• Using JNI in my project and geeting error "Fatal signal 11 (SIGSEGV) at 0x000000ec (code=1) "

  9 juillet 2012, par Rahul Upadhyay

  I read so many post on this que but was unable to find out my problem. I am using JNI ina my project, developing with FFMPEG library. When i start decoding video using ffmpeg it gives me an error Fatal signal 11 (SIGSEGV) at 0x000000ec (code=1) and force stop.

  Using Nexus, and it uses maxMemory : 67108864

  i know heap Size by applying this code

  Runtime rt = Runtime.getRuntime();
  
  long maxMemory = rt.maxMemory();
  
  Log.v("onCreate", "maxMemory:" + Long.toString(maxMemory));

• Troubles setting up FFMPEG with Code::Blocks

  14 juillet 2014, par David Norgren

  I’m trying to compile this in Code::Blocks with MinGW :

  extern "C" { // also tried without this
  
      #include <libavcodec></libavcodec>avcodec.h>
  
  }
  
  
  
  int main()
  
  {
  
      AVCodec* codec;
  
      avcodec_register_all();
  
      return 0;
  
  }

  The header file contains the AvCodec struct and void avcodec_register_all(void) ; but I still get undefined reference to `avcodec_register_all’. It doesn’t complain about the AvCodec pointer.

  My project build options :

  • Linker Settings->Link Libraries : C :\Libs\ffmpeg\lib\avcodec.lib
  • Search Directories->Compiler : C :\Libs\ffmpeg\include
  • Search Directories->Linker : C :\Libs\ffmpeg\lib

  Any ideas why I get this error ?

• How to deploy external library along with function source code to firebase ?

  2 octobre 2017, par Yizhou Yan

  I am new to the firebase. I am doing a project which requires using ffmpeg to process video.

  What I know about ffmpeg is that it runs on cmd. If I want to use ffmpeg to process video on my local computer in node.js, I need to install two things :

  I first need to download the ffmpeg source code from its website, and set the system path variable so that I can run ffmpeg cmd in any directory. By doing this, I am now able to run ffmpeg in cmd to process video.

  Second, install the ffmpeg module via npm. By doing this, I am now able to write code in node.js(or javascript ?) and uses functions that ffmpeg module provided to process video.

  Now I want to do it with firebase. what I know about the firebase is that I am only allowed to write functions in node.js(or javascript ?) and deploy the functions to firebase server which could be trigger by events.

  I also know that if I run npm install --save ffmpeg. in the function folder, it installs the module and --save builds the dependency for me. Here the question comes. Where should I put the ffmpeg source code file and deploy it along with the ffmpeg module and my js function source code to the firebase ? and do I need to configure the ffmpeg source file(like setting the system path variable) ? Thank you in advanced !
