How to encode video to use HTML 5 video tag? [closed]

I'm trying to use <video> tag feature. I've encoded my file with ffmpeg: ffmpeg -i 1.vob -f ogg -vcodec libtheora -b 800k -g 300 -acodec libvorbis -ab 128k out.ogv I've placed this text in index.html: <video src="out.ogv" controls></video> I've loaded this files to nginx document root and opened index.html in Firefox 3.5. I see the first frame, see controls, but can't play video. This video plays good even from my server. How should I encode video to view it in browser? UPD: If I start playing video from the middle, everything works fine.

How to design this ?

- by Akku

how can i make this entire process as 1 single event??? http://code.google.com/apis/visualization/documentation/dev/dsl_get_started.html and draw the chart on single click? I am new to servlets please guide me When a user clicks the "go " button with some input. The data goes to the servlet say "Test3". The servlet processes the data by the user and generates/feeds the data table dynamically Then I call the html page to draw the chart as shown in the tutorial link above. The problem is when I call the servlet it gives me a long json string in the browser as given in the tutorials "google.visualization.Query.setResponse({version:'0.6',status:'ok',sig:'1333639331',table:{cols:[{............................" Then when i manually call the html page to draw the chart i am see the chart. But when I call html page directly using the request dispatcher via the servlet I dont get the result. This is my code and o/p...... I need sugession as to how should be my approach to call the chart public class Test3 extends HttpServlet implements DataTableGenerator { protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { DataSourceHelper.executeDataSourceServletFlow(request, response, this , isRestrictedAccessMode() ); RequestDispatcher rd; rd = request.getRequestDispatcher("new.html");// it call's the html page which draws the chart as per the data added by the servlet..... rd.include(request, response);//forward(request, response); @Override public Capabilities getCapabilities() { return Capabilities.NONE; } protected boolean isRestrictedAccessMode() { return false; } @Override public DataTable generateDataTable(Query query, HttpServletRequest request) { // Create a data table. DataTable data = new DataTable(); ArrayList<ColumnDescription> cd = new ArrayList<ColumnDescription>(); cd.add(new ColumnDescription("name", ValueType.TEXT, "Animal name")); cd.add......... I get the following result along with unprocessed html page google.visualization.Query.setResponse({version:'0.6',statu..... <html> <head> <title>Getting Started Example</title> .... Entire html page as it is on the Browser. What I need is when a user clicks the go button the servlet should process the data and call the html page to draw the chart....Without the json string appearing on the browser.(all in one user click) What should be my approach or how should i design this.... there are no error in the code. since when i run the servlet i get the json string on the browser and then when i run the html page manually i get the chart drawn. So how can I do (servlet processing + html page drawing chart as final result) at one go without the long json string appearing on the browser. There is no problem with the html code....

How to make a composite Zend Form Element that includes a Dojo Field

- by Joe

I used the zendcast video to get me this far. The form is properly displayed. However, I need to change the display order box into a number box of zend dojo type. I cannot figure it out. Even help with examples would be great. <?php class My_View_Helper_CategoryDetailElement extends Zend_View_Helper_FormElement { protected $html = ''; public function CategoryDetailElement($name, $value = null, $attribs = null) { $type = $description = $displayOrder = $time = ''; if($value) { $type = $value->type; $description = $value->description; $displayOrder = $value->displayOrder; $time = $value->time; } $helper = new Zend_View_Helper_FormText(); $helper->setView($this->view); $helper_label = new Zend_View_Helper_FormLabel(); $helper_label->setView($this->view); $helper_select = new Zend_View_Helper_FormSelect(); $helper_select->setView($this->view); $helper_textarea = new Zend_View_Helper_FormTextarea(); $helper_textarea->setView($this->view); $this->html .= $helper_label->formLabel($name .

