• ASP.NET MVC - Converting Video Format From Email Attachment Scanner

  24 juillet 2018, par BenHayward

  We have a Quartz scheduler that scans the company email account every 60 seconds, and will process those emails accordingly. Any attachments are stored in a byte array.

  Video attachments need to be converted to an MP4 and then back to a byte array to be stored in the DB ; I am trying to use FFMPEG (fflib) to complete this, however I’m having trouble figuring out how it can be done with a byte array as the source - the company have stated that this conversion must be done before it enters the database.

  Is the conversion of a byte array possible using the Process Class to access the FFMPEG CLI ?

  Here is the code I currently have, just using local file locations (using fflib ffmpeg library).

   public IList<documentstoreattachment> AddDocumentsToDocumentStore(IList<fileattachment> documentsToStore, Guid personId, IList<documentattributedto> documentAttributes)
  
          {
  
              var storedDocuments = new List<documentstoreattachment>();
  
  
  
              foreach (var documentToStore in documentsToStore)
  
              {
  
                  try
  
                  {
  
                      if (IsExtensionAllowed(documentToStore.AttachmentName))
  
                      {
  
  
  
                          if (documentToStore.MimeType == "mpeg")
  
                          {
  
                              Job2Convert job = new Job2Convert()
  
                              {
  
                                  pszSrcFile = @"..\..\Amigo Loans 2018 Advert MPG.mpg",
  
                                  pszDstFile = @"C:\Users\ben.hayward\Desktop\Amigo Loans 2018 Advert MPG.mp4",
  
  
  
                                  pszDstFormat = "mp4",
  
                                  pszAudioCodec = "aac",
  
  
  
                                  nAudioChannels = 2,
  
                                  nAudioBitrate = -1,
  
                                  nAudioRate = -1,
  
  
  
                                  pszVideoCodec = "h264",
  
  
  
                                  nVideoBitrate = -1,
  
                                  nVideoFrameRate = -1,
  
                                  nVideoFrameWidth = -1,
  
                                  nVideoFrameHeight = -1
  
  
  
                              };
  
  
  
                              _sut.ConvertFile(job);
  
  
  
                          }
  
  
  
                          storedDocuments.Add(AddDocumentToDocumentStore(documentToStore.AttachmentName, documentToStore.ByteArray, documentToStore.MimeType, personId, documentAttributes));
  
                      }
  
                      else
  
                      {
  
                          Logger.WarnFormat("AddDocumentsToDocumentStore: File extension not allowed for file name: {0}, person id: {1}", documentToStore.AttachmentName, personId);
  
                      }
  
                  }
  
                  catch (Exception e)
  
                  {
  
                      #region Error
  
  
  
                      Logger.Error(String.Format("There was a problem saving the document to the document store. The file name was {0}, person id: {1}",
  
                          documentToStore.AttachmentName, personId), e);
  
  
  
                      #endregion
  
                  }
  
              }
  
  
  
              return storedDocuments;
  
          }
  
  </documentstoreattachment></documentattributedto></fileattachment></documentstoreattachment>

  Thank you in advance.

• Building a livestream page where the user will input an rtsp streaming source through an ip address

  7 décembre 2020, par Antax Md

  I am building a livestream page where the streaming source is streamed through rtsp. Currently, I am using ffmpeg to convert the incoming rtsp stream to a .m3u8 file and it is played back on the webpage through HLS.

  


  The problem i am trying to solve now, is loading an rtsp stream based on the user's input. How do i go about solving this ? It is a requirement to able to view the stream on iOS and android.
The ffmpeg command :

  


  ffmpeg -i "rtsp://10.193.79.185:5554" -hls_time 3 -hls_wrap 10 "C:\wamp64\www\hls\output.m3u8"


  


  Code of what I have at the moment that loads a hard coded rtsp stream

  


  &#xA;&#xA;  &#xA;      <code class="echappe-js">&lt;script src=&quot;https://cdn.jsdelivr.net/npm/hls.js@latest&quot;&gt;&lt;/script&gt;&#xA;      &#xA;          
  RTSP Stream
  &#xA;                &#xA;                &#xA;
  Start
  &#xA;                &#xA;
  
  &#xA;      &#xA;&#xA;      &lt;script&gt;&amp;#xA;        if(Hls.isSupported()) &amp;#xA;        {&amp;#xA;            var video = document.getElementById(&amp;#x27;video&amp;#x27;);&amp;#xA;            var mystring = &quot;http://192.168.43.79/hls/output.m3u8&quot;;&amp;#xA;            var hls = new Hls({&amp;#xA;              debug: true&amp;#xA;            });&amp;#xA;            hls.loadSource(mystring);&amp;#xA;            hls.attachMedia(video);&amp;#xA;            hls.on(Hls.Events.MEDIA_ATTACHED, function() {&amp;#xA;            video.muted = true;&amp;#xA;            video.play();&amp;#xA;        });&amp;#xA;        }&amp;#xA;        // hls.js is not supported on platforms that do not have Media Source Extensions (MSE) enabled.&amp;#xA;        // When the browser has built-in HLS support (check using `canPlayType`), we can provide an HLS manifest (i.e. .m3u8 URL) directly to the video element throught the `src` property.&amp;#xA;        // This is using the built-in support of the plain video element, without using hls.js.&amp;#xA;        else if (video.canPlayType(&amp;#x27;application/vnd.apple.mpegurl&amp;#x27;)) {&amp;#xA;            video.src = &amp;#x27;http://192.168.43.79/hls/output.m3u8&amp;#x27;;&amp;#xA;            video.addEventListener(&amp;#x27;canplay&amp;#x27;,function() {&amp;#xA;            video.play();&amp;#xA;          });&amp;#xA;        }&amp;#xA;      &lt;/script&gt;&#xA;  &#xA;&#xA;
