• FFmpeg - Libavcodec - unable to compile, errors on files not found, but files are there

  3 octobre 2020, par QRrabbit

  This is less about C++, and more about specific compiling avcodec and avformat as those are used inside FFmpeg. I'm trying to compile for the first time ffmpeg project code. All the linking has been resolved, and the program errors our.

  


  I'm writing my first program - attempt at avformat libraries inside my C++ code. Linker errors on this line :

  This is the content of my *libavcodec.pc file, and it has an entry of conflicts : which lists all of the items that clang cannot find, I don't know if those are linked somehow. I found a source pointing that similar error appears if I had other forks of ffmpeg, but I do not.

  I don't have experience in cmakefile, I can paste it here if needed.
Any help is greatly appreciated, because I'm stuck for the past several days.

  


  I have two CMakeLists :

  


  cmake_minimum_required(VERSION 3.17)
project(ffmpeg_01)

set(CMAKE_CXX_STANDARD 14)

add_subdirectory(lib/glfw)
add_subdirectory(lib/FFmpeg)

add_definitions(-DGL_SILENCE_DEPRECIATION)

if(APPLE)
    list(APPEND EXTRA_LIBS
            "-framework OpenGL"
            )
elseif(LINUX)
    list(APPEND EXTRA_LIBS
            "-lGL -lGLU -lX11")
endif()

add_executable(ffmpeg_01 src/main.cpp src/load_frame.cpp)
target_link_libraries(ffmpeg_01 FFmpeg glfw ${EXTRA_LIBS})


  


  and the interface for FFmpeg under FFmpeg sub directory :

  


  cmake_minimum_required(VERSION 3.17)
project(FFMPEG)

find_package(PkgConfig REQUIRED)

pkg_check_modules(AVCODEC    REQUIRED IMPORTED_TARGET libavcodec)

add_library(FFmpeg INTERFACE IMPORTED GLOBAL)

  I also tried adding the following block below target_link_libraries, but no difference on compilation outcome :

  


  target_link_options(FFmpeg INTERFACE

• Merge Audio with Video is not working probably using android 9 & 8

  22 juillet 2021, par ebdaa app

  I am trying to use the following code to merge audio with video,

  


      cmd = "-stream_loop -1 -i " + videoUri + " -i " + audioPath + " -shortest -map 0:v:0 -map 1:a:0 -y " + videoOutputPath;

    long executionId = FFmpeg.executeAsync(cmd, new ExecuteCallback() {

        @Override
        public void apply(final long executionId, final int returnCode) {
            if (returnCode == RETURN_CODE_SUCCESS) {
                playVedio(videoOutputPath);
            } else {
                ErrorLogger();
            }
        }
    });


  


  as you can see the above code does the following things :

  


  

  1. replace audio in video with new one.

  


  2. loop the video until the new audio ends.

  


  


  everything works perfectly when trying to run the code using both android 11 and 10 , however , when try to use android 9 or 8 , the first and the last 2 seconds of the new audio will be trimmed in the generated video and I am not able to know why

  


  I am using 4.4 version of the mobile-ffmpeg

  


   com.arthenica:mobile-ffmpeg-full:4.4


  


  please find the log from android 8/9

  In "mergeVideos" function the "returnCode" it return value "1" when i look in the package code

  


  getState() async {
    try {
      return _platform
          .abstractSessionGetState(this.getSessionId())
          .then((state) {
        switch (state) {

          case 2:
            return SessionState.failed;
          case 3:
          default:
            return SessionState.completed;
        }
      });
    } on PlatformException catch (e, stack) {
      print("Plugin getState error: ${e.message}");
      return Future.error("getState failed.", stack);
    }
}


  


  Which mean its keep running but in my code it does not wait until complete merging

  


  how can i fix that ??!

  


  but i think my problem is in command(concat)

  


  
-i /storage/emulated/0/Movies/VID_20240512_115128.mp4 -i /storage/emulated/0/Movies/VID_20240512_115116.mp4 -filter_complex "[0:v][1:v]concat=n=2:v=1:a=0[outv]" -map "[outv]" -y /storage/emulated/0/merged_video_2024513_122719.mp4


  


  (This is my command when i run the code) ??
