• How to know if x264 uses multiple processors Windows

  3 décembre 2013, par fessy

  I have Linphone open source application that uses x264 encoder. By default it runs on one thread :

  x264_param_t *params= ..... 
  
  params->i_threads=1;

  I added ability to use all processors :

  long num_cpu=1;
  
  SYSTEM_INFO sysinfo;
  
  GetSystemInfo( &sysinfo );
  
  num_cpu = sysinfo.dwNumberOfProcessors;
  
  params->i_threads=num_cpu;  

  The question is how do I know that during video streaming x264 runs on (in my case) 4 processors ?

  Because from Task Manager -> Performance -> CPU usage history doesn't clear.

  I use windows 7

  Thanks,

• I cant install jmf-2_1_1e-windows-i586 on windows 7 32 bit.

  I am trying to install Java Media Framework in windows 7 to use to develop a video and audio conferencing desktop application but the response i get is, its not compatible when i install with troubleshoot option. Its windows 7 32 bit. Although Java Media Framework is old i prefer Java Media Framework over Free Media for Java because it has lot of documentation online and in books. My question is How can i make jmf-2_1_1e-windows-i586 compatible with the my OS.

  I tried installing without troubleshoot option and the installation starts but after unpacking the package it remains in the running processes but never continues.

  I'm testing ClipBucket on a Windows XP system, and ClipBucket (open source video share) uses FFmpeg to convert videos. The final command it executes is (i changed it a little to make it compatible with the current FFmpeg) :

  D:\ffmpeg-snapshot-git\ffmpeg\ffmpeg.exe -i C:
  
  \wamp\www\chclip/files/conversion_queue/1352973741c353c.mp4 -f flv -vcodec libx2
  
  64 -pre normal -r 25 -s 426x240 -aspect 1.775 -vf "pad=10:20:30:40:yellow"  -ac
  
  odec libfaac -ab 128000 -ar 22050 C:\wamp\www\chclip/files/videos/13540939451e18
  
  4.flv 2> C:\wamp\www\chclip/files/temp/13540939461c124.tmp 2>&1

  And this is the response I get :

  How can I get this libx264 working in Windows ?
