• Dynamic way to add length to an html5 video

  6 septembre 2013, par Eric Paulsen

  I'm looking for a way to update the video length on an HTML5 video in the client side using Javascript.

  Example : I have a video clip loaded on the page that is 30 seconds long and I want to update it on the fly to be 45 seconds long.

  I had a look at the duration property of the HTMLMediaElement, but quickly discovered that the property was read only (source : https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement). I also stumbled upon this blog post, but my ideal solution would be to have one continuous clip. I could accomplish this on the server side using a tool like FFMPEG, but I'd rather not add an increase in load time for our users.

  Any suggestions ?

• Encode h264 automatically on nginx server

  18 février 2017, par Thinh Pham

  I have installed and configured my own streaming server using Nginx with rtmp module base on this tutorial https://www.vultr.com/docs/setup-nginx-on-ubuntu-to-stream-live-hls-video. I only use live application and record stream into flv file. And now I want to encode any new flv files in my VOD directory automatically to play it on my website. Is it possible to config it in my nginx.conf ? I have tried set record_suffix .mp4; in order to play it without encode but failed.
  Additional, exec ffmpeg -i is not work for me when I want to restream into mobile application.

• Using Windows named pipes with ffmpeg pipes (Doesnt work)

  25 octobre 2019, par Estr

  I’m trying to send audio and video RAW through c# pipes to FFMPEG, I’ve been reading and trying to follow what’s shown here : https://docs.microsoft.com/en-us/dotnet/api/system.io.pipes.namedpipeserverstream?view=netframework-4.8

  This a fragment of the code...

          NamedPipeServerStream p_1;
  
          NamedPipeServerStream p_2;
  
          p_1 = new NamedPipeServerStream("p_1", PipeDirection.Out, 1, PipeTransmissionMode.Byte);
  
          p_2 = new NamedPipeServerStream("p_2", PipeDirection.Out, 1, PipeTransmissionMode.Byte);
  
  
  
          p_1.WaitForConnection();
  
  
  
          p_2.WaitForConnection();

  .......

  I run this command in FFMPEG : ffmpeg.exe -i \.\pipe\p_1 -vcodec hevc -r 8 -f alaw -ar:a 16000 -ac:a 1 -i \.\pipe\p_2 o.mp4

  But the program stays on the line : p_2.WaitForConnection() ;

  How can I solve it ?
