live

问题 I am trying to display live images from my 1394 camera. Currently my code is able to obtain images in a loop from the camera and I was looking for any quick GUI that will update dynamically (as a separate thread). I can do this in PyQt maybe using QThreads but is there any recommendation or faster way of doing this?? Here's my code #Loop capturing frames from camera for frame in range(1,500): print 'frame:',frame TIME.sleep(1) #capture frame every second image_binary = pycam.cam

问题 I'm working on a live wallpaper that incorporates some water ripple effects on touching the screen but I'm a little stuck. Would it be better to create multiple images and loop through them to create a ripple animation or would it be better to distort the bitmap a bit before I place it on the canvas? This is a video of a very nice ripple effect done through OpenGL. I don't have any experience yet with OpenGL and was wondering if it is still possible to create a 2D water effect on the live

问题 Mouseup doesn't fire on scroll bar for elements dynamically added (except Firefox): CSS: #dBox { height: 100px; width: 230px; overflow - y: auto; } HTML: <input type="text" id="s"> JQuery: $(function() { $('#s').focus(function() { var $dbox = $('<ul id="dBox"></ul>'); for (i = 0; i < 10; i++) $dbox.append('<li>' + i + '</li>'); $(this).after($dbox); $dbox.bind("mouseup", function() { alert('in: '); //console.log ('in: '); }); }); }); // OR LIKE THIS $('#s').focus(function() { var $dbox = $('

I have to make an iOS app which plays a live video stream from a camera. I know that the iPhone only supports Live HTTP stream, but unfortunately it comes with a delay of about 6-10 seconds, which is far from my needs - I need a real time view. MJPEG stream is also not an option, because it generates a huge

问题 I'm working on a project, in which when I keep pressing on the min/plus button without hovering off the picture with the .live() method, the function works. In the case of .on() method the function does not work. How can I fix this issue, so it works for .on() method as well? Here is an example of what I’m referring too (I fixed the error in this example, but I was using the .on method wrong). 回答1: You're not using it correctly. The replacement for .live() is $(document).on() with the event

问题 I want to understand how exactly to interpret bubbling. Does it mean going up the HTML code hierarchy or something else? Secondly, I was going through an example and I could not understand the last part where it says The P-based click handler listens for the click event and then prevents it from being propagated (bubbling up) What does this mean? 回答1: return false; will prevent "bubbling". It's used to stop default actions like checking a checkbox, opening a select, a click, etc. To stop

问题 I've a problem in my project. I would like to launch a process, 7z.exe (console version). I've tried three different things: Process.StandardOutput.ReadToEnd(); OutputDataReceived & BeginOutputReadLine StreamWriter Nothing works. It always "wait" for the end of the process to show what i want. I don't have any code to put, just if you want my code with one of the things listed upthere. Thanks. Edit: My code: process.StartInfo.UseShellExecute = false; process.StartInfo.RedirectStandardOutput =

问题 I want to add a class to any DOM element that is on the page now or in the future that has a specified class and meets some criteria so for some pseudo code $('.location').live('load',function(){ if($(this).find('input:first').val().substr(0,1) == "!"){ $(this).addClass('hidden')} }); of course this does nothing EDIT NOTE this does not work either $('.location').live('load',function(){ alert('adding location'); }); 回答1: jQuery's live() feature is just subset of the livequery plugin, which is

问题 I'm using the following jquery code to show a contextual delete button only for table rows we are hovering with our mouse. This works but not for rows that have been added with js/ajax on the fly... Is there a way to make this work with live events? $("table tr").hover( function () {}, function () {} ); 回答1: jQuery 1.4.1 now supports "hover" for live() events, but only with one event handler function: $("table tr").live("hover", function () { }); Alternatively, you can provide two functions,

问题 I don't have my own Flash Media Server. I can however use the Highwinds CDN. They run FMS on their CDN. When you schedule a live event, Highwinds gives you two urls: the "server" and "stream name". Examples: server: rtmp://fli003.am4.hwcdn.net/XXXX/ definst stream name: fli/00000-streamname?encoderuser=XXX&encoderpassword=YYY These two urls can be pasted into the Flash Media Live Encoder application to stream the live event. The respective field names in Flash Media Live Encoder are "FMS URL"
