• Nginx allow only my domain to access a video url

  4 septembre 2019, par Bruno F

  i’m setting up a web server that contains live video streaming embed into the html5 video tag. My workflow is to grab the rtsp video from an ip camera, decode it to a HLS format using ffmpeg and send the video to my server.
  Nginx allows access to the video through a url, which I put in my video tag as a source.

  Everything works perfectly, the only problem is that anyone can access the URL of the video and put that URL on their website without my permission.

  Is there any way to only allow my domain to access, and block for example www.domain2.com to put it into their video tag or other framework thath they use ? i’m think Nginx can do the job maybe.

  Here are the codes of Nginx and my html in case is needed.

  HTML :

  <video class="video-js vjs-default-skin vjs-big-play-centered vjs-fluid" controls="controls" preload="none">
  
  <source src="//mydomain.com/live/stream.m3u8" type="application/x-mpegURL"></source>
  
  </video>

  Nginx :

  location /live {
  
              types {
  
                      application/vnd.apple.mpegurl m3u8;
  
              }
  
              limit_conn addr 5;
  
              alias /home/stream;
  
              add_header Cache-Control no-cache;
  
              add_header 'Access-Control-Allow-Origin' '*';
  
      }

  Many thanks guys !

• how to parse Access Unit in h.264

  24 septembre 2014, par user2406774

  I am working in a project that needs to cut some Access units in H.264 raw elementary stream,for example remove 4 access units and play the remaining video .

  For this I took Access unit Delimiter (NAL Unit Type:9) as boundary for Access Unit and cut the video but the video ended with packet loss. But if I took Sequence parameter set (NAL Unit type :7) as boundary, resultant video playing without any packet loss.
  Some one please help me how to solve this issue : where shall I cut the video ?

• Can you access a picked StorageFile from its Path ? - UWP

  17 août 2020, par HooptyDoopty

  I need to be able to access a file from it's path in a UWP application.

  


  The file is first selected by the user using OpenFilePicker. I then need to pass this file on to an FFmpeg wrapper that sets its input from a file path. Currently, I get access denied errors for any file that is outside the apps local storage (as expected).

  


  FileOpenPicker filePicker = new FileOpenPicker();
filePicker.ViewMode = PickerViewMode.Thumbnail;
filePicker.FileTypeFilter.Add("*");


var file = await filePicker.PickSingleFileAsync();


FFMpegArguments
   .FromInputFiles(file.Path.ToString())


  


  Is there a way to retain the apps permission to this file when it is accessed by a path string (file.Path.ToString()) rather then a storage file instance ? Have been looking into FutureAccessList but that seems to only provide another storage file instance later rather then allow for path access to the same file. I'd like to not enable broad file system access as I only need access to a single file that has already been picked by the user.

  


  Thanks !
