问题 I use NReco.Data in my Asp.NetCore Application to make db-calls, because I don't want to use EF and DataTable isn't supported yet. Now I need to call a StoredProcedure and get Multiple RecordSets (or Dictionarylists).

问题 I have a sub which gets the duration of a video file. Async Sub GetDuration(folder As String) Dim ffP As New FFProbe Dim vInfo As MediaInfo Dim totalSecs As Double = Await Task.Run(Function() vInfo = ffP.GetMediaInfo(filep) If vInfo.Duration.TotalSeconds < 10 Thread.Sleep(20000) End If Return vInfo.Duration.TotalSeconds End Function) When I run this on a short video (less than 10 seconds), it sleeps the application for 20 seconds, as expected. On another tab in the browser, however, I run it

问题 I found the NReco.VideoInfo library to be the best option and simpler 1] Find the NReco.VideoInfo library in NuGet Package Manager and import it in your project 2] After that import the namespace "using NReco.VideoInfo" 3] Add the below line of code into the method. var ffProbe = new FFProbe(); var videoInfo = ffProbe.GetMediaInfo(blob.Uri.AbsoluteUri); return videoInfo.Duration.TotalMilliseconds; here you can see some other option 回答1: Why don't you use the windows media player to solve this
