• In the using directive "using Accord.Video.FFMPEG", FFMPEG does not exist in the name space

  15 septembre 2019, par StewartMetcalfe

  I am building an Azure Function in Visual Studio to convert a videos frames to images. I’m using the VideoFileReader class from Accord.Video.FFMPEG class. The code works on my machine but when trying to build this as an Azure Function Project, the using directive Accord.Video.FFMPEG errors.
  And subsequently the type VideoFileReader can not be found.

  I have tried re-installing the Accord, Accord.Video and Accord.Video.FFMPEG NuGet packages.

  using System.IO;
  
  using Microsoft.Azure.WebJobs;
  
  using Microsoft.Extensions.Logging;
  
  using Accord;
  
  using Accord.Video;
  
  using Accord.Video.FFMPEG;
  
  
  
  namespace ConvertVideo
  
  {
  
      public static class Function1
  
      {
  
          [FunctionName("Function1")]
  
          public static void Run([BlobTrigger("videos/{name}", Connection = "AzureWebJobsStorage")]Stream myBlob, string name, ILogger log)
  
          {
  
              log.LogInformation($"C# Blob trigger function Processed blob\n Name:{name} \n Size: {myBlob.Length} Bytes");
  
  
  
              //start a new videoFileReader
  
              using (var vFReader = new VideoFileReader())
  
              {
  
                  //open the video
  
                  vFReader.Open(name);
  
                  //get the framerate
  
                  double frameRate = vFReader.FrameRate.ToDouble();
  
                  //more code which converts a frame to jpg
  
              }
  
          }   
  
      }
  
   }

• ffmpeg returns "method SETUP failed : 404 Not Found"

  1er juillet 2019, par Alex

  We’re using ffmpeg (build ffmpeg-20190628-098ab93-win32-static) to take a snapshot from camera RTSP streams on a Win 10 system. On some cameras, we’re getting this error :

  [rtsp @ 06813ac0] method SETUP failed: 404 Not Found
  
  rtsp://username:password@example.com: Server returned 404 Not Found

  Here’s an example command we use :

  ffmpeg -y -i rtsp://username:password@example.com -vframes 1 -pix_fmt yuvj420p 
  
    -vf select='eq(pict_type\,I)' -q:v 1 _test.jpg

  However, VLC can load the same stream (we can’t use VLC, though) from the same machine. Additionally, we’ve opened the firewall to ffmpeg (it popped up the two firewall dialogs and we allowed it through).

  We’ve found posts on the DESCRIBE error but nothing on SETUP. Any help is appreciated. Thank you.

  Update : In VLC, that RTSP stream asks for credentials twice for some reason. Wondering if that’s the cause.
