  • Can't correctly stream x264 video to mobile via RTSP

    - by Andrew
    Hello! I'm trying to stream video compressed with x264 and NeroAAC and hinted with MP4Box. When i'm playing it with VLC player streaming works fine, as expected. When i'm trying to open URL with my HTC Hero, it switches to player mode, then starts "loading video" animation, then after some time it shows "unable to connect to server". Sample movies provided with DSS streamed fine regardless bitrate. I tried few encoding options, but always the same result. I suspect nocabac and level=11 but it didn't changed nothing. Is there some more specific encoding options for such type? Thank You!

  • SQL join to grab data from same table via intermediate table

    - by Sergio
    Hi Could someone help me with building the following query. I have a table called Sites, and one called Site_H. The two are joined by a foreign key relationship on page_id. So the Sites table contains pages, and the Site_H table shows which pages any given page is a child of by having another foreign key relation back to the site table with a column called ParentOf. So, a page can be have another page as a parent. Other data is stored in the Site_H table such as position etc, hence why it is separated out. I would like a query that returns the details of a page along with the details of its parent page. I just cant quite think about how to structure the SQL. Thanks

  • Selecting first instance of class but not nested instances via jQuery

    - by DA
    Given the following hypothetical markup: <ul class="monkey"> <li> <p class="horse"></p> <p class="cow"></p> </li> </ul> <dl class="monkey"> <dt class="horse"></dt> <dd class="cow"> <dl> <dt></dt> <dd></dd> </dl> <dl class="monkey"> <dt class="horse"></dt> <dd class="cow"></dd> </dl> </dd> </dl> I want to be able to grab the 'first level' of horse and cow classes within each monkey class. But I don't want the NESTED horse and cow classes. I started with .children, but that won't work with the UL example as they aren't direct children of .monkey. I can use find: $('.monkey').find('.horse, .cow') but that returns all instances, including the nested ones. I can filter the find: $('.monkey').find('.horse, .cow').not('.cow .horse, .cow .cow') but that prevents me from selecting nested instances on a second function call. So...I guess what I'm looking for is 'find first "level" of this descendant'. I could likely do this with some looping logic, but was wondering if there is a selector and/or some combo of selectors that would achieve that logic.

  • Accessing HttpRequest from Global.asax via a page

    - by Polymorphix
    I'm trying to get a property (ImpersonatePersonId) from a page in global.asax but get a HttpException saying 'Request is not available in this context'. I've been searching for some documentation on where in the pipeline the request is accessible, but as far as I can see all Microsoft can produce of documentation is one-liners like "PostRequestHandlerExecute: Occurs when the ASP.NET event handler finishes execution." which really doesn't give me much... I've tried placing the call in both Pre and PostRequestHandlerExceute but with the same result. I wonder if anyone with experience in this would be so kind as to tell me where the Request object is available. My code from global asax is below. ICanImpersonate page = HttpContext.Current.Handler as ICanImpersonate; ImpersonatedUser impersonatePerson = page != null ? page.ImpersonatePersonId : null; Response.Filter = new TagRewriter(Response, new TagProcessor(Context, impersonatePerson).Process); What I want to do is rewrite some HTML based on some request parameters.

  • Parallel processing via multithreading in Java

    - by Robz
    There are certain algorithms whose running time can decrease significantly when one divides up a task and gets each part done in parallel. One of these algorithms is merge sort, where a list is divided into infinitesimally smaller parts and then recombined in a sorted order. I decided to do an experiment to test whether or not I could I increase the speed of this sort by using multiple threads. I am running the following functions in Java on a Quad-Core Dell with Windows Vista. One function (the control case) is simply recursive: // x is an array of N elements in random order public int[] mergeSort(int[] x) { if (x.length == 1) return x; // Dividing the array in half int[] a = new int[x.length/2]; int[] b = new int[x.length/2+((x.length%2 == 1)?1:0)]; for(int i = 0; i < x.length/2; i++) a[i] = x[i]; for(int i = 0; i < x.length/2+((x.length%2 == 1)?1:0); i++) b[i] = x[i+x.length/2]; // Sending them off to continue being divided mergeSort(a); mergeSort(b); // Recombining the two arrays int ia = 0, ib = 0, i = 0; while(ia != a.length || ib != b.length) { if (ia == a.length) { x[i] = b[ib]; ib++; } else if (ib == b.length) { x[i] = a[ia]; ia++; } else if (a[ia] < b[ib]) { x[i] = a[ia]; ia++; } else { x[i] = b[ib]; ib++; } i++; } return x; } The other is in the 'run' function of a class that extends thread, and recursively creates two new threads each time it is called: public class Merger extends Thread { int[] x; boolean finished; public Merger(int[] x) { this.x = x; } public void run() { if (x.length == 1) { finished = true; return; } // Divide the array in half int[] a = new int[x.length/2]; int[] b = new int[x.length/2+((x.length%2 == 1)?1:0)]; for(int i = 0; i < x.length/2; i++) a[i] = x[i]; for(int i = 0; i < x.length/2+((x.length%2 == 1)?1:0); i++) b[i] = x[i+x.length/2]; // Begin two threads to continue to divide the array Merger ma = new Merger(a); ma.run(); Merger mb = new Merger(b); mb.run(); // Wait for the two other threads to finish while(!ma.finished || !mb.finished) ; // Recombine the two arrays int ia = 0, ib = 0, i = 0; while(ia != a.length || ib != b.length) { if (ia == a.length) { x[i] = b[ib]; ib++; } else if (ib == b.length) { x[i] = a[ia]; ia++; } else if (a[ia] < b[ib]) { x[i] = a[ia]; ia++; } else { x[i] = b[ib]; ib++; } i++; } finished = true; } } It turns out that function that does not use multithreading actually runs faster. Why? Does the operating system and the java virtual machine not "communicate" effectively enough to place the different threads on different cores? Or am I missing something obvious?

