FFmpeg avutil.lib unresolved external symbol
2 août 2022, par Serei'm trying to use FFmpeg with visual sudio 2022 .NET 6 through an MSVC project.
I followed this tutorial : https://www.youtube.com/watch?v=qMNr1Su-nR8&ab_channel=HakanSoyalp.
I mean I have configureg Include (.h) file, library (.lib) files and dynamic (.dll) file copied into bin folder.
If I call for example the avformat_alloc_context() method inside the avformat.lib all work rightly, if I call for example av_file_map(...) inside the avutil.lib the compiler give me an error :
LNK2019 unresolved external symbol "int __cdecl av_file_map ...
But the avutil.lib is linked !!!
The same happen if I call other methods inside avutil.lib module.


Thanks for help...


Code :


extern "C"
{
 #include <libavformat></libavformat>avformat.h>
 #include <libavutil></libavutil>file.h> // av_file_map
}

int ConvertJPEGtoNALs(int argc, char* argv[])
{
 AVFormatContext* fmt_ctx = NULL;
 AVIOContext* avio_ctx = NULL;
 uint8_t* buffer = NULL, * avio_ctx_buffer = NULL;
 size_t buffer_size, avio_ctx_buffer_size = 4096;
 char* input_filename = NULL;
 int ret = 0;
 struct buffer_data bd = { 0 };
 if (argc != 2) {
 fprintf(stderr, "usage: %s input_file\n"

 "accessed through AVIOContext.\n", argv[0]);
 return 1;
 }
 input_filename = argv[1];

 //av_register_all(); //!deprecated
 /* slurp file content into buffer */
 ret = av_file_map(input_filename, &buffer, &buffer_size, 0, NULL);
 /* fill opaque structure used by the AVIOContext read callback */
