问题 hey, i've got a wpf application that have a doubleanimation used for scrolling text and images (scrollbar) from the left side of the screen, to the right, and a movie playing, in the same window. everytime a video ends, and a new video loads, the doubleanimation get stuck/hangs for a second, then it continues normally. i assume it's the control blocking the ui thread while loading the video. i've tried to create a seperate UI thread for the scrolling bar but i didn't solve the problem. i've

问题 Is there a way to embed a youtube video into a MediaElement and save the video? I know that once you have an object inside your application you can have some sort of control over it(I think). If I'm correct, is it possible to save the youtube video once it is embedded inside the MediaElement? Thanks. 回答1: Youtube videos are not available as files, as they are streams. that makes it a bit hard to save them (Actually you can, JDownloader does that, but that's infringement of YT terms), but for

问题 I am currently developing an UWP youtube player and i am having some big trouble with playing the actual video. I am using this to play a youtube video in a media element: using MyToolkit.Multimedia; var url = await YouTube.GetVideoUriAsync(youtubeid, YouTubeQuality.Quality1080P); var YoutubePlayer = new MediaElement(); YoutubePlayer.Source = url.Uri; It used to work just fine for about a month, but now it just... doesn't. It gets the right video URI (the mp4), i also tried with the

问题 I’m using MediaElement for playing videos and BackgroundAudioPlayer for playing audio. Here is a case. I’m playing remote audio via BackgroundAudioPlayer. Then I want to play video and before MediaElement begins playing video I’m calling BackgroundAudioPlayer.Close as suggested in BackgroundAudioPlayer best practices.

问题 I just want to change the position of the gif in the MediaElement , so when i don't hover it with the mouse it should display a certain image of the GIF (the selected position) and when i move the cursor on the MediaElement the GIF should start playing from position zero. But i am not able to change the position of the GIF at all. It starts playing and i can pause it, but setting position and the stop() method have no influence at all. XAML Code: <MediaElement x:Name="mediaElement" Source="C:

问题 In my WPF project I have created a view that includes several MediaElements playing videos. Sometimes, anywhere between one or all of the MediaElements will fail to play the video assigned to them, and will instead show a black rectangle, or not appear at all. The MediaFailed event does not occur when this happens. The MediaOpened event DOES get raised on all the MediaElements, even when they do not play the video. I have installed the latest drivers for my graphics card and that has had no

问题 When I run my Silverlight app, this code doesn't play a video at all: <MediaElement Source="winvideo-201DataGridPreview.wmv" AutoPlay="True" AudioStreamIndex="2" Margin="10" Height="200" Width="200"/> From all of the examples I can find of MediaElement, it seems to be the correct syntax, etc. Is there anything I'm forgetting? 回答1: Edward, based on your XAML check: 1) that the WMV file is in the appropriate encoding format, 2) that the WMV file is located alongside where your XAP file is (I'd

问题 string url = re["response"][0]["url"].ToString(); MediaElement mm = new MediaElement(); mm.Source = new Uri(url,UriKind.RelativeOrAbsolute); mm.AutoPlay = true; mm.Volume = 0.7; mm.Play(); But no changes, the adudio not starts.How I can resolve this? 回答1: You need to add your MediaElement to your VisualTree before playing it, since you're creating it in the codebehind. For example, assuming you have LayoutRoot and that your url is correct, this should work. string url = re["response"][0]["url