jQuery ajax multiline "script" response

- by Rendrik

I'm designing a template creation tool, which uses a jQuery Ajax request that posts parameters to a PHP file. The PHP does the actual generation of the template's HTML. // Send for processing. Expect JS back to execute. function generate() { $.ajax({ type: "POST", url: "generate.php", data: $('#genform :input').serialize(), dataType: "script", beforeSend: function() { $("#loading").html("<img src='images/loadbar.gif' />"); $("#loading") .dialog({ height: 80, width: 256, autoOpen: true, modal: true }); }, success: function(data) { $("#loading").dialog('close'); } }); } My trouble is that I have the ajax dataType: set to "script". Using this, the PHP file generates some jQuery dialogs for any errors which works nicely. However, after I generate the HTML, i'm having trouble passing it back. So I have probably 100 lines of generated HTML and javascript which i'd like to work with. In the PHP file, i've tried: echo('$("#result").html("'.$html.'");'); This does actually work if there are NO line breaks in $html. As soon as there are any line breaks, the Chrome debugger reports "gen.html:1 Uncaught SyntaxError: Unexpected token ILLEGAL". It's obvious that it's trying to eval the returned response headers, but is stopping at any line break. So, to be clear, when I pass $html back, if the contents are this: $html = "<div>hi there</div>"; It works fine (all of my error message dialogs are one line). But if it's: $html = "<div> hi there </div>"; It blows up. I'm really not sure how to get around this, or if there's a better way to go about it. It's important to me to keep the formatting so people can copy the HTML template. I may just break down and display the template file on the PHP page if I can't solve this, but I was really hoping to keep everything within the confines of the HTML page.

LAMP Stack Versioning -- Is there a website or version tracker source to help suggest the right versions of each part of a platform stack?

- by Chris Adragna

Taken singly, it's easy to research versions and compatibility. Version information is readily available on each single part of a platform stack, such as MySQL. You can find out the latest version, stable version, and sometimes even the percentage of people adopting it by version (personally, I like seeing numbers on adoption rates). However, when trying to find the best possible mix of versions, I have a harder time. For example, "if you're using MySQL 5.5, you'll need PHP version XX or higher." It gets even more difficult to mitigate when you throw higher level platforms into the mix such as Drupal, Joomla, etc. I do consider "wizard" like installers to be beneficial, such as the Bitnami installers. However, I always wonder if those solutions cater more to the least common denominator -- be all to many -- and as such, I think I'd be better to install things on my own. Such solutions do seem kind of slow to adopt new versions, slower than necessary, I suspect. Is there a website or tool that consolidates versioning data in order to help a webmaster choose which versions to deploy or which upgrades to install, in consideration of all the other parts of the stack?

Need help with DNS. Registrar is NS, Web Site at WinHost, Email at eHost

- by Leon

Need help moving a web site for a client, which I will call ClientABC. The web site is ClientABC.com, which is hosted at Rackspace, with their email hosted at eHost. We are transferring the site from Rackspace to WinHost and are keeping the email hosted at eHost. I would like the transfer to happen with little to no down time for the web site and email (email is most important). Current Config: Client owns domain and registrar is Network Solutions Domain name is managed by VendorX at Rackspace Web site is hosted on Rackspace servers Email is hosted at eHost Post-Move Config: Web site is hosted at WinHost Keep Email at eHost Here is my plan for the transfer: Copy the site files to WinHost and test to assure site is fully functional Set up the MX record in the WinHost account to point to eHost servers Change the DNS in Network Solutions from Rackspace to Winhost Questions: Will this work? What am I missing? Should I expect down time or any issues with email? I understand that there will be a period of time that traffic to the site is handled at both Rackspace and Winhost and that email traffic will be routed through both hosts as well. Will this cause issues? How will I know when the change is fully propagated and that Rackspace is out of the equation and WinHost is handling everything (so I can kill the Rackspace account) Thanks in advance!

I can't scroll my tilemap ... HELP!

- by Sri Harsha Chilakapati

Hello and I'm trying to make my own game engine in Java. I have completed all the necessary ones but I can't figure it out with the TileGame class. It just can't scroll. Also there are no exceptions. Here I'm listing the code. TileGame.java @Override public void draw(Graphics2D g) { if (back!=null){ back.render(g); } if (follower!=null){ follower.render(g); follower.draw(g); } for (int i=0; i<actors.size(); i++){ Actor actor = actors.get(i); if (actor!=follower&&getVisibleRect().intersects(actor.getBounds())){ g.drawImage(actor.getAnimation().getFrameImage(), actor.x - OffSetX, actor.y - OffSetY, null); actor.draw(g); } } } /** * This method returns the visible rectangle * @return The visible rectangle */ public Rectangle getVisibleRect(){ return new Rectangle(OffSetX, OffSetY, global.WIDTH, global.HEIGHT); } @Override public void update(){ if (follower!=null){ if (scrollHorizontally){ OffSetX = global.WIDTH/2 - Math.round((float)follower.x) - tileSize; OffSetX = Math.min(OffSetX, 0); OffSetX = Math.max(OffSetX, global.WIDTH - mapWidth); } if (scrollVertically){ OffSetY = global.HEIGHT/2 - Math.round((float)follower.y) - tileSize; OffSetY = Math.min(OffSetY, 0); OffSetY = Math.max(OffSetY, global.HEIGHT - mapHeight); } } for (int i=0; i<actors.size(); i++){ Actor actor1 = actors.get(i); if (getVisibleRect().contains(actor1.x, actor1.y)){ actor1.update(); for (int j=0; j<actors.size(); j++){ Actor actor2 = actors.get(j); if (actor1.isCollidingWith(actor2)){ actor1.collision(actor2); actor2.collision(actor1); } } } } } but the problem is that all the actors are working, but it just won't scroll. Help Please.. Thanks in Advance.