  • ORDER BY column_name help (via link in HTML table view) (PHP MySQL

    - by Derek
    My output for my table in HTML has several columns such as userid, name, age, dob. The table heading is simply the title of the column name, I want this to be a link, and when clicked, the selected column is sorted in order, ASC, and then DESC (on next click). I thought this was pretty straight forward but I'm having some difficulty. So far, I have produced this, and no output is taken, apart from the URL works by displaying 'users.php?orderby=userid' <?php if(isset($_GET['orderby'])){ $orderby = $_GET['orderby']; $query_sv = "SELECT * FROM users BY ".mysql_real_escape_string($orderby)." ASC"; } //default query else{ $query_sv = "SELECT * FROM users BY user_id DESC"; } ?> <tr> <th><a href="<?php echo $_SERVER['php_SELF']."?orderby=userid";?>">User ID</a></th> Hoefully if I get this working, I can sort the users by D.O.B. next also using the same principles. Does anyone have any ideas?

  • Assigning a selector via SEL type?

    - by fuzzygoat
    I just spotted the following in an online tutorial. It showed 001 as a method for assigning a selector, however I could not get this to work. Am I right in thinking that 001 is not right and 002 is the correct way, or am I doing something wrong with 001? // 001 SEL mySel = [self something]; // 002 SEL mySel = @selector(something); . -(void)something { NSLog(@"YAY"); } Gary

  • Reload external javascript after asynchronous postback via UpdatePanel

    - by Protector one
    I have an external javascript on my page, e.g. something like: <script src="http://foo.com/script.js" type="text/javascript"></script> and an UpdatePanel somewhere. The script writes some content, and does this from within an anonymous javascript function in the js file. I.e., there is something like this in the script: (function(){document.write('content');})(); Whenever the UpdatePanel is updated through asynchronous postback, everything the script did (or any javascript on my page, for that matter) is made undone. For normal javascript, I would just use: Sys.WebForms.PageRequestManager.getInstance().add_endRequest(myFunction) to redo all that, but since the function in the script source file is anonymous and called upon definition, I'm SOL! Any ideas? Note: the external js source is from another domain and its content is out of my control.

  • resizing images with imagemagick via shell script

    - by jml
    Hi there, I don't really know that much about bash scripts OR imagemagick, but I am attempting to create a script in which you can give some sort of regexp matching pattern for a list of images and then process those into new files that have a given filename prefix. for example given the following dir listing: allfiles01.jpg allfiles02.jpg allfiles03.jpg i would like to call the script like so: ./resisemany.sh allfiles*.jpg 30 newnames*.jpg the end result of this would be that you get a bunch of new files with newnames, the numbers match up, so far what i have is: IMAGELIST=$1 RESIEZFACTOR=$2 NUMIMGS=length($IMAGELIST) for(i=0; i<NUMIMGS; i++) convert $IMAGELIST[i] -filter bessel -resize . RESIZEFACTOR . % myfile.JPG Thanks for any help... The parts that I obviously need help with are 1. how to give a bash script matching criteria that it understands 2. how to use the $2 without having it match the 2nd item in the image list 3. how to get the length of the image list 4. how to create a proper for loop in such a case 5. how to do proper text replacement for a shell command whereby you are appending items as i allude to. jml

  • Include a database file with Android application via Eclipse

    - by fatcat1111
    How can I instruct Eclipse to copy a file from my Android solution to an emulator, as part of Run/Debug? I have a small database, stored in Assets, that needs to accompany the application. Thus far I have simply copied the file myself using DDMS but would prefer to have it automatically included. The project properties allow me to specify some aspects of the build, e.g. the build order and which libraries should be included, but I don't see anything about simply copying a file.

