try { _dataOut.write(PolicyServer.POLICY_XML + (char)0x00); _dataOut.flush(); System.out.println("Policy sent to client: " + PolicyServer.POLICY_XML); } catch (Exception e) { trace(e); } Did I mess something up with the xml or is there something else I might have overlooked?
