• Installing FFmpeg in Red Hat 5 without internet connection

  22 septembre 2014, par kobain8

  I am trying to install the last working version of FFmpeg over Red Hat 5 and the machine has no internet connection, so I have to bring all the packages and required dependencies in a USB. The problem I am having is to get everything I would need for it.

  I searched through Google to find some guide or documentation to hep me, but there is nothing valuable for me.

  The version I got install was FFmpeg 0.6, but it is too old for my purpose of grabbing with x11grab, so anyone has any suggestion in order to get install one of the last versions of FFmpeg.

  Thanks in advance, right now I need some light !!

  I can see the stream on the status page and my webcam light is on but it never loads. Does anyone know what I am doing wrong ?

• Ubuntu12.04 : libavformat header trouble when compiling C program

  30 mai 2013, par Juneyoung Oh

  My code is super simple, just include "avformat.h" and call "av_register_all".

  full code is below.

    1 #include 
  
    2 #include 
  
    3 #include 
  
    4 //#include <libavcodec></libavcodec>avcodec.h>
  
    5 #include <libavformat></libavformat>avformat.h>
  
    6 //#include "libavcodec/avcodec.h"
  
    7 //#include "libavformat/avformat.h"
  
    8 
  
    9 
  
   10 int main (int argc, char* argv[]){
  
   11         av_register_all();
  
   12 /*
  
   13         AVFormatContext* pFormatCtx;
  
   14         const char* filename = "/home/juneyoungoh/Videos/CON1234ID.ts";
  
   15 
  
   16         if(av_open_input_file(&amp;pFormatCtx, filename, NULL, 0, NULL) != 0)
  
   17         {
  
   18                 handle_error();
  
   19         }
  
   20 
  
   21         if(av_find_stream_info(pFormatCtx) &lt; 0)
  
   22         {
  
   23                 handle_error();
  
   24         }
  
   25 
  
   26         dump_format(pFormatCtx, 0, filename, 1);
  
   27 
  
   28         //av_get_audio_frame_duration();
  
   29 */
  
   30         return 0;
  
   31 }

  The problem is when I compile this in Terminal it show error.

  /tmp/ccvgpGjv.o: In function `main':
  
  getDuration.c:(.text+0x10): undefined reference to `av_register_all'
  
  collect2: ld returned 1 exit status

  my avformat.h file is in /usr/local/include/libavformat/avformat.h.

  Here is something I have already tried.

  1. gcc getDuration.c
  2. gcc -I/usr/local/include/ getDuration.c
  3. gcc -I/usr/local/include/libavformat/ getDuration.c
  4. gcc -L/usr/local/include/ getDuration.c
  5. gcc -L/usr/local/include/libavformat/ getDuration.c
  6. gcc getDuration.c -lavformat

  Give me the light of hope +_+
