• cpu.c : Merge ia32 and x86_64 CPU info functions

  27 février 2017, par Erik de Castro Lopo

  cpu.c : Merge ia32 and x86_64 CPU info functions
  After the removal of the OS SSE detection stuff ia32_cpu_info()
  
  and x86_64_cpu_info() became very similar. Merging them makes
  
  sense.

• Video files are not opening for sample applications in Info Sphere Streams

  10 mars 2017, par Pavan Kumar

  I am new to IBM Info Sphere Streams, I read an article which says IBM Info Sphere streams is capable of doing Image processing. After some research I got to know that, we have to install OpenCV and FFMpeg lybraries with its dependecies. I have installed all of them and tried sample applications. I can run applications which contains Images as input, but when it comes to processing with videos it’s not working. I am unable to use x11viewer operator as well. I am getting the following error while working with sample videos.

  (Streams com.ibm.streamsx.opencv::X11Viewer operator:7889): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed
  
  28 Feb 2017 14:00:34.672 [7889] ERROR #splapptrc,J[0],P[0],vid0,spl_pe M[PEImpl.cpp:process:1270]  - CDISR5079E: An exception occurred during the processing of the processing element. The error is: Unable to open camera {0}. 

  I did not install any GPU device drivers here but when I used the following commands I am getting results like below,

  [streamsadmin@streamsqse output]$ lspci | grep VGA
  
  00:0f.0 VGA compatible controller: VMware SVGA II Adapter
  
  
  
  [streamsadmin@streamsqse output]$ find /dev -group video
  
  /dev/fb0
  
  /dev/dri/card0
  
  /dev/dri/renderD128
  
  /dev/dri/controlD64
  
  /dev/agpgart

  and

  glxinfo | grep -i vendor
  
  server glx vendor string: SGI
  
  client glx vendor string: Mesa Project and SGI
  
  OpenGL vendor string: VMware, Inc

  My doubt here is, whether I have installed GPU Drivers properly or do I need to install them again ? Can anyone help me to resolve this issue.

  And I am unable to open those videos by using any player as well.

• FFMPEG - error opening key info file

  15 mars 2017, par Hoang Nam

  everything run normal.

  but i meet problem when i move file "480.mp4.key" and file "480.mp4.keyinfo" into other directory such as : /usr/local/WowzaStreamingEngine/keys/auto_scan/testhh/2/123/480.mp4.keyinfo
  I also change key directory in file keyinfo

  After that i run

  ffmpeg -i 480.mp4 -hls_time 10 -hls_key_info_file 480.mp4.keyinfo output.mp4.m3u8 ffmpeg -i output/testhh/2/123/480.mp4 -hls_time 10 -hls_key_info_file /usr/local/WowzaStreamingEngine/keys/auto_scan/testhh/2/123/480.mp4.keyinfo output/testhh/2/123/480.mp4.m3u8

  Error :
