  lavf/mov : don't read outside frag_index bounds
  Potentially fixes :
  
  https://bugs.chromium.org/p/chromium/issues/detail?id=786269#c1
  In theory, the crash can be triggered by an invalid stream that has

  • [DH] libavformat/mov.c

• How to link FFmpeg libraries with CMake in windows

  4 juillet 2021, par ldall03

  I'm new to CMake and not very familiar with how linking/compiling works. I am on windows 10 using MinGW in CLion. As the title says I want to use FFmpeg libraries in my c++ code. I downloaded the source code from : https://ffmpeg.org/download.html (Download Source Code button). I unzipped it and put the libavcodec library in my project. Here is my project structure :

  


  project
   \-- cmake-build-debug
   \-- src
      \-- vendor
         \-- libavcodec
   \-- main.cpp
   \--CMakeLists.txt


  


  Here is my main.cpp file :

  


  extern "C" {&#xA;#include "libavcodec/avcodec.h"&#xA;}&#xA;&#xA;#include <iostream>&#xA;&#xA;int main(int argc, char *argv[]) {&#xA;    std::cout &lt;&lt; "Hello World\n";&#xA;    return 0;&#xA;}&#xA;&#xA;</iostream>

  


  And my CMakeLists.txt file :

  


  cmake_minimum_required(VERSION 3.19)
project(VidShare)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_PREFIX_PATH  "C:/Qt/6.1.1/mingw81_64/lib/cmake")

find_package(Qt6Widgets REQUIRED)

set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_AUTOUIC ON)

add_executable(VidShare main.cpp)
include_directories(src src/vendor)
target_link_libraries(VidShare Qt6::Widgets Qt6::Core Qt6::Gui)


  


  Ignore the Qt stuff it works fine.

  


  And well when I build I get this error message :

  


  fatal error: libavutil/avconfig.h: No such file or directory
 #include "libavutil/avconfig.h"


  


  I've seen that I had to run a configure script in the FFmpeg main file but I'm on windows so I can't really do that. I don't know if I have to use other kinds of libraries or if I downloaded the wrong thing... I am really at lost here. There is probably a better or more convenient way of doing what I want but I could not find many resources on it... Help would be appreciated :)
