Get images thumbnail file paths

由 南楼画角 提交于 2019-12-01 06:31:08
I'm trying to get the thumnail paths , not the bitmaps objects. When I query for these, some of the thumbnail paths are null for some reason. (I have 1028 thumbnail images in my device, the cursor length is indeed 1028, but still returning nulls) I know there are 1028 thumbnail images because I checked. Here's my code: String[] projection = {MediaStore.Images.Thumbnails._ID}; // Create the cursor pointing to the SDCard cursor = this.getContentResolver().query( MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, projection, // Which columns to return null, // Return all rows null, MediaStore

Error '!dat' trying to set the (null) audio devices' sample rate

I am trying to play an audio clip (using AVAudioPlayer) and a video clip (using MPMoviePlayerController), both of which were working. I then checked the files into SVN and pulled them down on another Mac. Now when I run the app (iPad app) when it tries to play either the audio or video, both give the error: Error '!dat' trying to set the (null) audio devices' sample rate Figuring that SVN corrupted the files, (even though the Mac's QuickLook will play them fine), I replaced them with the versions on the Mac where they still work. However I am still getting the error. All code is exactly the

CSS3 Media Queries 实现响应式设计

在 CSS2 中，你可以为不同的媒介设备（如屏幕、打印机）指定专用的样式表，而现在借助 CSS3 的 Media Queries 特性，可以更为有效的实现这个功能。你可以为媒介类型添加某些条件，检测设备并采用不同的样式表。 　　例如，你可以把用于大屏幕上显示的样式和用于移动设备的专用样式放在一个样式文档中，这样，在不改变文档内容的情况下，不同的设备可以呈现不同的界面外观。阅读这篇文章学习 CSS3 Media Queries 的基本功能和国外使用 CSS3 的 Media Queries 特性的优秀网站案例。 CSS3 Media Queries 看下这个 在线演示 ，调整你的浏览器窗口尺寸，看看它的变化。 Max Width 下面的样式会在可视区域的宽度小于 600px 的时候被应用。 1 2 3 4 5 @media screen and ( max-width : 600px ) { .class { background : #ccc ; } } 如果你想链接到一个单独的样式表，把下面的代码放在<head>标签里。 1 <link rel= "stylesheet" media= "screen and (max-width: 600px)" href= "small.css" /> Min Width 下面的样式会在可视区域的宽度大于 900px 的时候被应用。 1 2

with just a plain html and js file, how can i force a link to an mp3 to download instead of just play?

i have a link to a media file such as an mp3, and i want it to get downloaded when the user clicks on it, instead of just having the file get played. the page i have in mind is just a plain static html page. any ideas? In order to make that happen you need to send a header with Content-disposition: attachment; filename=fname.ext header in your favorite language before sending the file. Without knowing the specifics such as what language and what control you have over your server configuration I cannot give you more detailed instructions. You cannot do it with just html and javascript however.

How to create a IDirect3DSurface from an IBuffer or byte array in UWP

由 梦想与她 提交于 2019-12-01 00:02:36
I want to create a video from a few RenderTargetBitmap s in UWP. I am doing that by using MediaClips . From RenderTargetBitmap i can get an IBuffer or byte array of pixels. To create a MediaClip I need either an image file or an IDirect3DSurface . Creating an image just to create a clip is very expensive, so I thought of using IDirect3DSurface . How can I do this? I have tried this: RenderTargetBitmap renderTargetBitmap = new RenderTargetBitmap(); await renderTargetBitmap.RenderAsync(RenderedGrid, 100, 100); IBuffer pixels = await renderTargetBitmap.GetPixelsAsync(); var values = Enum