Is there any evidence that drugs can actually help programmers produce "better" code? [closed]

- by sytycs

I just read this quote from Steve Jobs: "Doing LSD was one of the two or three most important things I have done in my life." Also a quote from that article: He was hardly alone among computer scientists in his appreciation of hallucinogenics and their capacity to liberate human thought from the prison of the mind. Now I'm wondering if there's any evidence to support the theory that drugs can help make a "better" programmer. Has there ever been a study where programmers have been given drugs to see if they could produce "better" code? Is there a well-known programming concept or piece of code which originated from people who were on drugs? EDIT So I did a little more research and it turns out Dennis R. Wier actually documented how he took LSD to wrap his head around a coding project: "At one point in the project I could not get an overall viewpoint for the operation of the entire system. It really was too much for my brain to keep all the subtle aspects and processing nuances clear so I could get a processing and design overview. After struggling with this problem for a few weeks, I decided to use a little acid to see if it would enable a breakthrough, because otherwise, I would not be able to complete the project and be certain of a consistent overall design"[1] There is also an interesting article on wired about Kevin Herbet, who used LSD to solve tough technical problems and chemist Kary Mullis even said "...that LSD had helped him develop the polymerase chain reaction that helps amplify specific DNA sequences."

Boot failure randomly. Can someone help?

- by desgua

I often get stuck at the boot on battery. I can suspend and hibernate without any trouble (even on battery). If I plug the energy cable everything goes right most of the time (edited June 13). Adding "acpi=off" doesn't solve the issue. Disabling power save from LAN at BIOS doesn't solve this too. Memory test seems to be ok: I can even compile a kernel without a problem: Has someone a tip for this? (I have the same questions marks in my mind as the image shows if not more :-/ ) obs.: this is an upgraded installation from Natty alpha. edited I (May 22): I've installed a brand new final 11.04 and got the bug again. edited II (June 13): I thought it was solved but it is not. After spending eight days off, the same problem happened even with the power cable connected. I had to reboot about 6 times until success. edited III (June 14): I can boot (even with battery) if I disconnect the cable and take off the battery for a few seconds. This lead me to conclude that maybe something is kept into memory of some hardware. Maybe or maybe not related but I also have touchpad issues (jumps) with this machine. edited IV (June 25): I opened gconf-editor and went to apps gnome-power-manager and disabled everything possibly related to suspend or hibernate. No help. Also I grabbed a Fedora live usb pendrive and got the same problem: So I think it is a hardware problem related issue.

Would having an undergraduate certificate in Computer Science help me get employed as a computer programmer? [on hold]

- by JDneverSleeps

I am wondering how would employers perceive the Universtiy Certificate in Computing and Information Systems offered by Athabasca University (a distance education institution... The university is legit and accredited by the Government of Alberta, Canada). I already have a BSc in Statistics from University of Alberta (a classic brick and mortar public university in Alberta, Canada)...so I can state in my resume that I have a "university degree"..... Luckily, I was able to secure a very good employment in my field after the graduation from the U of A. The main reason why I am interested in taking the certificate program through Athabasca is because knowing how to program can increase the chance for promotion in my current job. I also believe that if something turns out bad in my current job and if I ever need to look for a new place to work, having the certificate in computer science will help me get employed as a computer programmer (i.e. my choice for the new job wouldn't be restricted to the field of Statistics). Athabasca University is claiming that the certificate program is meant to be equivalent to the undergraduate minor in computing science. I carefully looked at the certificate's curriculum and as far as I am concerned, the certificate program does have the same level of rigour as the undergraduate minor in Computer Science programs offered by other Canadian universities. I am also confident that the certificate program will get me to pick up enough skills/background to start a career as a computer programmer. The reasons why I am not 100% sure on getting the certificate is worth the tuition are: Athabasca University is a distance education institution (accredited by government but still) The credential that I will receive is "university certificate", not a "undergraduate degree" Do you think it's a good idea for me to pursue the certificate, given the two facts above? again, I already have my Bachelor's degree - although it is not in CS Thanks,

