Possible Duplicate: silverlight media player with frame counter We want to know whether we can get frame number? 回答1: If you know the frames per second (FPS) then you multiply the FPS times the position in the media.

问题 I am using media element to render video in WPF. All videos are working fine except H.264 videos. They have some stuttering problem while they are rendered on screen. My machine configuration is much more than the recommended requirement to play for this video. Another surprising fact is that the video renders perfectly fine when I play this in Window Media Player or any other player. Any solution or any alternative to MediaElement? 回答1: WPF does not support H.264 videos 回答2: You can try my

问题 As far as I know Windows Media Player 10 is the minimum requirement for WPF MediaElement to work. What is a decent way to programmatically (from .NET) check if WMP is present, and its version? 回答1: The method I used in my installer is to check this registry value: HKLM Software\Microsoft\MediaPlayer\PlayerUpgrade PlayerVersion The PlayerVersion value will be set to a string like "10,0,0,0". (Note that commas, not periods, are used to separate the numbers.) You need to extract the first number

问题 This concerns WPF. The problem is that my MediaElement (actually a GIF) doesn't show up at runtime (so I only get an empty screen), even though it shows perfectly in the design mode. Before citing the code I note the following: The GIF-file in question has been added to the solution. Its BuildAction property is set to Resource (I've checked). When I replace the MediaElement by an Image element (and either use the same GIF-file or replace that source-file by a .png file), the image/GIF does