  • Checkbox values to varchar via Spring

    - by iowatiger08
    I am trying to get a varchar message from a database to display the selected values of a checkbox field in a jsp for patient's medication's dosage frequency. The possible values will be saved in comma-delimited string in the varchar. For most form fields there is simply a one form value to one database field ratio, but in this case, I am needing to merge the values that would come as a string[] into the comma-delimited string and then when retrieving that record for that medication of that patient, display the selected values from the comma-delimited string as selected from the selectableDosageFrequencyList. You assistance in this is greatly appreciated as I am not sure what I am missing here. In the application context, I created the list of possible values as part of the ServiceBean. <property name="selectableDosageFrequencyList"> <set> <value>On an empty stomach</value> <value>Every other day</value> <value>4 times daily</value> <value>3 times daily</value> <value>Twice daily</value> <value>At bedtime</value> <value>With meal</value> <value>As needed</value> <value>Once daily</value> </set> </property> This is set up in the flow as requestscope. <view-state id="addEditMedication" model="medication"> <on-render> <set name="requestScope.selectableDosageFrequencyList" value="memberService.buildSelectableDosageFrequencyList(patient)" /> </on-render> ... <transition on="next" to="assessment" > <evaluate expression="memberService.updateMedication(patient, medication)" /> </transition> </view-state> I have helper methods in the memberService that need to be executed when the form is init and then when the form is completed. //get the form fields selected and build the new string for db public String setSelectedDosageFrequency(String [] dosageFrequencies){ String frequencies = null; if (dosageFrequencies != null){ for (String s : dosageFrequencies){ frequencies = frequencies + "," + s; } } return frequencies; } //get value from database and build selected Set public LinkedHashSet<String> getSelectedDosageFrequencyList(String dosageFrequency){ String copyOfDosages =dosageFrequency;//may not need to do this LinkedHashSet<String> setofSelectedDosageFrequency = new LinkedHashSet<String> (); while (copyOfDosages!= null && copyOfDosages.length()>0){ for (String aFrequency: selectableDosageFrequencyList){ if (copyOfDosages.contains(aFrequency)){ setofSelectedDosageFrequency.add(aFrequency); if (!copyOfDosages.equals(aFrequency) && copyOfDosages.endsWith(aFrequency)){ copyOfDosages.replaceAll(","+aFrequency, ""); }else if (!copyOfDosages.equals(aFrequency) && copyOfDosages.contains(aFrequency=",")){ copyOfDosages.replaceAll(aFrequency+",", ""); }else copyOfDosages.replaceAll(aFrequency, ""); copyOfDosages.trim(); } } } return setofSelectedDosageFrequency; } The Medication class that backs the form will have a variable for dosage-frequency as a string. private String dosageFrequency; The jsp I currently am doing this. <div class="formField"> <form:label path="dosageFrequency">Dosage Frequency</form:label> <ul class="multi-column double" style="width: 550px;"> <form:checkboxes path="dosageFrequency" items="${selectableDosageFrequencyList}" itemLabel="${selectableDosageFrequencyList}" element="li" /> </ul> </div>

  • Stop scrolling to ID when opening jQuery Modal via URL

    - by markedup
    I need to be able to open an ID'd jQuery UI Modal on a page when that modal's ID is passed in the page's URL. For example: http://mysite.com/visit.html#directions #directions is an ID'd DIV at the very bottom of the page, right before the closing BODY element. It's instantiated as a jQuery UI dialog on page load, then I'm running a function to check the current URL for the modal's ID. If the URL contains the modal's ID, the modal is opened. Here's what my auto-open function looks like: function autoOpenModal() { if ( document.location.href.indexOf('#') ) { var uriParts = document.location.href.split('#'); var hashID = '#' + uriParts[1]; if ( $(hashID) && $(hashID).hasClass('dialog')) { $(hashID).dialog('open'); } } } The problem I'm having is that the browser is automatically scrolling down to the ID at the very bottom of the page before the modal is opened. So when the user closes the modal they're at the bottom of the page (which seems "broken" to me). Can anyone tell me how I stop the browser from auto-scrolling down to the ID please? I've had a look at event.preventDefault() but without success; I'm not sure where or how to use it in the event chain.

  • Reducing a set of non-unique elements via transformations

    - by Andrey Fedorov
    I have: 1) a "starting set" of not-necessarily-unique elements, e.x. { x, y, z, z }, 2) a set of transformations, e.x. (x,z) = y, (z,z) = z, x = z, y = x, and 3) a "target set" that I am trying to get by applying transformations to the starting set, e.x. { z }. I'd like to find an algorithm to generate the (possibly infinite) possible applications of the transformations to the starting set that result in the target set. For example: { x, y, z, z }, y => x { x, x, z, z }, x => z { z, x, z, z }, x => z { z, z, z, z }, (z, z) => z { z, z, z }, (z, z) => z { z, z }, (z, z) => z { z } This sounds like something that's probably an existing (named) problem, but I don't recognize it. Can anyone help me track it down, or suggest further reading on something similar?
