• how to use x264 dll in another project

  5 août 2014, par Hadi Rasekh

  enter code here I want to use x264 in my project. There is some line in the code said :

  /* Application developers planning to link against a shared library version of
* libx264 from a Microsoft Visual Studio or similar development environment
* will need to define X264_API_IMPORTS before including this header.
* This clause does not apply to MinGW, similar development environments, or non
* Windows platforms. */

  But I don’t get this line :
  define X264_API_IMPORTS before including this header

  We can create x264 dll by its configuration and make

      ./configure --enable-shared
  
      make

  but I can not use the dll in my Qt Project.

  I can make my own dll (in another code) and use it in the project.
  But when I start to use x264 dll in my project I get the following error :

      C:\DataHiding\SourceCode2\GUI\DataHiding\mainwindow.cpp:10: error:
  
      'pulldown_frame_duration' was not declared in this scope
  
      qDebug() << pulldown_frame_duration[1];
  
               ^

• Streaming MP4 frames to HTML5, what am I doing wrong ?

  5 septembre 2014, par mczarnek

  Currently I am generating a MP4 Bitstream using Intel’s Media SDK library, which uses ffmpeg underneath the covers. I can generate a mp4 file, and play it and it works.

  However, when I try to stream that mp4 across the network, it doesn’t play within the HTML5 video player, as tested within Chrome, Firefox, or IE.

  This much is sent back and forth across the network :

  Sent by Chrome:
  
  GET / HTTP/1.1
  
  Host: localhost:8085
  
  Connection: keep-alive
  
  User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/32.0.1700.102 Safari/537.36

  Accept: */*
  
  Accept-Language: en-US,en;q=0.8
  
  Range: bytes=0-
  
  
  
  From my video player:

  Server: Microsoft-HTTPAPI/2.0
  
  Date: Thu, 09 Jan 2014 17:28:14 GMT
  
  Content-type: video/mp4

  After this, I send a newline, and all the video frames, one after another, while listening to see if I receive anything back from the browser.

  Then nothing happens. Any suggestions to get this playing video ? Thank you !
