  • Bundle FFmpeg with Qt6 application using CMake

    10 janvier 2023, par AliOsm

    I'm trying to bundle FFmpeg with my Qt6 application that uses CMake as build system on Mac OS system (Apple chip). I tried the following :

    


    FetchContent_Declare(
    ffmpeg
    GIT_REPOSITORY https://github.com/FFmpeg/FFmpeg.git
    GIT_TAG        n5.1.2
)

FetchContent_MakeAvailable(ffmpeg)

include_directories(
    "/Volumes/ieasybooks/taqtie/build-repo-Qt_6_4_0_for_macOS-Debug/_deps/ffmpeg-src/libavutil"
    "/Volumes/ieasybooks/taqtie/build-repo-Qt_6_4_0_for_macOS-Debug/_deps/ffmpeg-src/libavcodec"
    "/Volumes/ieasybooks/taqtie/build-repo-Qt_6_4_0_for_macOS-Debug/_deps/ffmpeg-src/libavformat"
)

target_link_libraries(
    taqtie
    PRIVATE
    "/Volumes/ieasybooks/taqtie/build-repo-Qt_6_4_0_for_macOS-Debug/_deps/ffmpeg-src/libavutil/libavutil.h"
    "/Volumes/ieasybooks/taqtie/build-repo-Qt_6_4_0_for_macOS-Debug/_deps/ffmpeg-src/libavcodec/libavcodec.h"
    "/Volumes/ieasybooks/taqtie/build-repo-Qt_6_4_0_for_macOS-Debug/_deps/ffmpeg-src/libavformat/libavformat.h"
)


    


    But when I include FFmpeg libraries like this :

    


    extern "C" {
#ifndef __STDC_CONSTANT_MACROS
#define __STDC_CONSTANT_MACROS
#endif
#include 
}


    


    I got the following error :

    


    main.cpp:6:10: In included file: 'libavutil/avconfig.h' file not found


    


    I spent like 1 month on this issue and I can't find any solution. I even asked ChatGPT :)

    


    Do you have any idea ?

    


    The code of the project could be found here : https://github.com/ieasybooks/taqtie.

    


  • How to use FFmpeg in UWP C# application ?

    6 septembre 2021, par MatS2510

    I'm creating an UWP app in C#, which downloads a video (.ts file with video and audio channels or .mp4 video file and .webm audio file, which should be merged) and allows user to trim a video duration and save the in three different modes : Video & Audio, Only video (disable audio channel) and Only audio (disable video channel).

    


    I tried to use MediaComposition, but it throws a lot of exceptions (probably because of input files extensions). I can't use FFmpeg wrapper or just execute command, because it's UWP app. Is it possible to use FFmpeg in the UWP app, and if yes, how can I do it ?
