overlay

问题 I'm trying to add overlay images/text on top of mp4 videos inside an Android application. Most solutions point to FFmpeg (or appunits AndroidFFmpeg) but isn't stable and very complicated to maintain. Is there a native way to do this using the Android SDK? (MediaCodec? MediaMuxer?) Thank you, Ori 回答1: There are two ways to understand your question: You want to temporarily superimpose video with additional information . This can be done using the standard layout procedure: Use the built-in

问题 I'm having trouble getting the heights on my divs to match up. I need them to match the heights of the div with the most content - which is normally easy BUT I'm doing this with overlays that also contain more text. I can't do it with fixed heights or widths because I need the layout to be responsive. The cells need to basically be col-md-2 with the tallest height as the text wraps, it would be more like a square, col-sm-6 would be long and narrow, and col-xs-12 would also be long and narrow.

问题 I'm using Fancybox v2.0.5 and can't figure out how to fade in the overlay slowly. The openSpeed parameter only controls the content fade speed, but I want the entire thing fading in at that speed. Here is my call: $(".fancybox").fancybox({ prevEffect : 'none', nextEffect : 'none', fitToView : false, autoSize : true, openEffect : 'fade', openSpeed : 1500, helpers : { overlay : { opacity : 0.9, css : { 'background-color' : '#fff' } } } }); I'm thinking one of the callbacks that fire before the

问题 I want to implement a help overlay for my app. It should look like this: How do I create a help overlay like you see in a few Android apps and ICS? final Dialog dialog = new Dialog(this); dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT)); dialog.setContentView(R.layout.coach_mark); dialog.setCanceledOnTouchOutside(true); //for dismissing anywhere you touch View masterView = dialog.findViewById

问题 I want to use TinyMCE editor in a overlay dialog.. Is that possible? I have latest version TinyMCE and Jquery Tools Overlay. JQuery Tools Overlay: http://flowplayer.org/tools/demos/overlay/index.html 回答1: I ran into a few issues with this, apparently tinymce doesn't play nicely with hidden elements, and gets confused when you write over elements it's attached to. Anyway, got it to work by using overlay's hooks, making a synchronous js call (this is the crucial part), and detaching tinymce

问题 GWT RPC is a mechanism provided by gwt to communicate between client and server. Also there's a Request Builder, through which you can connect to the server. Which mechanism would you recommend for a gwt based app, and please state the reasons to do so as well.. 回答1: I'd think GWT RPC is most likely the way to go.

问题 Here's my code: I've got a flash slideshow on my page. I've used thickbox for login but when someone clicks on the login, the flash overlays thickbox. I've managed to solve the problem on Firefox, but nothing seems to work on Internet Explorer. 回答1: You need to use one of the following attributes in order to get Flash to sit "within" the DOM rather than over it. wmode=transparent -or- wmode=opaque Comes with the disadvantage of breaking a number of features. 回答2: spender is correct, but he

问题 I'm trying to show/hide some GeoJSON data on an overlay layer. I've the data as an object, but not at some server. If I use the overlay type 'geoJSON', I'm getting a Eror: A base layer must have an url How do I show/hide my data using the overlay show/hide?