Extremely slow desktop and laggy. Need help with graphics driver

- by user171624

I am a fresh newbie Ubuntu user and I just installed my first Ubuntu 13.04 onto my HP Slate 2. I did a liveCD on my USB drive and installed everything perfectly fine...nice and smooth, not a trace of lag. Then I rebooted using Ubuntu itself on the computer, it was extremely slow and laggy. Icons or any buttons doesn't trigger right away, the performance of the entire thing looks like either 0.25 fps to 1 fps. My HP Slate 2 information: Processor: Intel Atom Z670 1.5Ghz Memory Ram: 2.0 GB Videocard: Intel GMA 600 (PowerVr SGX535) SolidStateDrive(SSD): 32GB I tried installing the intel linux graphics driver and it failed to install because it said I don't have any intel based graphics card. Well...I do as you see above. What can I do? I can't get on the internet on it, I'm using my primary computer (Windows 7) to do all the searchings and put the files onto the USB to move it over to my tablet. Simply...I don't get it...using liveCD on USB, it was all nice and smooth...then after the installation...BOOM! Slow, laggy, and etc. Can anyone help me? Thanks!

Is it justified to use project-wide unique function and variable names to help future refactoring?

- by kahoon

Refactoring tools (like ReSharper) often can't be sure whether to rename a given identifier when, for example refactoring a JavaScript function. I guess this is a consequence of JavaScript's dynamic nature. ReSharper solves this problem by offering to rename reasonable lexical matches too. The developer can opt out of renaming certain functions, if he finds that the lexical match is purely accidental. This means that the developer has to approve every instance that will be affected by the renaming. For example let's consider we have two Backbone classes which are used completely independently from each other in our application: var Header = Backbone.View.extend({ close: function() {...} }) var Dialog = Backbone.View.extend({ close: function() {...} }) If you try to rename Dialog's close method to for example closeAndNotify, then ReSharper will offer to rename all occurences of Header's close method just because they are the same lexically prior to the renaming. To avoid this problem, please consider this: var Header = Backbone.View.extend({ closeHeader: function() {...} }) var Dialog = Backbone.View.extend({ closeDialog: function() {...} }) Now you can rename closeDialog unambiguously - given that you have no other classes having a method with the same name. Is it worth it to name my functions this way to help future refactoring?

Here is the code: #include <stdio.h> #include <stdlib.h> int **CreatMatrix(int m,int n){ int **Matrix; int i; Matrix=(int**)malloc(m*sizeof(int*)); for(i=0;i<m;i++){ Matrix[i]=(int*)malloc(n*sizeof(int)); } return Matrix; } int main(){ int m,n; int **A; printf("Please input the size of the Matrix: "); scanf("%d%d",&m,&n); A=CreatMatrix(m,n); printf("Please input the entries of the Matrix, which should be integers!\n"); int i,j; for(i=0;i<m;i++){ for(j=0;j<n;j++){ scanf("%d",&A[i][j]); } } printf("The Matrix that you input is:\n"); for(i=0;i<m;i++){ for(j=0;j<n;j++){ printf("%3d ",A[i][j]); } printf("\n"); } for(i=0;i<m;i++) free(A[i]); free(A); } I have run it, and it works fine. But I am not sure if it is right? Can anyone help me debug it?

Help! Problem dual boot ubuntu windows8 (can't start ubuntu) [duplicate]

- by a35

This question already has an answer here: Installing Ubuntu on a Pre-Installed Windows 8 (64-bit) System (UEFI Supported) 5 answers EDIT: I know that there are many topics about dual boot ubuntu windows8, i have read them, my problem is that i cant boot ubuntu neither from HDD nor from live USB. I know about boot repairing, but how can I use it, If i cant boot ubuntu?? I heard about terrible problems with windows 8-linux dual boot, but I really need ubuntu because of school. I read many tutorials how to install ubuntu next to windows8, but despite that a problem accured. Here is what I have done. I have MSI GE60, windows(64bit) is running on mSATA SSD C drive. HDD is divided to two partitions for windows and I left there 50GB for ubuntu. I downloaded ubuntu 12.04.3desktop-amd64(64bit), created bootable USB using Universal USB Installer (recommended on Ubuntu site). I disabled USB legacy support (that Ubuntu could be installed in EFI mode- I was following instructions on Ubuntu site), and also Secure Boot (windows is now angry with me because I turned it off- when I start windows it informs me I should enable that). I inserted USB rebooted computer and chose install ubuntu, divided free 50GB space to swap(2000MB) and rest as ext4 main storage space for ubuntu. Installation passed normally, Ubuntu then asked me to reboot computer. After reboot windows 8 started. Now I can't start ubuntu. When I restart win8 to uefi there is possibility to boot ubuntu, but when I choose it, it crashes. When I choose try ubunfu from connected USB, nothing happend, still dark screed. What is wrong? Can you help me? I am in hurry to do it because of school. Thanks.

Tomcat IIS 7 Integration gives 503 errors on all requests.

- by Yvan JANSSENS

Hi, After many attempts to install Tomcat on IIS 7, I finally managed to get it working. At least I think so :-S. I finally got the 500 errors away, by setting the correct permissions. The only thing that doesn't work is ... serving stuff: neither regular stuff (like ASP, HTML files, or directory browsing) or Tomcat things work. Here are my configs: Worker.properties # The workers that your plugins should create and work with # worker.list=worker1 #------ DEFAULT ajp13 WORKER DEFINITION ------------------------------ #--------------------------------------------------------------------- # Defining a worker named ajp13 and of type ajp13 # Note that the name and the type do not have to match. # worker.worker1.port=8009 worker.worker1.host=127.0.0.1 worker.worker1.type=ajp13 URIWorkerMap.properties /|/*=worker1 # Exclude the subdirectory static: !/static|/*=worker1 # Exclude some suffixes: !*.html=worker1 !*.asp=worker1 Server.xml <?xml version='1.0' encoding='utf-8'?>   <Server port="8005" shutdown="SHUTDOWN">  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />  <Listener className="org.apache.catalina.core.JasperListener" />  <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />  <Listener className="org.apache.catalina.mbeans.ServerLifecycleListener" /> <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />  <GlobalNamingResources>  <Resource name="UserDatabase" auth="Container" type="org.apache.catalina.UserDatabase" description="User database that can be updated and saved" factory="org.apache.catalina.users.MemoryUserDatabaseFactory" pathname="conf/tomcat-users.xml" /> </GlobalNamingResources>  <Service name="Catalina">    <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />      <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />   <Engine name="Catalina" defaultHost="localhost">      <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/>  <Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false">     </Host> </Engine> </Service> </Server> http://localhost:8080 is working, I can view the apps and configure them there... I'm quite new to IIS 7, I used to work with IIS 6. Thanks in advance, Yvan

Can I use a MIME type declaration to get an HTML file to open in MS Word?

- by Toph

Bill James wrote: I was able to render an HTML page with the MIME type set to "application/msword", which caused the browser to spawn Word which imported the html just fine, allowing edits and saving just as if I'd output a real Word doc. That sounds great to me, but I haven't been able to get it to work in any browser (Chrome/FF/Safari/Opera/IE on Win7 running Word 2010 beta). I tried changing the MIME type in the HTTP headers of several pages via Tamper Data to application/msword, and I tried using the http-equiv meta tag <meta http-equiv="Content-type" content="application/msword"> on a local HTML file I tried opening from the browser, but neither appeared to have any effect. I don't really have a clue with regard to HTTP headers and MIME types generally, so - any tips? Many thanks!

Is it possible to intercept an HTML form post and do some processing before sending it to it's final

- by Brent

I'm trying to extend the functionality of an ASP.net application that I'm working with. For its logon page, it uses an html form to post to a dll to handle it's login logic. I'm wondering if there is any way to redirect that html POST to my C# code so that I can do some processing and then (and this is the part that I haven't figured out yet) POST it to the dll so that the regular logon logic can continue. I can make changes to the logon page, but the final step must be to do an HTML POST to the dll. I can't change that.

Help with Django localization--doesn't seem to be working. Nothing happens

- by alex

Can someone help me with Localization? I put {% trans "..." %} in my template, I filled in my django.po after running "makemessages". #: templates/main_content.html:136 msgid "Go to page" msgstr "¦~C~Z¦~C¦¦~B¦¦~L~G¦~Z" #: templates/main_content.html:138 msgid "Page" msgstr "¦~C~Z¦~C¦¦~B¦" #: templates/main_content.html:154 msgid "Next" msgstr "?" Then, I set LANGUAGES={} in my settings.py along with "gettext lambda": gettext = lambda s: s LANGUAGES = ( ('de', gettext('German')), ('en', gettext('English')), ('ja', gettext('Japanese')), ) Of course, I installed the LocaleMiddleware. I also set the request.session['django_language'] = "ja" How do I test that this is working? How do I see japanese on my site!?
